Version 0.81 [August, 1995]
incorporated Tim Wegner's medium model code (thanks, Tim)
Version 0.82 [September, 1995]
[unspecified changes]
Version 0.85 [December, 1995]

Version 0.86 [January, 1996]
fixed bugs
improved documentation
Version 0.87 [January, 1996]

fixed progressive bugs
replaced tabs with spaces
cleaned up documentation
added callbacks for read/write and warning/error functions
Version 0.89 [June 5, 1996]
Added new initialization API to make libpng work better with shared libs
we now have png_create_read_struct(), png_create_write_struct(),
png_create_info_struct(), png_destroy_read_struct(), and
png_destroy_write_struct() instead of the separate calls to
malloc and png_read_init(), png_info_init(), and png_write_init()
Changed warning/error callback functions to fix bug - this means you
should use the new initialization API if you were using the old
png_set_message_fn() calls, and that the old API no longer exists
so that people are aware that they need to change their code
Changed filter selection API to allow selection of multiple filters
since it didn't work in previous versions of libpng anyways
Optimized filter selection code
Fixed png_set_background() to allow using an arbitrary RGB color for
paletted images
Fixed gamma and background correction for paletted images, so
png_correct_palette is not needed unless you are correcting an
external palette (you will need to #define PNG_CORRECT_PALETTE_SUPPORTED
in pngconf.h) - if nobody uses this, it may disappear in the future.
Fixed bug with Borland 64K memory allocation (Alexander Lehmann)
Fixed bug in interlace handling (Smarasderagd, I think)
Added more error checking for writing and image to reduce invalid files
Separated read and write functions so that they won't both be linked
into a binary when only reading or writing functionality is used
New pngtest image also has interlacing and zTXt
Updated documentation to reflect new API
Version 0.89c [June 17, 1996]
Bug fixes.
Version 0.90 [January, 1997]
Made CRC errors/warnings on critical and ancillary chunks configurable
libpng will use the zlib CRC routines by (compile-time) default
Changed DOS small/medium model memory support - needs zlib 1.04 (Tim Wegner)
Added external C++ wrapper statements to png.h (Gilles Dauphin)
Allow PNG file to be read when some or all of file signature has already
been read from the beginning of the stream. ****This affects the size
of info_struct and invalidates all programs that use a shared libpng****
Fixed png_filler() declarations
Fixed? background color conversions
Fixed order of error function pointers to match documentation
Current chunk name is now available in png_struct to reduce the number
of nearly identical error messages (will simplify multi-lingual
support when available)
Try to get ready for unknown-chunk callback functions:
- previously read critical chunks are flagged, so the chunk handling
routines can determine if the chunk is in the right place
- all chunk handling routines have the same prototypes, so we will
be able to handle all chunks via a callback mechanism
Try to fix Linux "setjmp" buffer size problems
Removed png_large_malloc, png_large_free, and png_realloc functions.
Version 0.95 [March, 1997]

Added macros for libpng to be compiled as a Windows DLL (Andreas Kupries)
Added "packswap" transformation, which changes the endianness of
packed-pixel bytes (Kevin Bracey)
Added "strip_alpha" transformation, which removes the alpha channel of
input images without using it (not necessarily a good idea)
Added "swap_alpha" transformation, which puts the alpha channel in front
of the color bytes instead of after
Removed all implicit variable tests which assume NULL == 0 (I think)
Changed several variables to "png_size_t" to show 16/32-bit limitations
Added new pCAL chunk read/write support
Added experimental filter selection weighting (Greg Roelofs)
Removed old png_set_rgbx() and png_set_xrgb() functions that have been
obsolete for about 2 years now (use png_set_filler() instead)
Added macros to read 16- and 32-bit ints directly from buffer, to be
used only on those systems that support it (namely PowerPC and 680x0)
With some testing, this may become the default for MACOS/PPC systems.
Only calculate CRC on data if we are going to use it
Added macros for zTXt compression type PNG_zTXt_COMPRESSION_???
Added macros for simple libpng debugging output selectable at compile time
Removed PNG_READ_END_MODE in progressive reader (Smarasderagd)
More description of info_struct in libpng.txt and png.h
More instructions in example.c
More chunk types tested in pngtest.c
Renamed pngrcb.c to pngset.c, and all png_read_ functions to be
png_set_. We now have corresponding png_get_
functions in pngget.c to get information in info_ptr. This isolates
the application from the internal organization of png_info_struct
(good for shared library implementations).

Minor corrections in libpng.txt
Added simple sRGB support (Glenn R-P)
Easier conditional compiling, e.g.,

png_get_spalettes, png_set_iCCP, png_set_spalettes (Eric S. Raymond).
NOTE: Applications that write text chunks MUST define png_text->lang
before calling png_set_text(). It must be set to NULL if you want to
write tEXt or zTXt chunks. If you want your application to be able to
run with older versions of libpng, use
#ifdef PNG_iTXt_SUPPORTED
png_text[i].lang = NULL;
#endif
Changed png_get_oFFs() and png_set_oFFs() to use signed rather than unsigned
offsets (Eric S. Raymond).
Combined PNG_READ_cHNK_SUPPORTED and PNG_WRITE_cHNK_SUPPORTED macros into
PNG_cHNK_SUPPORTED and combined the three types of PNG_text_SUPPORTED
macros, leaving the separate macros also available.

Version 1.0.5h [December 10, 1999]
NOTE: regarding the note for version 1.0.5e, the following must also
be included in your code:
png_text[i].translated_key = NULL;
Unknown chunk handling is now supported.
Option to eliminate all floating point support was added. Some new
fixed-point functions such as png_set_gAMA_fixed() were added.
Expanded tabs and removed trailing blanks in source files.
Version 1.0.5i [December 13, 1999]
Added some type casts to silence compiler warnings.
Renamed "png_free_spalette" to "png_free_spalettes" for consistency.

Added a test for up->location != 0 in the first instance of writing
unknown chunks in pngwrite.c
Changed "num" to "i" in png_free_spalettes() and png_free_unknowns() to
prevent recursion.

around buggy compilers.
Added new type "png_fixed_point" for integers that hold float*100000 values
Restored backward compatibility of tEXt/zTXt chunk processing:
Restored the first four members of png_text to the same order as v.1.0.5d.

text_length=0 when "text" contains iTXt data. Use the "compression"
member to distinguish among tEXt/zTXt/iTXt types. Added
PNG_ITXT_COMPRESSION_NONE (1) and PNG_ITXT_COMPRESSION_zTXt(2) macros.
The "Note" above, about backward incompatibility of libpng-1.0.5e, no
longer applies.
Fixed png_read|write_iTXt() to read|write parameters in the right order,
and to write the iTXt chunk after IDAT if it appears in the end_ptr.
Added pnggccrd.c, version of pngvcrd.c Intel assembler for gcc (Greg Roelofs)
Reversed the order of trying to write floating-point and fixed-point gAMA.

retrieving the associated user pointer (Glenn).
Version 1.0.5m [January 7, 2000]
Added high-level functions png_read_png(), png_write_png(), png_free_pixels().
Version 1.0.5n [January 9, 2000]
Added png_free_PLTE() function, and modified png_set_PLTE() to malloc its
own memory for info_ptr->palette. This makes it safe for the calling
application to free its copy of the palette any time after it calls
png_set_PLTE().
Version 1.0.5o [January 20, 2000]
Cosmetic changes only (removed some trailing blanks and TABs)
Version 1.0.5p [January 31, 2000]

new error handler that's planned for the next libpng release, and changed
example.c, pngtest.c, and contrib programs to use this macro.
Revised some of the DLL-export macros in pngconf.h (Greg Roelofs)
Fixed a bug in png_read_png() that caused it to fail to expand some images
that it should have expanded.
Fixed some mistakes in the unused and undocumented INCH_CONVERSIONS functions
in pngget.c
Changed the allocation of palette, history, and trans arrays back to
the version 1.0.5 method (linking instead of copying) which restores
backward compatibility with version 1.0.5. Added some remarks about
that in example.c. Added "free_me" member to info_ptr and png_ptr
and added png_free_data() function.
Updated makefile.linux and makefile.gccmmx to make directories conditionally.
Made cosmetic changes to pngasmrd.h
Added png_set_rows() and png_get_rows(), for use with png_read|write_png().

Version 1.0.6e [April 9, 2000]
Added png_data_freer() function.
In the code that checks for over-length tRNS chunks, added check of
info_ptr->num_trans as well as png_ptr->num_trans (Matthias Benckmann)
Minor revisions of libpng.txt/libpng.3.
Check for existing data and free it if the free_me flag is set, in png_set_*()
and png_handle_*().
Only define PNG_WEIGHTED_FILTERS_SUPPORTED when PNG_FLOATING_POINT_SUPPORTED
is defined.
Changed several instances of PNG_NO_CONSOLE_ID to PNG_NO_STDIO in pngrutil.c
and mentioned the purposes of the two macros in libpng.txt/libpng.3.

Relocated paragraph about png_set_background() in libpng.3/libpng.txt
and other revisions (Matthias Benckmann)
Relocated info_ptr->free_me, png_ptr->free_me, and other info_ptr and
png_ptr members to restore binary compatibility with libpng-1.0.5
(breaks compatibility with libpng-1.0.6).
Version 1.0.6h [April 24, 2000]
Changed shared library so-number pattern from 2.x.y.z to xy.z (this builds
libpng.so.10 & libpng.so.10.6h instead of libpng.so.2 & libpng.so.2.1.0.6h)
This is a temporary change for test purposes.
Version 1.0.6i [May 2, 2000]
Rearranged some members at the end of png_info and png_struct, to put
unknown_chunks_num and free_me within the original size of the png_structs
and free_me, png_read_user_fn, and png_free_fn within the original png_info,
because some old applications allocate the structs directly instead of
using png_create_*().
Added documentation of user memory functions in libpng.txt/libpng.3
Modified png_read_png so that it will use user_allocated row_pointers
if present, unless free_me directs that it be freed, and added description
of the use of png_set_rows() and png_get_rows() in libpng.txt/libpng.3.
Added PNG_LEGACY_SUPPORTED macro, and #ifdef out all new (since version
1.00) members of png_struct and png_info, to regain binary compatibility
when you define this macro. Capabilities lost in this event
are user transforms (new in version 1.0.0),the user transform pointer
(new in version 1.0.2), rgb_to_gray (new in 1.0.5), iCCP, sCAL, sPLT,
the high-level interface, and unknown chunks support (all new in 1.0.6).
This was necessary because of old applications that allocate the structs
directly as authors were instructed to do in libpng-0.88 and earlier,
instead of using png_create_*().
Added modes PNG_CREATED_READ_STRUCT and PNG_CREATED_WRITE_STRUCT which
can be used to detect codes that directly allocate the structs, and
code to check these modes in png_read_init() and png_write_init() and
generate a libpng error if the modes aren't set and PNG_LEGACY_SUPPORTED
was not defined.
Added makefile.intel and updated makefile.watcom (Pawel Mrochen)
Version 1.0.6j [May 3, 2000]
Overloaded png_read_init() and png_write_init() with macros that convert
calls to png_read_init_2() or png_write_init_2() that check the version
and structure sizes.
Version 1.0.7beta11 [May 7, 2000]
Removed the new PNG_CREATED_READ_STRUCT and PNG_CREATED_WRITE_STRUCT modes
which are no longer used.
Eliminated the three new members of png_text when PNG_LEGACY_SUPPORTED is
defined or when neither PNG_READ_iTXt_SUPPORTED nor PNG_WRITE_iTXt_SUPPORTED
is defined.
Made PNG_NO_READ|WRITE_iTXt the default setting, to avoid memory
overrun when old applications fill the info_ptr->text structure directly.
Added PNGAPI macro, and added it to the definitions of all exported functions.
Relocated version macro definitions ahead of the includes of zlib.h and
pngconf.h in png.h.
Version 1.0.7beta12 [May 12, 2000]
Revised pngset.c to avoid a problem with expanding the png_debug macro.
Deleted some extraneous defines from pngconf.h
Made PNG_NO_CONSOLE_IO the default condition when PNG_BUILD_DLL is defined.
Use MSC _RPTn debugging instead of fprintf if _MSC_VER is defined.
Added png_access_version_number() function.
Check for mask&PNG_FREE_CHNK (for TEXT, SCAL, PCAL) in png_free_data().
Expanded libpng.3/libpng.txt information about png_data_freer().
Version 1.0.7beta14 [May 17, 2000] (beta13 was not published)
Changed pnggccrd.c and pngvcrd.c to handle bad adaptive filter types as
warnings instead of errors, as pngrutil.c does.
Set the PNG_INFO_IDAT valid flag in png_set_rows() so png_write_png()
will actually write IDATs.
Made the default PNG_USE_LOCAL_ARRAYS depend on PNG_DLL instead of WIN32.
Make png_free_data() ignore its final parameter except when freeing data
that can have multiple instances (text, sPLT, unknowns).
Fixed a new bug in png_set_rows().
Removed info_ptr->valid tests from png_free_data(), as in version 1.0.5.
Added png_set_invalid() function.
Fixed incorrect illustrations of png_destroy_write_struct() in example.c.
Version 1.0.7beta15 [May 30, 2000]
Revised the deliberately erroneous Linux setjmp code in pngconf.h to produce
fewer error messages.
Rearranged checks for Z_OK to check the most likely path first in pngpread.c
and pngwutil.c.
Added checks in pngtest.c for png_create_*() returning NULL, and mentioned
in libpng.txt/libpng.3 the need for applications to check this.
Changed names of png_default_*() functions in pngtest to pngtest_*().
Changed return type of png_get_x|y_offset_*() from png_uint_32 to png_int_32.
Fixed some bugs in the unused PNG_INCH_CONVERSIONS functions in pngget.c
Set each pointer to NULL after freeing it in png_free_data().
Worked around a problem in pngconf.h; AIX's strings.h defines an "index"
macro that conflicts with libpng's png_color_16.index. (Dimitri
Papadapoulos)
Added "msvc" directory with MSVC++ project files (Simon-Pierre Cadieux).
Version 1.0.7beta16 [June 4, 2000]
Revised the workaround of AIX string.h "index" bug.
Added a check for overlength PLTE chunk in pngrutil.c.
Added PNG_NO_POINTER_INDEXING macro to use array-indexing instead of pointer
indexing in pngrutil.c and pngwutil.c to accommodate a buggy compiler.
Added a warning in png_decompress_chunk() when it runs out of data, e.g.
when it tries to read an erroneous PhotoShop iCCP chunk.
Added PNG_USE_DLL macro.
Revised the copyright/disclaimer/license notice.
Added contrib/msvctest directory

PNG_ALLOCATED macros to detect deprecated direct access to the
png_struct or info_struct members and other deprecated usage in
applications (John Bowler).

Moved libpng-config.in and libpng.pc-configure.in out of the scripts
directory, to libpng-config.in and libpng-pc.in, respectively, and
modified Makefile.am and configure.ac accordingly. Now "configure"
needs nothing from the "scripts" directory.
Avoid redefining PNG_CONST in pngconf.h
Version 1.4.0beta100 [November 14, 2009]
Removed ASM builds from projects/visualc6 and projects/visualc71

changes above and 1.2.30, 1.2.30rc01 and rc03 in 1.2.41 CHANGES. Someone
needs this feature.
Make the 'png_jmpbuf' macro expand to a call that records the correct
longjmp function as well as returning a pointer to the setjmp
jmp_buf buffer, and marked direct access to jmpbuf 'deprecated'.
(John Bowler)
Version 1.4.0beta104 [November 22, 2009]
Removed png_longjmp_ptr from scripts/*.def and libpng.3
Rebuilt configure scripts with autoconf-2.65

to put them in $prefix/include/libpng15 instead of in
$prefix/include/libpng/libpng15.
Version 1.4.0beta108 [December 11, 2009]
Removed leftover "-DPNG_CONFIGURE_LIBPNG" from contrib/pngminim/*/makefile
Relocated png_do_chop() to its original position in pngrtran.c; the

in some 16-bit datastreams (Yusaku Sugai).
Version 1.4.0beta109 [December 13, 2009]
Added "bit_depth" parameter to the private png_build_gamma_table() function.
Pass bit_depth=8 to png_build_gamma_table() when bit_depth is 16 but the
PNG_16_TO_8 transform has been set, to avoid unnecessary build of 16-bit
tables.
Version 1.4.0rc02 [December 20, 2009]

Version 1.4.1beta05 [January 26, 2010]
Relocated "int k" declaration in pngtest.c to minimize its scope.
Version 1.4.1beta06 [January 28, 2010]
Revised png_decompress_chunk() to use a two-pass method suggested by
John Bowler.
Version 1.4.1beta07 [February 6, 2010]
Folded some long lines in the source files.
Added defineable PNG_USER_CHUNK_CACHE_MAX, PNG_USER_CHUNK_MALLOC_MAX,
and a PNG_USER_LIMITS_SUPPORTED flag.
Eliminated use of png_ptr->irowbytes and reused the slot in png_ptr as
png_ptr->png_user_chunk_malloc_max.
Revised png_push_save_buffer() to do fewer but larger png_malloc() calls.
Version 1.4.1beta08 [February 6, 2010]

Removed malformed "incomplete struct declaration" of png_info from png.h
Version 1.5.0beta05 [February 12, 2010]
Removed PNG_DEPSTRUCT markup in pngstruct.h and pnginfo.h, and undid the
linewrapping that it entailed.
Revised comments in pngstruct.h and pnginfo.h and added pointers to
the libpng license.
Changed PNG_INTERNAL to PNG_EXPOSE_INTERNAL_STRUCTURES
Removed the cbuilder5 project, which has not been updated to 1.4.0.
Version 1.4.1beta12 and 1.5.0beta06 [February 14, 2010]
Fixed type declaration of png_get_chunk_malloc_max() in pngget.c (Daisuke
Nishikawa)
Version 1.5.0beta07 [omitted]
Version 1.5.0beta08 [February 19, 2010]
Changed #ifdef PNG_NO_STDIO_SUPPORTED to #ifdef PNG_NO_CONSOLE_IO_SUPPORTED
wherever png_snprintf() is used to construct error and warning messages.
Noted in scripts/makefile.mingw that it expects to be run under MSYS.
Removed obsolete unused MMX-querying support from contrib/gregbook
Added exported png_longjmp() function.
Removed the AIX redefinition of jmpbuf in png.h
Added -D_ALLSOURCE in configure.ac, makefile.aix, and CMakeLists.txt
when building on AIX.
Version 1.5.0beta09 [February 19, 2010]
Removed -D_ALLSOURCE from configure.ac, makefile.aix, and CMakeLists.txt.
Changed the name of png_ptr->jmpbuf to png_ptr->png_jmpbuf in pngstruct.h
Version 1.5.0beta10 [February 25, 2010]
Removed unused gzio.c from contrib/pngminim gather and makefile scripts
Removed replacement error handlers from contrib/gregbook. Because of
the new png_longjmp() function they are no longer needed.
Version 1.5.0beta11 [March 6, 2010]
Removed checking for already-included setjmp.h from pngconf.h
Fixed inconsistent indentations and made numerous cosmetic changes.
Revised the "SEE ALSO" style of libpng.3, libpngpf.3, and png.5
Version 1.5.0beta12 [March 9, 2010]
Moved "#include png.h" inside pngpriv.h and removed "#include png.h" from
the source files, along with "#define PNG_EXPOSE_INTERNAL_STRUCTURES"
and "#define PNG_NO_PEDANTIC_WARNINGS" (John Bowler).
Created new pngdebug.h and moved debug definitions there.
Version 1.5.0beta13 [March 10, 2010]
Protect pngstruct.h, pnginfo.h, and pngdebug.h from being included twice.
Revise the "#ifdef" blocks in png_inflate() so it will compile when neither
PNG_USER_CHUNK_MALLOC_MAX nor PNG_SET_CHUNK_MALLOC_LIMIT_SUPPORTED
is defined.
Removed unused png_measure_compressed_chunk() from pngpriv.h and libpngpf.3
Moved the 'config.h' support from pngconf.h to pngpriv.h
Removed PNGAPI from the png_longjmp_ptr typedef.
Eliminated dependence of pngtest.c on the private pngdebug.h file.
Make all png_debug macros into *unterminated* statements or
expressions (i.e. a trailing ';' must always be added) and correct
the format statements in various png_debug messages.
Version 1.5.0beta14 [March 14, 2010]
Removed direct access to png_ptr->io_ptr from the Windows code in pngtest.c
Revised Makefile.am to account for recent additions and replacements.
Corrected CE and OS/2 DEF files (scripts/png*def) for symbols removed and
added ordinal numbers to the Windows DEF file and corrected the duplicated
ordinal numbers on CE symbols that are commented out.
Added back in export symbols that can be present in the Windows build but
are disabled by default.
PNG_EXPORT changed to include an 'ordinal' field for DEF file generation.
PNG_CALLBACK added to make callback definitions uniform. PNGAPI split
into PNGCAPI (base C form), PNGAPI (exports) and PNGCBAPI (callbacks),
and appropriate changes made to all files. Cygwin builds re-hinged to
allow procedure call standard changes and to remove the need for the DEF
file (fixes build on Cygwin).
Enabled 'attribute' warnings that are relevant to library APIs and callbacks.
Changed rules for generation of the various symbol files and added a new
rule for a DEF file (which is also added to the distribution).
Updated the symbol file generation to stop it adding spurious spaces
to EOL (coming from preprocessor macro expansion). Added a facility
to join tokens in the output and rewrite *.dfn to use this.
Eliminated scripts/*.def in favor of libpng.def; updated projects/visualc71
and removed scripts/makefile.cygwin.
Made PNG_BUILD_DLL safe: it can be set whenever a DLL is being built.
Removed the include of sys/types.h - apparently unnecessary now on the
platforms on which it happened (all but Mac OS and RISC OS).
Moved the Mac OS test into pngpriv.h (the only place it is used.)
Version 1.5.0beta15 [March 17, 2010]
Added symbols.chk target to Makefile.am to validate the symbols in png.h
against the new DEF file scripts/symbols.def.
Changed the default DEF file back to pngwin.def.
Removed makefile.mingw.
Eliminated PNG_NO_EXTERN and PNG_ALL_EXTERN
Version 1.5.0beta16 [April 1, 2010]
Make png_text_struct independent of PNG_iTXt_SUPPORTED, so that
fields are initialized in all configurations. The READ/WRITE
macros (PNG_(READ|WRITE)_iTXt_SUPPORTED) still function as
before to disable code to actually read or write iTXt chunks
and iTXt_SUPPORTED can be used to detect presence of either
read or write support (but it is probably better to check for
the one actually required - read or write.)
Combined multiple png_warning() calls for a single error.
Restored the macro definition of png_check_sig().
Version 1.5.0beta17 [April 17, 2010]
Added some "(long)" typecasts to printf calls in png_handle_cHRM().
Documented the fact that png_set_dither() was disabled since libpng-1.4.0.
Reenabled png_set_dither() but renamed it to png_set_quantize() to reflect
more accurately what it actually does. At the same time, renamed
the PNG_DITHER_[RED,GREEN_BLUE]_BITS macros to
PNG_QUANTIZE_[RED,GREEN,BLUE]_BITS.
Added some "(long)" typecasts to printf calls in png_handle_cHRM().
Freeze build-time only configuration in the build.
In all prior versions of libpng most configuration options
controlled by compiler #defines had to be repeated by the
application code that used libpng. This patch changes this
so that compilation options that can only be changed at build
time are frozen in the build. Options that are compiler
dependent (and those that are system dependent) are evaluated
each time - pngconf.h holds these. Options that can be changed
per-file in the application are in png.h. Frozen options are
in the new installed header file pnglibconf.h (John Bowler)
Removed the xcode project because it has not been updated to work
with libpng-1.5.0.
Removed the ability to include optional pngusr.h
Version 1.5.0beta18 [April 17, 2010]
Restored the ability to include optional pngusr.h
Moved replacements for png_error() and png_warning() from the
contrib/pngminim project to pngerror.c, for use when warnings or
errors are disabled via PNG_NO_WARN or PNG_NO_ERROR_TEXT, to avoid
storing unneeded error/warning text.
Updated contrib/pngminim project to work with the new pnglibconf.h
Added some PNG_NO_* defines to contrib/pngminim/*/pngusr.h to save space.
Version 1.5.0beta19 [April 24, 2010]
Added PNG_{READ,WRITE}_INT_FUNCTIONS_SUPPORTED. This allows the functions
to read and write ints to be disabled independently of PNG_USE_READ_MACROS,
which allows libpng to be built with the functions even though the default
is to use the macros - this allows applications to choose at app build
time whether or not to use macros (previously impossible because the
functions weren't in the default build.)
Changed Windows calling convention back to __cdecl for API functions.
For Windows/x86 platforms only:
__stdcall is no longer needed for Visual Basic, so libpng-1.5.0 uses
__cdecl throughout (both API functions and callbacks) on Windows/x86
platforms.
Replaced visualc6 and visualc71 projects with new vstudio project
Relaxed the overly-restrictive permissions of some files.
Version 1.5.0beta20 [April 24, 2010]
Relaxed more overly-restrictive permissions of some files.
Version 1.5.0beta21 [April 27, 2010]
Removed some unwanted binary bytes and changed CRLF to NEWLINE in the new
vstudio project files, and some trivial editing of some files in the
scripts directory.
Set PNG_NO_READ_BGR, PNG_NO_IO_STATE, and PNG_NO_TIME_RFC1123 in
contrib/pngminim/decoder/pngusr.h to make a smaller decoder application.
Version 1.5.0beta22 [April 28, 2010]
Fixed dependencies of GET_INT_32 - it does not require READ_INT_FUNCTIONS
because it has a macro equivalent.
Improved the options.awk script; added an "everything off" option.
Revised contrib/pngminim to use the "everything off" option in pngusr.dfa.
Version 1.5.0beta23 [April 29, 2010]
Corrected PNG_REMOVED macro to take five arguments.
The macro was documented with two arguments (name,ordinal), however
the symbol checking .dfn files assumed five arguments. The five
argument form seems more useful so it is changed to that.
Corrected PNG_UNKNOWN_CHUNKS_SUPPORTED to PNG_HANDLE_AS_UNKNOWN_SUPPORTED
in gregbook/readpng2.c
Corrected protection of png_get_user_transform_ptr. The API declaration in
png.h is removed if both READ and WRITE USER_TRANSFORM are turned off
but was left defined in pngtrans.c
Added logunsupported=1 to cause pnglibconf.h to document disabled options.
This makes the installed pnglibconf.h more readable but causes no
other change. The intention is that users of libpng will find it
easier to understand if an API they need is missing.
Include png_reset_zstream() in png.c only when PNG_READ_SUPPORTED is defined.
Removed dummy_inflate.c from contrib/pngminim/encoder
Removed contrib/pngminim/*/gather.sh; gathering is now done in the makefile.
Version 1.5.0beta24 [May 7, 2010]
Use bitwise "&" instead of arithmetic mod in pngrutil.c calculation of the
offset of the png_ptr->rowbuf pointer into png_ptr->big_row_buf.
Added more blank lines for readability.
Version 1.5.0beta25 [June 18, 2010]
In pngpread.c: png_push_have_row() add check for new_row > height
Removed the now-redundant check for out-of-bounds new_row from example.c
Version 1.5.0beta26 [June 18, 2010]
In pngpread.c: png_push_process_row() add check for too many rows.
Version 1.5.0beta27 [June 18, 2010]
Removed the check added in beta25 as it is now redundant.
Version 1.5.0beta28 [June 20, 2010]
Rewrote png_process_IDAT_data to consistently treat extra data as warnings
and handle end conditions more cleanly.
Removed the new (beta26) check in png_push_process_row().
Version 1.5.0beta29 [June 21, 2010]
Revised scripts/options.awk to work on Sunos (but still doesn't work)
Added comment to options.awk and contrib/pngminim/*/makefile to try nawk.
Version 1.5.0beta30 [June 22, 2010]
Stop memory leak when reading a malformed sCAL chunk.
Version 1.5.0beta31 [June 26, 2010]
Revised pngpread.c patch of beta28 to avoid an endless loop.
Removed some trailing blanks.
Version 1.5.0beta32 [June 26, 2010]
Removed leftover scripts/options.patch and scripts/options.rej
Version 1.5.0beta33 [July 6, 3010]
Made FIXED and FLOATING options consistent in the APIs they enable and
disable. Corrected scripts/options.awk to handle both command line
options and options specified in the .dfa files.
Changed char *msg to PNG_CONST char *msg in pngrutil.c
Make png_set_sRGB_gAMA_and_cHRM set values using either the fixed or
floating point APIs, but not both.
Reversed patch to remove error handler when the jmp_buf is stored in the
main program structure, not the png_struct.
The error handler is needed because the default handler in libpng will
always use the jmp_buf in the library control structure; this is never
set. The gregbook code is a useful example because, even though it
uses setjmp/longjmp, it shows how error handling can be implemented
using control mechanisms not directly supported by libpng. The
technique will work correctly with mechanisms such as Microsoft
Structure Exceptions or C++ exceptions (compiler willing - note that gcc
does not by default support interworking of C and C++ error handling.)
Reverted changes to call png_longjmp in contrib/gregbook where it is not
appropriate. If mainprog->jmpbuf is used by setjmp, then png_longjmp
cannot be used.
Changed "extern PNG_EXPORT" to "PNG_EXPORT" in png.h (Jan Nijtmans)
Changed "extern" to "PNG_EXTERN" in pngpriv.h (except for the 'extern "C" {')
Version 1.5.0beta34 [July 12, 2010]
Put #ifndef PNG_EXTERN, #endif around the define PNG_EXTERN in pngpriv.h
Version 1.5.0beta35 [July 24, 2010]
Removed some newly-added TAB characters.
Added -DNO_PNG_SNPRINTF to CFLAGS in scripts/makefile.dj2
Moved the definition of png_snprintf() outside of the enclosing
#ifdef blocks in pngconf.h
Version 1.5.0beta36 [July 29, 2010]
Patches by John Bowler:
Fixed point APIs are now supported throughout (no missing APIs).
Internal fixed point arithmetic support exists for all internal floating
point operations.
sCAL validates the floating point strings it is passed.
Safe, albeit rudimentary, Watcom support is provided by PNG_API_RULE==2
Two new APIs exist to get the number of passes without turning on the
PNG_INTERLACE transform and to get the number of rows in the current
pass.
A new test program, pngvalid.c, validates the gamma code.
Errors in the 16-bit gamma correction (overflows) have been corrected.
cHRM chunk testing is done consistently (previously the floating point
API bypassed it, because the test really didn't work on FP, now the test
is performed on the actual values to be stored in the PNG file so it
works in the FP case too.)
Most floating point APIs now simply call the fixed point APIs after
converting the values to the fixed point form used in the PNG file.
The standard headers no longer include zlib.h, which is currently only
required for pngstruct.h and can therefore be internal.
Revised png_get_int_32 to undo the PNG two's complement representation of
negative numbers.
Version 1.5.0beta37 [July 30, 2010]
Added a typecast in png_get_int_32() in png.h and pngrutil.h to avoid
a compiler warning.
Replaced oFFs 0,0 with oFFs -10,20 in pngtest.png
Version 1.5.0beta38 [July 31, 2010]
Implemented remaining "_fixed" functions.
Corrected a number of recently introduced warnings mostly resulting from
safe but uncast assignments to shorter integers. Also added a zlib
VStudio release library project because the latest zlib Official Windows
build does not include such a thing.
Revised png_get_int_16() to be similar to png_get_int_32().
Restored projects/visualc71.
Version 1.5.0beta39 [August 2, 2010]
VisualC/GCC warning fixes, VisualC build fixes
The changes include support for function attributes in VC in addition to
those already present in GCC - necessary because without these some
warnings are unavoidable. Fixes include signed/unsigned fixes in
pngvalid and checks with gcc -Wall -Wextra -Wunused.
VC requires function attributes on function definitions as well as
declarations, PNG_FUNCTION has been added to enable this and the
relevant function definitions changed.
Version 1.5.0beta40 [August 6, 2010]
Correct use of _WINDOWS_ in pngconf.h
Removed png_mem_ #defines; they are no longer used.
Added the sRGB chunk to pngtest.png
Version 1.5.0beta41 [August 11, 2010]
Added the cHRM chunk to pngtest.png
Don't try to use version-script with cygwin/mingw.
Revised contrib/gregbook to work under cygwin/mingw.
Version 1.5.0beta42 [August 18, 2010]
Add .dll.a to the list of extensions to be symlinked by Makefile.am (Yaakov)
Made all API functions that have const arguments and constant string
literal pointers declare them (John Bowler).
Version 1.5.0beta43 [August 20, 2010]
Removed spurious tabs, shorten long lines (no source change)
Also added scripts/chkfmt to validate the format of all the files that can
reasonably be validated (it is suggested to run "make distclean" before
checking, because some machine generated files have long lines.)
Reformatted the CHANGES file to be more consistent throughout.
Made changes to address various issues identified by GCC, mostly
signed/unsigned and shortening problems on assignment but also a few
difficult to optimize (for GCC) loops.
Fixed non-GCC fixed point builds. In png.c a declaration was misplaced
in an earlier update. Fixed to declare the auto variables at the head.
Use cexcept.h in pngvalid.c.
Version 1.5.0beta44 [August 24, 2010]
Updated CMakeLists.txt to use CMAKE_INSTALL_LIBDIR variable; useful for
installing libpng in /usr/lib64 (Funda Wang).
Revised CMakeLists.txt to put the man pages in share/man/man* not man/man*
Revised CMakeLists.txt to make symlinks instead of copies when installing.
Changed PNG_LIB_NAME from pngNN to libpngNN in CMakeLists.txt (Philip Lowman)
Implemented memory checks within pngvalid
Reformatted/rearranged pngvalid.c to assist use of progressive reader.
Check interlaced images in pngvalid
Clarified pngusr.h comments in pnglibconf.dfa
Simplified the pngvalid error-handling code now that cexcept.h is in place.
Implemented progressive reader in pngvalid.c for standard tests
Implemented progressive read in pngvalid.c gamma tests
Turn on progressive reader in pngvalid.c by default and tidy code.
Version 1.5.0beta45 [August 26, 2010]
Added an explicit make step to projects/vstudio for pnglibconf.h
Also corrected zlib.vcxproj into which Visual Studio had introduced
what it calls an "authoring error". The change to make pnglibconf.h
simply copies the file; in the future it may actually generate the
file from scripts/pnglibconf.dfa as the other build systems do.
Changed pngvalid to work when floating point APIs are disabled
Renamed the prebuilt scripts/pnglibconf.h to scripts/pnglibconf.h.prebuilt
Supply default values for PNG_USER_PRIVATEBUILD and PNG_USER_DLLFNAME_POSTFIX
in pngpriv.h in case the user neglected to define them in their pngusr.h
Version 1.5.0beta46 [August 28, 2010]
Added new private header files to libpng_sources in CMakeLists.txt
Added PNG_READ_16BIT, PNG_WRITE_16BIT, and PNG_16BIT options.
Added reference to scripts/pnglibconf.h.prebuilt in the visualc71 project.
Version 1.5.0beta47 [September 11, 2010]
Fixed a number of problems with 64-bit compilation reported by Visual
Studio 2010 (John Bowler).
Version 1.5.0beta48 [October 4, 2010]
Updated CMakeLists.txt (Philip Lowman).
Revised autogen.sh to recognize and use $AUTOCONF, $AUTOMAKE, $AUTOHEADER,
$AUTOPOINT, $ACLOCAL and $LIBTOOLIZE
Fixed problem with symbols creation in Makefile.am which was assuming that
all versions of ccp write to standard output by default (Martin Banky). The
bug was introduced in libpng-1.2.9beta5.
Removed unused mkinstalldirs.
Version 1.5.0beta49 [October 8, 2010]
Undid Makefile.am revision of 1.5.0beta48.
Version 1.5.0beta50 [October 14, 2010]
Revised Makefile.in to account for mkinstalldirs being removed.
Added some "(unsigned long)" typecasts in printf statements in pngvalid.c.
Suppressed a compiler warning in png_handle_sPLT().
Check for out-of-range text compression mode in png_set_text().
Version 1.5.0beta51 [October 15, 2010]
Changed embedded dates to "(PENDING RELEASE) in beta releases (and future
rc releases) to minimize the difference between releases.
Version 1.5.0beta52 [October 16, 2010]
Restored some of the embedded dates (in png.h, png.c, documentation, etc.)
Version 1.5.0beta53 [October 18, 2010]
Updated INSTALL to mention using "make maintainer-clean" and to remove
obsolete statement about a custom ltmain.sh
Disabled "color-tests" by default in Makefile.am so it will work with
automake versions earlier than 1.11.1
Use document name "libpng-manual.txt" instead of "libpng-.txt"
to simplify version differences.
Removed obsolete remarks about setjmp handling from INSTALL.
Revised and renamed the typedef in png.h and png.c that was designed
to catch library and header mismatch.
Version 1.5.0beta54 [November 10, 2010]
Require 48 bytes, not 64 bytes, for big_row_buf in overflow checks.
Used a consistent structure for the pngget.c functions.
Version 1.5.0beta55 [November 21, 2010]
Revised png_get_uint_32, png_get_int_32, png_get_uint_16 (Cosmin)
Moved reading of file signature into png_read_sig (Cosmin)
Fixed atomicity of chunk header serialization (Cosmin)
Added test for io_state in pngtest.c (Cosmin)
Added "#!/bin/sh" at the top of contrib/pngminim/*/gather.sh scripts.
Changes to remove gcc warnings (John Bowler)
Certain optional gcc warning flags resulted in warnings in libpng code.
With these changes only -Wconversion and -Wcast-qual cannot be turned on.
Changes are trivial rearrangements of code. -Wconversion is not possible
for pngrutil.c (because of the widespread use of += et al on variables
smaller than (int) or (unsigned int)) and -Wcast-qual is not possible
with pngwio.c and pngwutil.c because the 'write' callback and zlib
compression both fail to declare their input buffers with 'const'.
Version 1.5.0beta56 [December 7, 2010]
Added the private PNG_UNUSED() macro definition in pngpriv.h.
Added some commentary about PNG_EXPORT in png.h and pngconf.h
Revised PNG_EXPORT() macro and added PNG_EXPORTA() macro, with the
objective of simplifying and improving the cosmetic appearance of png.h.
Fixed some incorrect "=" macro names in pnglibconf.dfa
Included documentation of changes in 1.5.0 from 1.4.x in libpng-manual.txt
Version 1.5.0beta57 [December 9, 2010]
Documented the pngvalid gamma error summary with additional comments and
print statements.
Improved missing symbol handling in checksym.awk; symbols missing in both
the old and new files can now be optionally ignored, treated as errors
or warnings.
Removed references to pngvcrd.c and pnggccrd.c from the vstudio project.
Updated "libpng14" to "libpng15" in the visualc71 project.
Enabled the strip16 tests in pngvalid.`
Don't display test results (except PASS/FAIL) when running "make test".
Instead put them in pngtest-log.txt
Added "--with-zprefix=" to configure.ac
Updated the prebuilt configuration files to autoconf version 2.68
Version 1.5.0beta58 [December 19, 2010]
Fixed interlace image handling and add test cases (John Bowler)
Fixed the clean rule in Makefile.am to remove pngtest-log.txt
Made minor changes to work around warnings in gcc 3.4
Version 1.5.0rc01 [December 27, 2010]
No changes.
Version 1.5.0rc02 [December 27, 2010]
Eliminated references to the scripts/*.def files in project/visualc71.
Version 1.5.0rc03 [December 28, 2010]
Eliminated scripts/*.def and revised Makefile.am accordingly
Version 1.5.0rc04 [December 29, 2010]
Fixed bug in background transformation handling in pngrtran.c (it was
looking for the flag in png_ptr->transformations instead of in
png_ptr->flags) (David Raymond).
Version 1.5.0rc05 [December 31, 2010]
Fixed typo in a comment in CMakeLists.txt (libpng14 => libpng15) (Cosmin)
Version 1.5.0rc06 [January 4, 2011]
Changed the new configure option "zprefix=string" to "zlib-prefix=string"
Version 1.5.0rc07 [January 4, 2011]
Updated copyright year.
Version 1.5.0 [January 6, 2011]
No changes.
version 1.5.1beta01 [January 8, 2011]
Added description of png_set_crc_action() to the manual.
Added a note in the manual that the type of the iCCP profile was changed
from png_charpp to png_bytepp in png_get_iCCP(). This change happened
in version 1.5.0beta36 but is not noted in the CHANGES. Similarly,
it was changed from png_charpp to png_const_bytepp in png_set_iCCP().
Ensure that png_rgb_to_gray ignores palette mapped images, if libpng
internally happens to call it with one, and fixed a failure to handle
palette mapped images correctly. This fixes CVE-2690.
Version 1.5.1beta02 [January 14, 2011]
Fixed a bug in handling of interlaced images (bero at arklinux.org).
Updated CMakeLists.txt (Clifford Yapp)
Version 1.5.1beta03 [January 14, 2011]
Fixed typecasting of some png_debug() statements (Cosmin)
Version 1.5.1beta04 [January 16, 2011]
Updated documentation of png_set|get_tRNS() (Thomas Klausner).
Mentioned in the documentation that applications must #include "zlib.h"
if they need access to anything in zlib.h, and that a number of
macros such as png_memset() are no longer accessible by applications.
Corrected pngvalid gamma test "sample" function to access all of the color
samples of each pixel, instead of sampling the red channel three times.
Prefixed variable names index, div, exp, gamma with "png_" to avoid "shadow"
warnings, and (mistakenly) changed png_exp() to exp().
Version 1.5.1beta05 [January 16, 2011]
Changed variable names png_index, png_div, png_exp, and png_gamma to
char_index, divisor, exp_b10, and gamma_val, respectively, and
changed exp() back to png_exp().
Version 1.5.1beta06 [January 20, 2011]
Prevent png_push_crc_skip() from hanging while reading an unknown chunk
or an over-large compressed zTXt chunk with the progressive reader.
Eliminated more GCC "shadow" warnings.
Revised png_fixed() in png.c to avoid compiler warning about reaching the
end without returning anything.
Version 1.5.1beta07 [January 22, 2011]
In the manual, describe the png_get_IHDR() arguments in the correct order.
Added const_png_structp and const_png_infop types, and used them in
prototypes for most png_get_*() functions.
Version 1.5.1beta08 [January 23, 2011]
Added png_get_io_chunk_type() and deprecated png_get_io_chunk_name()
Added synopses for the IO_STATE functions and other missing synopses
to the manual. Removed the synopses from libpngpf.3 because they
were out of date and no longer useful. Better information can be
obtained by reading the prototypes and comments in pngpriv.h
Attempted to fix cpp on Solaris with S. Studio 12 cc, fix build
Added a make macro DFNCPP that is a CPP that will accept the tokens in
a .dfn file and adds configure stuff to test for such a CPP. ./configure
should fail if one is not available.
Corrected const_png_ in png.h to png_const_ to avoid polluting the namespace.
Added png_get_current_row_number and png_get_current_pass_number for the
benefit of the user transform callback.
Added png_process_data_pause and png_process_data_skip for the benefit of
progressive readers that need to stop data processing or want to optimize
skipping of unread data (e.g., if the reader marks a chunk to be skipped.)
Version 1.5.1beta09 [January 24, 2011]
Enhanced pngvalid, corrected an error in gray_to_rgb, corrected doc error.
pngvalid contains tests of transforms, which tests are currently disabled
because they are incompletely tested. gray_to_rgb was failing to expand
the bit depth for smaller bit depth images; this seems to be a long
standing error and resulted, apparently, in invalid output
(CVE-2011-0408, CERT VU#643140). The documentation did not accurately
describe what libpng really does when converting RGB to gray.
Version 1.5.1beta10 [January 27, 2010]
Fixed incorrect examples of callback prototypes in the manual, that were
introduced in libpng-1.0.0.
In addition the order of the png_get_uint macros with respect to the
relevant function definitions has been reversed. This helps the
preprocessing of the symbol files be more robust. Furthermore, the
symbol file preprocessing now uses -DPNG_NO_USE_READ_MACROS even when
the library may actually be built with PNG_USE_READ_MACROS; this stops
the read macros interfering with the symbol file format.
Made the manual, synopses, and function prototypes use the function
argument names file_gamma, int_file_gamma, and srgb_intent consistently.
Version 1.5.1beta11 [January 28, 2011]
Changed PNG_UNUSED from "param=param;" to "{if(param){}}".
Corrected local variable type in new API png_process_data_skip()
The type was self-evidently incorrect but only causes problems on 64-bit
architectures.
Added transform tests to pngvalid and simplified the arguments.
Version 1.5.1rc01 [January 29, 2011]
No changes.
Version 1.5.1rc02 [January 31, 2011]
Added a request in the manual that applications do not use "png_" or
"PNG_" to begin any of their own symbols.
Changed PNG_UNUSED to "(void)param;" and updated the commentary in pngpriv.h
Version 1.5.1 [February 3, 2011]
No changes.
Version 1.5.2beta01 [February 13, 2011]
More -Wshadow fixes for older gcc compilers. Older gcc versions apparently
check formal parameters names in function declarations (as well as
definitions) to see if they match a name in the global namespace.
Revised PNG_EXPORTA macro to not use an empty parameter, to accommodate the
old VisualC++ preprocessor.
Turned on interlace handling in png_read_png().
Fixed gcc pedantic warnings.
Handle longjmp in Cygwin.
Fixed png_get_current_row_number() in the interlaced case.
Cleaned up ALPHA flags and transformations.
Implemented expansion to 16 bits.
Version 1.5.2beta02 [February 19, 2011]
Fixed mistake in the descriptions of user read_transform and write_transform
function prototypes in the manual. The row_info struct is png_row_infop.
Reverted png_get_current_row_number() to previous (1.5.2beta01) behavior.
Corrected png_get_current_row_number documentation
Fixed the read/write row callback documentation.
This documents the current behavior, where the callback is called after
every row with information pertaining to the next row.
Version 1.5.2beta03 [March 3, 2011]
Fixed scripts/makefile.vcwin32
Updated contrib/pngsuite/README to add the word "modify".
Define PNG_ALLOCATED to blank when _MSC_VER<1300.
Version 1.5.2rc01 [March 19, 2011]
Define remaining attributes to blank when MSC_VER<1300.
ifdef out mask arrays in pngread.c when interlacing is not supported.
Version 1.5.2rc02 [March 22, 2011]
Added a hint to try CPP=/bin/cpp if "cpp -E" fails in scripts/pnglibconf.mak
and in contrib/pngminim/*/makefile, eg., on SunOS 5.10, and removed "strip"
from the makefiles.
Fixed a bug (present since libpng-1.0.7) that makes png_handle_sPLT() fail
to compile when PNG_NO_POINTER_INDEXING is defined (Chubanov Kirill)
Version 1.5.2rc03 [March 24, 2011]
Don't include standard header files in png.h while building the symbol table,
to avoid cpp failure on SunOS (introduced PNG_BUILDING_SYMBOL_TABLE macro).
Version 1.5.2 [March 31, 2011]
No changes.
Version 1.5.3beta01 [April 1, 2011]
Re-initialize the zlib compressor before compressing non-IDAT chunks.
Added API functions (png_set_text_compression_level() and four others) to
set parameters for zlib compression of non-IDAT chunks.
Version 1.5.3beta02 [April 3, 2011]
Updated scripts/symbols.def with new API functions.
Only compile the new zlib re-initializing code when text or iCCP is
supported, using PNG_WRITE_COMPRESSED_TEXT_SUPPORTED macro.
Improved the optimization of the zlib CMF byte (see libpng-1.2.6beta03).
Optimize the zlib CMF byte in non-IDAT compressed chunks
Version 1.5.3beta03 [April 16, 2011]
Fixed gcc -ansi -pedantic compile. A strict ANSI system does not have
snprintf, and the "__STRICT_ANSI__" detects that condition more reliably
than __STDC__ (John Bowler).
Removed the PNG_PTR_NORETURN attribute because it too dangerous. It tells
the compiler that a user supplied callback (the error handler) does not
return, yet there is no guarantee in practice that the application code
will correctly implement the error handler because the compiler only
issues a warning if there is a mistake (John Bowler).
Removed the no-longer-used PNG_DEPSTRUCT macro.
Updated the zlib version to 1.2.5 in the VStudio project.
Fixed 64-bit builds where png_uint_32 is smaller than png_size_t in
pngwutil.c (John Bowler).
Fixed bug with stripping the filler or alpha channel when writing, that
was introduced in libpng-1.5.2beta01 (bug report by Andrew Church).
Version 1.5.3beta04 [April 27, 2011]
Updated pngtest.png with the new zlib CMF optimization.
Cleaned up conditional compilation code and of background/gamma handling
Internal changes only except a new option to avoid compiling the
png_build_grayscale_palette API (which is not used at all internally.)
The main change is to move the transform tests (READ_TRANSFORMS,
WRITE_TRANSFORMS) up one level to the caller of the APIs. This avoids
calls to spurious functions if all transforms are disabled and slightly
simplifies those functions. Pngvalid modified to handle this.
A minor change is to stop the strip_16 and expand_16 interfaces from
disabling each other; this allows the future alpha premultiplication
code to use 16-bit intermediate values while still producing 8-bit output.
png_do_background and png_do_gamma have been simplified to take a single
pointer to the png_struct rather than pointers to every item required
from the png_struct. This makes no practical difference to the internal
code.
A serious bug in the pngvalid internal routine 'standard_display_init' has
been fixed - this failed to initialize the red channel and accidentally
initialized the alpha channel twice.
Changed png_struct jmp_buf member name from png_jmpbuf to tmp_jmpbuf to
avoid a possible clash with the png_jmpbuf macro on some platforms.
Version 1.5.3beta05 [May 6, 2011]
Added the "_POSIX_SOURCE" feature test macro to ensure libpng sees the
correct API. _POSIX_SOURCE is defined in pngpriv.h, pngtest.c and
pngvalid.c to ensure that POSIX conformant systems disable non-POSIX APIs.
Removed png_snprintf and added formatted warning messages. This change adds
internal APIs to allow png_warning messages to have parameters without
requiring the host OS to implement snprintf. As a side effect the
dependency of the tIME-supporting RFC1132 code on stdio is removed and
PNG_NO_WARNINGS does actually work now.
Pass "" instead of '\0' to png_default_error() in png_err(). This mistake
was introduced in libpng-1.2.20beta01. This fixes CVE-2011-2691.
Added PNG_WRITE_OPTIMIZE_CMF_SUPPORTED macro to make the zlib "CMF" byte
optimization configurable.
IDAT compression failed if preceded by a compressed text chunk (bug
introduced in libpng-1.5.3beta01-02). This was because the attempt to
reset the zlib stream in png_write_IDAT happened after the first IDAT
chunk had been deflated - much too late. In this change internal
functions were added to claim/release the z_stream and, hopefully, make
the code more robust. Also deflateEnd checking is added - previously
libpng would ignore an error at the end of the stream.
Version 1.5.3beta06 [May 8, 2011]
Removed the -D_ALL_SOURCE from definitions for AIX in CMakeLists.txt
Implemented premultiplied alpha support: png_set_alpha_mode API
Version 1.5.3beta07 [May 11, 2011]
Added expand_16 support to the high level interface.
Added named value and 'flag' gamma support to png_set_gamma. Made a minor
change from the previous (unreleased) ABI/API to hide the exact value used
for Macs - it's not a good idea to embed this in the ABI!
Moved macro definitions for PNG_HAVE_IHDR, PNG_HAVE_PLTE, and PNG_AFTER_IDAT
from pngpriv.h to png.h because they must be visible to applications
that call png_set_unknown_chunks().
Check for up->location !PNG_AFTER_IDAT when writing unknown chunks
before IDAT.
Version 1.5.3beta08 [May 16, 2011]
Improved "pngvalid --speed" to exclude more of pngvalid from the time.
Documented png_set_alpha_mode(), other changes in libpng.3/libpng-manual.txt
The cHRM chunk now sets the defaults for png_set_rgb_to_gray() (when negative
parameters are supplied by the caller), while in the absence of cHRM
sRGB/Rec 709 values are still used. This introduced a divide-by-zero
bug in png_handle_cHRM().
The bKGD chunk no longer overwrites the background value set by
png_set_background(), allowing the latter to be used before the file
header is read. It never performed any useful function to override
the default anyway.
Added memory overwrite and palette image checks to pngvalid.c
Previously palette image code was poorly checked. Since the transformation
code has a special palette path in most cases this was a severe weakness.
Minor cleanup and some extra checking in pngrutil.c and pngrtran.c. When
expanding an indexed image, always expand to RGBA if transparency is
present.
Version 1.5.3beta09 [May 17, 2011]
Reversed earlier 1.5.3 change of transformation order; move png_expand_16
back where it was. The change doesn't work because it requires 16-bit
gamma tables when the code only generates 8-bit ones. This fails
silently; the libpng code just doesn't do any gamma correction. Moving
the tests back leaves the old, inaccurate, 8-bit gamma calculations, but
these are clearly better than none!
Version 1.5.3beta10 [May 20, 2011]
png_set_background() and png_expand_16() did not work together correctly.
This problem is present in 1.5.2; if png_set_background is called with
need_expand false and the matching 16 bit color libpng erroneously just
treats it as an 8-bit color because of where png_do_expand_16 is in the
transform list. This simple fix reduces the supplied colour to 8-bits,
so it gets smashed, but this is better than the current behavior.
Added tests for expand16, more fixes for palette image tests to pngvalid.
Corrects the code for palette image tests and disables attempts to
validate palette colors.
Version 1.5.3rc01 [June 3, 2011]
No changes.
Version 1.5.3rc02 [June 8, 2011]
Fixed uninitialized memory read in png_format_buffer() (Bug report by
Frank Busse, CVE-2011-2501, related to CVE-2004-0421).
Version 1.5.3beta11 [June 11, 2011]
Fixed png_handle_sCAL which is broken in 1.5. This fixes CVE 2011-2692.
Added sCAL to pngtest.png
Revised documentation about png_set_user_limits() to say that it also affects
png writing.
Revised handling of png_set_user_limits() so that it can increase the
limit beyond the PNG_USER_WIDTH|HEIGHT_MAX; previously it could only
reduce it.
Make the 16-to-8 scaling accurate. Dividing by 256 with no rounding is
wrong (high by one) 25% of the time. Dividing by 257 with rounding is
wrong in 128 out of 65536 cases. Getting the right answer all the time
without division is easy.
Added "_SUPPORTED" to the PNG_WRITE_CUSTOMIZE_ZTXT_COMPRESSION macro.
Added projects/owatcom, an IDE project for OpenWatcom to replace
scripts/makefile.watcom. This project works with OpenWatcom 1.9. The
IDE autogenerates appropriate makefiles (libpng.mk) for batch processing.
The project is configurable, unlike the Visual Studio project, so long
as the developer has an awk.
Changed png_set_gAMA to limit the gamma value range so that the inverse
of the stored value cannot overflow the fixed point representation,
and changed other things OpenWatcom warns about.
Revised pngvalid.c to test PNG_ALPHA_MODE_SUPPORTED correctly. This allows
pngvalid to build when ALPHA_MODE is not supported, which is required if
it is to build on libpng 1.4.
Removed string/memory macros that are no longer used and are not
necessarily fully supportable, particularly png_strncpy and png_snprintf.
Added log option to pngvalid.c and attempted to improve gamma messages.
Version 1.5.3 [omitted]
People found the presence of a beta release following an rc release
to be confusing; therefore we bump the version to libpng-1.5.4beta01
and there will be no libpng-1.5.3 release.
Version 1.5.4beta01 [June 14, 2011]
Made it possible to undefine PNG_READ_16_TO_8_ACCURATE_SCALE_SUPPORTED
to get the same (inaccurate) output as libpng-1.5.2 and earlier.
Moved definitions of PNG_HAVE_IHDR, PNG_AFTER_IDAT, and PNG_HAVE_PLTE
outside of an unknown-chunk block in png.h because they are also
needed for other uses.
Version 1.5.4beta02 [June 14, 2011]
Fixed and clarified LEGACY 16-to-8 scaling code.
Added png_set_chop_16() API, to match inaccurate results from previous
libpng versions.
Removed the ACCURATE and LEGACY options (they are no longer useable)
Use the old scaling method for background if png_set_chop_16() was
called.
Made png_set_chop_16() API removeable by disabling PNG_CHOP_16_TO_8_SUPPORTED
Version 1.5.4beta03 [June 15, 2011]
Fixed a problem in png_do_expand_palette() exposed by optimization in
1.5.3beta06
Also removed a spurious and confusing "trans" member ("trans") from png_info.
The palette expand optimization prevented expansion to an intermediate RGBA
form if tRNS was present but alpha was marked to be stripped; this exposed
a check for tRNS in png_do_expand_palette() which is inconsistent with the
code elsewhere in libpng.
Correction to the expand_16 code; removed extra instance of
png_set_scale_16_to_8 from pngpriv.h
Version 1.5.4beta04 [June 16, 2011]
Added a missing "#ifdef PNG_READ_BACKGROUND_SUPPORTED/#endif" in pngrtran.c
Added PNG_TRANSFORM_CHOP_16 to the high-level read transforms.
Made PNG_READ_16_TO_8_ACCURATE_SCALE configurable again. If this is
not enabled, png_set_strip_16() and png_do_scale_16_to_8() aren't built.
Revised contrib/visupng, gregbook, and pngminim to demonstrate chop_16_to_8
Version 1.5.4beta05 [June 16, 2011]
Renamed png_set_strip_16() to png_set_scale_16() and renamed
png_set_chop_16() to png_set_strip(16) in an attempt to minimize the
behavior changes between libpng14 and libpng15.
Version 1.5.4beta06 [June 18, 2011]
Fixed new bug that was causing both strip_16 and scale_16 to be applied.
Version 1.5.4beta07 [June 19, 2011]
Fixed pngvalid, simplified macros, added checking for 0 in sCAL.
The ACCURATE scale macro is no longer defined in 1.5 - call the
png_scale_16_to_8 API. Made sure that PNG_READ_16_TO_8 is still defined
if the png_strip_16_to_8 API is present. png_check_fp_number now
maintains some state so that positive, negative and zero values are
identified. sCAL uses these to be strictly spec conformant.
Version 1.5.4beta08 [June 23, 2011]
Fixed pngvalid if ACCURATE_SCALE is defined.
Updated scripts/pnglibconf.h.prebuilt.
Version 1.5.4rc01 [June 30, 2011]
Define PNG_ALLOCATED to "restrict" only if MSC_VER >= 1400.
Version 1.5.4 [July 7, 2011]
No changes.
Version 1.5.5beta01 [July 13, 2011]
Fixed some typos and made other minor changes in the manual.
Updated contrib/pngminus/makefile.std (Samuli Souminen)
Version 1.5.5beta02 [July 14, 2011]
Revised Makefile.am and Makefile.in to look in the right directory for
pnglibconf.h.prebuilt
Version 1.5.5beta03 [July 27, 2011]
Enabled compilation with g++ compiler. This compiler does not recognize
the file extension, so it always compiles with C++ rules. Made minor
changes to pngrutil.c to cast results where C++ expects it but C does not.
Minor editing of libpng.3 and libpng-manual.txt.
Version 1.5.5beta04 [July 29, 2011]
Revised CMakeLists.txt (Clifford Yapp)
Updated commentary about the png_rgb_to_gray() default coefficients
in the manual and in pngrtran.c
Version 1.5.5beta05 [August 17, 2011]
Prevent unexpected API exports from non-libpng DLLs on Windows. The "_DLL"
is removed from the test of whether a DLL is being built (this erroneously
caused the libpng APIs to be marked as DLL exports in static builds under
Microsoft Visual Studio). Almost all of the libpng building configuration
is moved from pngconf.h to pngpriv.h, but PNG_DLL_EXPORT remains in
pngconf.h, though, so that it is colocated with the import definition (it
is no longer used anywhere in the installed headers). The VStudio project
definitions have been cleaned up: "_USRDLL" has been removed from the
static library builds (this was incorrect), and PNG_USE_DLL has been added
to pngvalid to test the functionality (pngtest does not supply it,
deliberately). The spurious "_EXPORTS" has been removed from the
libpng build (all these errors were a result of copy/paste between project
configurations.)
Added new types and internal functions for CIE RGB end point handling to
pngpriv.h (functions yet to be implemented).
Version 1.5.5beta06 [August 26, 2011]
Ensure the CMAKE_LIBRARY_OUTPUT_DIRECTORY is set in CMakeLists.txt
(Clifford Yap)
Fixes to rgb_to_gray and cHRM XYZ APIs (John Bowler):
The rgb_to_gray code had errors when combined with gamma correction.
Some pixels were treated as true grey when they weren't and such pixels
and true grey ones were not gamma corrected (the original value of the
red component was used instead). APIs to get and set cHRM using color
space end points have been added and the rgb_to_gray code that defaults
based on cHRM, and the divide-by-zero bug in png_handle_cHRM (CERT
VU#477046, CVE-2011-3328, introduced in 1.5.4) have been corrected.
A considerable number of tests has been added to pngvalid for the
rgb_to_gray transform.
Arithmetic errors in rgb_to_gray whereby the calculated gray value was
truncated to the bit depth rather than rounded have been fixed except in
the 8-bit non-gamma-corrected case (where consistency seems more important
than correctness.) The code still has considerable inaccuracies in the
8-bit case because 8-bit linear arithmetic is used.
Version 1.5.5beta07 [September 7, 2011]
Added "$(ARCH)" option to makefile.darwin
Added SunOS support to configure.ac and Makefile.am
Changed png_chunk_benign_error() to png_warning() in png.c, in
png_XYZ_from_xy_checked().
Version 1.5.5beta08 [September 10, 2011]
Fixed 64-bit compilation errors (gcc). The errors fixed relate
to conditions where types that are 32 bits in the GCC 32-bit
world (uLong and png_size_t) become 64 bits in the 64-bit
world. This produces potential truncation errors which the
compiler correctly flags.
Relocated new HAVE_SOLARIS_LD definition in configure.ac
Constant changes for 64-bit compatibility (removal of L suffixes). The
16-bit cases still use "L" as we don't have a 16-bit test system.
Version 1.5.5rc01 [September 15, 2011]
Removed "L" suffixes in pngpriv.h
Version 1.5.5 [September 22, 2011]
No changes.
Version 1.5.6beta01 [September 22, 2011]
Fixed some 64-bit type conversion warnings in pngrtran.c
Moved row_info from png_struct to a local variable.
The various interlace mask arrays have been made into arrays of
bytes and made PNG_CONST and static (previously some arrays were
marked PNG_CONST and some weren't).
Additional checks have been added to the transform code to validate the
pixel depths after the transforms on both read and write.
Removed some redundant code from pngwrite.c, in png_destroy_write_struct().
Changed chunk reading/writing code to use png_uint_32 instead of png_byte[4].
This removes the need to allocate temporary strings for chunk names on
the stack in the read/write code. Unknown chunk handling still uses the
string form because this is exposed in the API.
Version 1.5.6beta02 [September 26, 2011]
Added a note in the manual the png_read_update_info() must be called only
once with a particular info_ptr.
Fixed a typo in the definition of the new PNG_STRING_FROM_CHUNK(s,c) macro.
Version 1.5.6beta03 [September 28, 2011]
Revised test-pngtest.sh to report FAIL when pngtest fails.
Added "--strict" option to pngtest, to report FAIL when the failure is
only because the resulting valid files are different.
Revised CMakeLists.txt to work with mingw and removed some material from
CMakeLists.txt that is no longer useful in libpng-1.5.
Version 1.5.6beta04 [October 5, 2011]
Fixed typo in Makefile.in and Makefile.am ("-M Wl" should be "-M -Wl")."
Version 1.5.6beta05 [October 12, 2011]
Speed up png_combine_row() for interlaced images. This reduces the generality
of the code, allowing it to be optimized for Adam7 interlace. The masks
passed to png_combine_row() are now generated internally, avoiding
some code duplication and localizing the interlace handling somewhat.
Align png_struct::row_buf - previously it was always unaligned, caused by
a bug in the code that attempted to align it; the code needs to subtract
one from the pointer to take account of the filter byte prepended to
each row.
Optimized png_combine_row() when rows are aligned. This gains a small
percentage for 16-bit and 32-bit pixels in the typical case where the
output row buffers are appropriately aligned. The optimization was not
previously possible because the png_struct buffer was always misaligned.
Fixed bug in png_write_chunk_header() debug print, introduced in 1.5.6beta01.
Version 1.5.6beta06 [October 17, 2011]
Removed two redundant tests for uninitialized row.
Fixed a relatively harmless memory overwrite in compressed text writing
with a 1 byte zlib buffer.
Add ability to call png_read_update_info multiple times to pngvalid.c.
Fixes for multiple calls to png_read_update_info. These fixes attend to
most of the errors revealed in pngvalid, however doing the gamma work
twice results in inaccuracies that can't be easily fixed. There is now
a warning in the code if this is going to happen.
Turned on multiple png_read_update_info in pngvalid transform tests.
Prevent libpng from overwriting unused bits at the end of the image when
it is not byte aligned, while reading. Prior to libpng-1.5.6 libpng would
overwrite the partial byte at the end of each row if the row width was not
an exact multiple of 8 bits and the image is not interlaced.
Version 1.5.6beta07 [October 21, 2011]
Made png_ptr->prev_row an aligned pointer into png_ptr->big_prev_row
(Mans Rullgard).
Version 1.5.6rc01 [October 26, 2011]
Changed misleading "Missing PLTE before cHRM" warning to "Out of place cHRM"
Version 1.5.6rc02 [October 27, 2011]
Added LSR() macro to defend against buggy compilers that evaluate non-taken
code branches and complain about out-of-range shifts.
Version 1.5.6rc03 [October 28, 2011]
Renamed the LSR() macro to PNG_LSR() and added PNG_LSL() macro.
Fixed compiler warnings with Intel and MSYS compilers. The logical shift
fix for Microsoft Visual C is required by other compilers, so this
enables that fix for all compilers when using compile-time constants.
Under MSYS 'byte' is a name declared in a system header file, so we
changed the name of a local variable to avoid the warnings that result.
Added #define PNG_ALIGN_TYPE PNG_ALIGN_NONE to contrib/pngminim/*/pngusr.h
Version 1.5.6 [November 3, 2011]
No changes.
Version 1.5.7beta01 [November 4, 2011]
Added support for ARM processor, when decoding all PNG up-filtered rows
and any other-filtered rows with 3 or 4 bytes per pixel (Mans Rullgard).
Fixed bug in pngvalid on early allocation failure; fixed type cast in
pngmem.c; pngvalid would attempt to call png_error() if the allocation
of a png_struct or png_info failed. This would probably have led to a
crash. The pngmem.c implementation of png_malloc() included a cast
to png_size_t which would fail on large allocations on 16-bit systems.
Fix for the preprocessor of the Intel C compiler. The preprocessor
splits adjacent @ signs with a space; this changes the concatenation
token from @-@-@ to PNG_JOIN; that should work with all compiler
preprocessors.
Paeth filter speed improvements from work by Siarhei Siamashka. This
changes the 'Paeth' reconstruction function to improve the GCC code
generation on x86. The changes are only part of the suggested ones;
just the changes that definitely improve speed and remain simple.
The changes also slightly increase the clarity of the code.
Version 1.5.7beta02 [November 11, 2011]
Check compression_type parameter in png_get_iCCP and remove spurious
casts. The compression_type parameter is always assigned to, so must
be non-NULL. The cast of the profile length potentially truncated the
value unnecessarily on a 16-bit int system, so the cast of the (byte)
compression type to (int) is specified by ANSI-C anyway.
Fixed FP division by zero in pngvalid.c; the 'test_pixel' code left
the sBIT fields in the test pixel as 0, which resulted in a floating
point division by zero which was irrelevant but causes systems where
FP exceptions cause a crash. Added code to pngvalid to turn on FP
exceptions if the appropriate glibc support is there to ensure this is
tested in the future.
Updated scripts/pnglibconf.mak and scripts/makefile.std to handle the
new PNG_JOIN macro.
Added versioning to pnglibconf.h comments.
Simplified read/write API initial version; basic read/write tested on
a variety of images, limited documentation (in the header file.)
Installed more accurate linear to sRGB conversion tables. The slightly
modified tables reduce the number of 16-bit values that
convert to an off-by-one 8-bit value. The "makesRGB.c" code that was used
to generate the tables is now in a contrib/sRGBtables sub-directory.
Version 1.5.7beta03 [November 17, 2011]
Removed PNG_CONST from the sRGB table declarations in pngpriv.h and png.c
Added run-time detection of NEON support.
Added contrib/libtests; includes simplified API test and timing test and
a color conversion utility for rapid checking of failed 'pngstest' results.
Multiple transform bug fixes plus a work-round for double gamma correction.
libpng does not support more than one transform that requires linear data
at once - if this is tried typically the results is double gamma
correction. Since the simplified APIs can need rgb to gray combined with
a compose operation it is necessary to do one of these outside the main
libpng transform code. This check-in also contains fixes to various bugs
in the simplified APIs themselves and to some bugs in compose and rgb to
gray (on palette) itself.
Fixes for C++ compilation using g++ When libpng source is compiled
using g++. The compiler imposes C++ rules on the C source; thus it
is desirable to make the source work with either C or C++ rules
without throwing away useful error information. This change adds
png_voidcast to allow C semantic (void*) cases or the corresponding
C++ static_cast operation, as appropriate.
Added --noexecstack to assembler file compilation. GCC does not set
this on assembler compilation, even though it does on C compilation.
This creates security issues if assembler code is enabled; the
work-around is to set it by default in the flags for $(CCAS)
Work around compilers that don't support declaration of const data. Some
compilers fault 'extern const' data declarations (because the data is
not initialized); this turns on const-ness only for compilers where
this is known to work.
Version 1.5.7beta04 [November 17, 2011]
Since the gcc driver does not recognize the --noexecstack flag, we must
use the -Wa prefix to have it passed through to the assembler.
Also removed a duplicate setting of this flag.
Added files that were omitted from the libpng-1.5.7beta03 zip distribution.
Version 1.5.7beta05 [November 25, 2011]
Removed "zTXt" from warning in generic chunk decompression function.
Validate time settings passed to png_set_tIME() and png_convert_to_rfc1123()
(Frank Busse). Note: This prevented CVE-2015-7981 from affecting
libpng-1.5.7 and later.
Added MINGW support to CMakeLists.txt
Reject invalid compression flag or method when reading the iTXt chunk.
Backed out 'simplified' API changes. The API seems too complex and there
is a lack of consensus or enthusiasm for the proposals. The API also
reveals significant bugs inside libpng (double gamma correction and the
known bug of being unable to retrieve a corrected palette). It seems
better to wait until the bugs, at least, are corrected.
Moved pngvalid.c into contrib/libtests
Rebuilt Makefile.in, configure, etc., with autoconf-2.68
Version 1.5.7rc01 [December 1, 2011]
Replaced an "#if" with "#ifdef" in pngrtran.c
Revised #if PNG_DO_BC block in png.c (use #ifdef and add #else)
Version 1.5.7rc02 [December 5, 2011]
Revised project files and contrib/pngvalid/pngvalid.c to account for
the relocation of pngvalid into contrib/libtests.
Revised pngconf.h to use " __declspec(restrict)" only when MSC_VER >= 1400,
as in libpng-1.5.4.
Put CRLF line endings in the owatcom project files.
Version 1.5.7rc03 [December 7, 2011]
Updated CMakeLists.txt to account for the relocation of pngvalid.c
Version 1.5.7 [December 15, 2011]
Minor fixes to pngvalid.c for gcc 4.6.2 compatibility to remove warnings
reported by earlier versions.
Fixed minor memset/sizeof errors in pngvalid.c.
Version 1.6.0beta01 [December 15, 2011]
Removed machine-generated configure files from the GIT repository (they will
continue to appear in the tarball distributions and in the libpng15 and
earlier GIT branches).
Restored the new 'simplified' API, which was started in libpng-1.5.7beta02
but later deleted from libpng-1.5.7beta05.
Added example programs for the new 'simplified' API.
Added ANSI-C (C90) headers and require them, and take advantage of the
change. Also fixed some of the projects/* and contrib/* files that needed
updates for libpng16 and the move of pngvalid.c.
With this change the required ANSI-C header files are assumed to exist: the
implementation must provide float.h, limits.h, stdarg.h and stddef.h and
libpng relies on limits.h and stddef.h existing and behaving as defined
(the other two required headers aren't used). Non-ANSI systems that don't
have stddef.h or limits.h will have to provide an appropriate fake
containing the relevant types and #defines.
Dropped support for 16-bit platforms. The use of FAR/far has been eliminated
and the definition of png_alloc_size_t is now controlled by a flag so
that 'small size_t' systems can select it if necessary. Libpng 1.6 may
not currently work on such systems -- it seems likely that it will
ask 'malloc' for more than 65535 bytes with any image that has a
sufficiently large row size (rather than simply failing to read such
images).
New tools directory containing tools used to generate libpng code.
Fixed race conditions in parallel make builds. With higher degrees of
parallelism during 'make' the use of the same temporary file names such
as 'dfn*' can result in a race where a temporary file from one arm of the
build is deleted or overwritten in another arm. This changes the
temporary files for suffix rules to always use $* and ensures that the
non-suffix rules use unique file names.
Version 1.6.0beta02 [December 21, 2011]
Correct configure builds where build and source directories are separate.
The include path of 'config.h' was erroneously made relative in pngvalid.c
in libpng 1.5.7.
Version 1.6.0beta03 [December 22, 2011]
Start-up code size improvements, error handler flexibility. These changes
alter how the tricky allocation of the initial png_struct and png_info
structures are handled. png_info is now handled in pretty much the same
way as everything else, except that the allocations handle NULL return
silently. png_struct is changed in a similar way on allocation and on
deallocation a 'safety' error handler is put in place (which should never
be required). The error handler itself is changed to permit mismatches
in the application and libpng error buffer size; however, this means a
silent change to the API to return the jmp_buf if the size doesn't match
the size from the libpng compilation; libpng now allocates the memory and
this may fail. Overall these changes result in slight code size
reductions; however, this is a reduction in code that is always executed
so is particularly valuable. Overall on a 64-bit system the libpng DLL
decreases in code size by 1733 bytes. pngerror.o increases in size by
about 465 bytes because of the new functionality.
Added png_convert_to_rfc1123_buffer() and deprecated png_convert_to_rfc1123()
to avoid including a spurious buffer in the png_struct.
Version 1.6.0beta04 [December 30, 2011]
Regenerated configure scripts with automake-1.11.2
Eliminated png_info_destroy(). It is now used only in png.c and only calls
one other internal function and memset().
Enabled png_get_sCAL_fixed() if floating point APIs are enabled. Previously
it was disabled whenever internal fixed point arithmetic was selected,
which meant it didn't exist even on systems where FP was available but not
preferred.
Added pngvalid.c compile time checks for const APIs.
Implemented 'restrict' for png_info and png_struct. Because of the way
libpng works both png_info and png_struct are always accessed via a
single pointer. This means adding C99 'restrict' to the pointer gives
the compiler some opportunity to optimize the code. This change allows
that.
Moved AC_MSG_CHECKING([if libraries can be versioned]) later to the proper
location in configure.ac (Gilles Espinasse).
Changed png_memcpy to C assignment where appropriate. Changed all those
uses of png_memcpy that were doing a simple assignment to assignments
(all those cases where the thing being copied is a non-array C L-value).
Added some error checking to png_set_*() routines.
Removed the reference to the non-exported function png_memcpy() from
example.c.
Fixed the Visual C 64-bit build - it requires jmp_buf to be aligned, but
it had become misaligned.
Revised contrib/pngminus/pnm2png.c to avoid warnings when png_uint_32
and unsigned long are of different sizes.
Version 1.6.0beta05 [January 15, 2012]
Updated manual with description of the simplified API (copied from png.h)
Fix bug in pngerror.c: some long warnings were being improperly truncated
(CVE-2011-3464, bug introduced in libpng-1.5.3beta05).
Version 1.6.0beta06 [January 24, 2012]
Added palette support to the simplified APIs. This commit
changes some of the macro definitions in png.h, app code
may need corresponding changes.
Increased the formatted warning buffer to 192 bytes.
Added color-map support to simplified API. This is an initial version for
review; the documentation has not yet been updated.
Fixed Min/GW uninstall to remove libpng.dll.a
Version 1.6.0beta07 [January 28, 2012]
Eliminated Intel icc/icl compiler warnings. The Intel (GCC derived)
compiler issues slightly different warnings from those issued by the
current vesions of GCC. This eliminates those warnings by
adding/removing casts and small code rewrites.
Updated configure.ac from autoupdate: added --enable-werror option.
Also some layout regularization and removal of introduced tab characters
(replaced with 3-character indentation). Obsolete macros identified by
autoupdate have been removed; the replacements are all in 2.59 so
the pre-req hasn't been changed. --enable-werror checks for support
for -Werror (or the given argument) in the compiler. This mimics the
gcc configure option by allowing -Werror to be turned on safely; without
the option the tests written in configure itself fail compilation because
they cause compiler warnings.
Rewrote autogen.sh to run autoreconf instead of running tools one-by-one.
Conditionalize the install rules for MINGW and CYGWIN in CMakeLists.txt and
set CMAKE_LIBRARY_OUTPUT_DIRECTORY to "lib" on all platforms (C. Yapp).
Freeze libtool files in the 'scripts' directory. This version of autogen.sh
attempts to dissuade people from running it when it is not, or should not,
be necessary. In fact, autogen.sh does not work when run in a libpng
directory extracted from a tar distribution anymore. You must run it in
a GIT clone instead.
Added two images to contrib/pngsuite (1-bit and 2-bit transparent grayscale),
and renamed three whose names were inconsistent with those in
pngsuite/README.txt.
Version 1.6.0beta08 [February 1, 2012]
Fixed Image::colormap misalignment in pngstest.c
Check libtool/libtoolize version number (2.4.2) in configure.ac
Divide test-pngstest.sh into separate pngstest runs for basic and
transparent images.
Moved automake options to AM_INIT_AUTOMAKE in configure.ac
Added color-tests, silent-rules (Not yet implemented in Makefile.am) and
version checking to configure.ac
Improved pngstest speed by not doing redundant tests and add const to
the background parameter of png_image_finish_read. The --background
option is now done automagically only when required, so that commandline
option no longer exists.
Cleaned up pngpriv.h to consistently declare all functions and data.
Also eliminated PNG_CONST_DATA, which is apparently not needed but we
can't be sure until it is gone.
Added symbol prefixing that allows all the libpng external symbols
to be prefixed (suggested by Reuben Hawkins).
Updated "ftbb*.png" list in the owatcom and vstudio projects.
Fixed 'prefix' builds on clean systems. The generation of pngprefix.h
should not require itself.
Updated INSTALL to explain that autogen.sh must be run in a GIT clone,
not in a libpng directory extracted from a tar distribution.
Version 1.6.0beta09 [February 1, 2012]
Reverted the prebuilt configure files to libpng-1.6.0beta05 condition.
Version 1.6.0beta10 [February 3, 2012]
Added Z_SOLO for zlib-1.2.6+ and correct pngstest tests
Updated list of test images in CMakeLists.txt
Updated the prebuilt configure files to current condition.
Revised INSTALL information about autogen.sh; it works in tar distributions.
Version 1.6.0beta11 [February 16, 2012]
Fix character count in pngstest command in projects/owatcom/pngstest.tgt
Revised test-pngstest.sh to report PASS/FAIL for each image.
Updated documentation about the simplified API.
Corrected estimate of error in libpng png_set_rgb_to_gray API. The API is
extremely inaccurate for sRGB conversions because it uses an 8-bit
intermediate linear value and it does not use the sRGB transform, so it
suffers from the known instability in gamma transforms for values close
to 0 (see Poynton). The net result is that the calculation has a maximum
error of 14.99/255; 0.5/255^(1/2.2). pngstest now uses 15 for the
permitted 8-bit error. This may still not be enough because of arithmetic
error.
Removed some unused arrays (with #ifdef) from png_read_push_finish_row().
Fixed a memory overwrite bug in simplified read of RGB PNG with
non-linear gamma Also bugs in the error checking in pngread.c and changed
quite a lot of the checks in pngstest.c to be correct; either correctly
written or not over-optimistic. The pngstest changes are insufficient to
allow all possible RGB transforms to be passed; pngstest cmppixel needs
to be rewritten to make it clearer which errors it allows and then changed
to permit known inaccuracies.
Removed tests for no-longer-used *_EMPTY_PLTE_SUPPORTED from pngstruct.h
Fixed fixed/float API export conditionals. 1) If FIXED_POINT or
FLOATING_POINT options were switched off, png.h ended up with lone ';'
characters. This is not valid ANSI-C outside a function. The ';'
characters have been moved inside the definition of PNG_FP_EXPORT and
PNG_FIXED_EXPORT. 2) If either option was switched off, the declaration
of the corresponding functions were completely omitted, even though some
of them are still used internally. The result is still valid, but
produces warnings from gcc with some warning options (including -Wall). The
fix is to cause png.h to declare the functions with PNG_INTERNAL_FUNCTION
when png.h is included from pngpriv.h.
Check for invalid palette index while reading paletted PNG. When one is
found, issue a warning and increase png_ptr->num_palette accordingly.
Apps are responsible for checking to see if that happened.
Version 1.6.0beta12 [February 18, 2012]
Do not increase num_palette on invalid_index.
Relocated check for invalid palette index to pngrtran.c, after unpacking
the sub-8-bit pixels.
Fixed CVE-2011-3026 buffer overrun bug. This bug was introduced when
iCCP chunk support was added at libpng-1.0.6. Deal more correctly with the
test on iCCP chunk length. Also removed spurious casts that may hide
problems on 16-bit systems.
Version 1.6.0beta13 [February 24, 2012]
Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from
pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c;
now that png_ptr->buffer is inaccessible to applications, the special
handling is no longer useful.
Added PNG_SAFE_LIMITS feature to pnglibconf.dfa, pngpriv.h, and new
pngusr.dfa to reset the user limits to safe ones if PNG_SAFE_LIMITS is
defined. To enable, use "CPPFLAGS=-DPNG_SAFE_LIMITS_SUPPORTED=1" on the
configure command or put #define PNG_SAFE_LIMITS_SUPPORTED in
pnglibconf.h.prebuilt and pnglibconf.h.
Version 1.6.0beta14 [February 27, 2012]
Added information about the new limits in the manual.
Updated Makefile.in
Version 1.6.0beta15 [March 2, 2012]
Removed unused "current_text" members of png_struct and the png_free()
of png_ptr->current_text from pngread.c
Rewrote pngstest.c for substantial speed improvement.
Fixed transparent pixel and 16-bit rgb tests in pngstest and removed a
spurious check in pngwrite.c
Added PNG_IMAGE_FLAG_FAST for the benefit of applications that store
intermediate files, or intermediate in-memory data, while processing
image data with the simplified API. The option makes the files larger
but faster to write and read. pngstest now uses this by default; this
can be disabled with the --slow option.
Improved pngstest fine tuning of error numbers, new test file generator.
The generator generates images that test the full range of sample values,
allow the error numbers in pngstest to be tuned and checked. makepng
also allows generation of images with extra chunks, although this is
still work-in-progress.
Added check for invalid palette index while reading.
Fixed some bugs in ICC profile writing. The code should now accept
all potentially valid ICC profiles and reject obviously invalid ones.
It now uses png_error() to do so rather than casually writing a PNG
without the necessary color data.
Removed whitespace from the end of lines in all source files and scripts.
Version 1.6.0beta16 [March 6, 2012]
Relocated palette-index checking function from pngrutil.c to pngtrans.c
Added palette-index checking while writing.
Changed png_inflate() and calling routines to avoid overflow problems.
This is an intermediate check-in that solves the immediate problems and
introduces one performance improvement (avoiding a copy via png_ptr->zbuf.)
Further changes will be made to make ICC profile handling more secure.
Fixed build warnings (MSVC, GCC, GCC v3). Cygwin GCC with default options
declares 'index' as a global, causing a warning if it is used as a local
variable. GCC 64-bit warns about assigning a (size_t) (unsigned 64-bit)
to an (int) (signed 32-bit). MSVC, however, warns about using the
unary '-' operator on an unsigned value (even though it is well defined
by ANSI-C to be ~x+1). The padding calculation was changed to use a
different method. Removed the tests on png_ptr->pass.
Added contrib/libtests/tarith.c to test internal arithmetic functions from
png.c. This is a libpng maintainer program used to validate changes to the
internal arithmetic functions.
Made read 'inflate' handling like write 'deflate' handling. The read
code now claims and releases png_ptr->zstream, like the write code.
The bug whereby the progressive reader failed to release the zstream
is now fixed, all initialization is delayed, and the code checks for
changed parameters on deflate rather than always calling
deflatedEnd/deflateInit.
Validate the zTXt strings in pngvalid.
Added code to validate the windowBits value passed to deflateInit2().
If the call to deflateInit2() is wrong a png_warning will be issued
(in fact this is harmless, but the PNG data produced may be sub-optimal).
Version 1.6.0beta17 [March 10, 2012]
Fixed PNG_LIBPNG_BUILD_BASE_TYPE definition.
Reject all iCCP chunks after the first, even if the first one is invalid.
Deflate/inflate was reworked to move common zlib calls into single
functions [rw]util.c. A new shared keyword check routine was also added
and the 'zbuf' is no longer allocated on progressive read. It is now
possible to call png_inflate() incrementally. A warning is no longer
issued if the language tag or translated keyword in the iTXt chunk
has zero length.
If benign errors are disabled use maximum window on ancillary inflate.
This works round a bug introduced in 1.5.4 where compressed ancillary
chunks could end up with a too-small windowBits value in the deflate
header.
Version 1.6.0beta18 [March 16, 2012]
Issue a png_benign_error() instead of png_warning() about bad palette index.
In pngtest, treat benign errors as errors if "-strict" is present.
Fixed an off-by-one error in the palette index checking function.
Fixed a compiler warning under Cygwin (Windows-7, 32-bit system)
Revised example.c to put text strings in a temporary character array
instead of directly assigning string constants to png_textp members.
This avoids compiler warnings when -Wwrite-strings is enabled.
Added output flushing to aid debugging under Visual Studio. Unfortunately
this is necessary because the VS2010 output window otherwise simply loses
the error messages on error (they weren't flushed to the window before
the process exited, apparently!)
Added configuration support for benign errors and changed the read
default. Also changed some warnings in the iCCP and sRGB handling
from to benign errors. Configuration now makes read benign
errors warnings and write benign errors to errors by default (thus
changing the behavior on read). The simplified API always forces
read benign errors to warnings (regardless of the system default, unless
this is disabled in which case the simplified API can't be built.)
Version 1.6.0beta19 [March 18, 2012]
Work around for duplicate row start calls; added warning messages.
This turns on PNG_FLAG_DETECT_UNINITIALIZED to detect app code that
fails to call one of the 'start' routines (not enabled in libpng-1.5
because it is technically an API change, since it did normally work
before.) It also makes duplicate calls to png_read_start_row (an
internal function called at the start of the image read) benign, as
they were before changes to use png_inflate_claim. Somehow webkit is
causing this to happen; this is probably a mis-feature in the zlib
changes so this commit is only a work-round.
Removed erroneous setting of DETECT_UNINITIALIZED and added more
checks. The code now does a png_error if an attempt is made to do the
row initialization twice; this is an application error and it has
serious consequences because the transform data in png_struct is
changed by each call.
Added application error reporting and added chunk names to read
benign errors; also added --strict to pngstest - not enabled
yet because a warning is produced.
Avoid the double gamma correction warning in the simplified API.
This allows the --strict option to pass in the pngstest checks
Version 1.6.0beta20 [March 29, 2012]
Changed chunk handler warnings into benign errors, incrementally load iCCP
Added checksum-icc.c to contrib/tools
Prevent PNG_EXPAND+PNG_SHIFT doing the shift twice.
Recognize known sRGB ICC profiles while reading; prefer writing the
iCCP profile over writing the sRGB chunk, controlled by the
PNG_sRGB_PROFILE_CHECKS option.
Revised png_set_text_2() to avoid potential memory corruption (fixes
CVE-2011-3048, also known as CVE-2012-3425).
Version 1.6.0beta21 [April 27, 2012]
Revised scripts/makefile.darwin: use system zlib; remove quotes around
architecture list; add missing ppc architecture; add architecture options
to shared library link; don't try to create a shared lib based on missing
RELEASE variable.
Enable png_set_check_for_invalid_index() for both read and write.
Removed #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED in pngpriv.h around
declaration of png_handle_unknown().
Added -lssp_nonshared in a comment in scripts/makefile.freebsd
and changed deprecated NOOBJ and NOPROFILE to NO_OBJ and NO_PROFILE.
Version 1.6.0beta22 [May 23, 2012]
Removed need for -Wno-cast-align with clang. clang correctly warns on
alignment increasing pointer casts when -Wcast-align is passed. This
fixes the cases that clang warns about either by eliminating the
casts from png_bytep to png_uint_16p (pngread.c), or, for pngrutil.c
where the cast is previously verified or pngstest.c where it is OK, by
introducing new png_aligncast macros to do the cast in a way that clang
accepts.
Version 1.6.0beta23 [June 6, 2012]
Revised CMakeLists.txt to not attempt to make a symlink under mingw.
Made fixes for new optimization warnings from gcc 4.7.0. The compiler
performs an optimization which is safe; however it then warns about it.
Changing the type of 'palette_number' in pngvalid.c removes the warning.
Do not depend upon a GCC feature macro being available for use in generating
the linker mapfile symbol prefix.
Improved performance of new do_check_palette_indexes() function (only
update the value when it actually increases, move test for whether
the check is wanted out of the function.
Version 1.6.0beta24 [June 7, 2012]
Don't check palette indexes if num_palette is 0 (as it can be in MNG files).
Version 1.6.0beta25 [June 16, 2012]
Revised png_set_keep_unknown_chunks() so num_chunks < 0 means ignore all
unknown chunks and all known chunks except for IHDR, PLTE, tRNS, IDAT,
and IEND. Previously it only meant ignore all unknown chunks, the
same as num_chunks == 0. Revised png_image_skip_unused_chunks() to
provide a list of chunks to be processed instead of a list of chunks to
ignore. Revised contrib/gregbook/readpng2.c accordingly.
Version 1.6.0beta26 [July 10, 2012]
Removed scripts/makefile.cegcc from the *.zip and *.7z distributions; it
depends on configure, which is not included in those archives.
Moved scripts/chkfmt to contrib/tools.
Changed "a+w" to "u+w" in Makefile.in to fix CVE-2012-3386.
Version 1.6.0beta27 [August 11, 2012]
Do not compile PNG_DEPRECATED, PNG_ALLOC and PNG_PRIVATE when __GNUC__ < 3.
Do not use __restrict when GNUC is <= 3.1
Removed references to png_zalloc() and png_zfree() from the manual.
Fixed configurations where floating point is completely disabled. Because
of the changes to support symbol prefixing PNG_INTERNAL_FUNCTION declares
floating point APIs during libpng builds even if they are completely
disabled. This requires the png floating point types (png_double*) to be
declared even though the functions are never actually defined. This
change provides a dummy definition so that the declarations work, yet any
implementation will fail to compile because of an incomplete type.
Re-eliminated the use of strcpy() in pngtest.c. An unnecessary use of
strcpy() was accidentally re-introduced in libpng16; this change replaces
it with strncpy().
Eliminated use of png_sizeof(); use sizeof() instead.
Use a consistent style for (sizeof type) and (sizeof (array))
Cleanup of png_set_filler(). This function does very different things on
read and write. In libpng 1.6 the two cases can be distinguished and
considerable code cleanup, and extra error checking, is possible. This
makes calls on the write side that have no effect be ignored with a
png_app_error(), which can be disabled in the app using
png_set_benign_errors(), and removes the spurious use of usr_channels
on the read side.
Insist on autotools 1.12.1 for git builds because there are security issues
with 1.12 and insisting on anything less would allow 1.12 to be used.
Removed info_ptr->signature[8] from WRITE-only builds.
Add some conditions for compiling png_fixed(). This is a small function
but it requires "-lm" on some platforms.
Cause pngtest --strict to fail on any warning from libpng (not just errors)
and cause it not to fail at the comparison step if libpng lacks support
for writing chunks that it reads from the input (currently only implemented
for compressed text chunks).
Make all three "make check" test programs work without READ or WRITE support.
Now "make check" will succeed even if libpng is compiled with -DPNG_NO_READ
or -DPNG_NO_WRITE. The tests performed are reduced, but the basic reading
and writing of a PNG file is always tested by one or more of the tests.
Consistently use strlen(), memset(), memcpy(), and memcmp() instead of the
png_strlen(), png_memset(), png_memcpy(), and png_memcmp() macros.
Removed the png_sizeof(), png_strlen(), png_memset(), png_memcpy(), and
png_memcmp() macros.
Work around gcc 3.x and Microsoft Visual Studio 2010 complaints. Both object
to the split initialization of num_chunks.
Version 1.6.0beta28 [August 29, 2012]
Unknown handling fixes and clean up. This adds more correct option
control of the unknown handling, corrects the pre-existing bug where
the per-chunk 'keep' setting is ignored and makes it possible to skip
IDAT chunks in the sequential reader (broken in earlier 1.6 versions).
There is a new test program, test-unknown.c, which is a work in progress
(not currently part of the test suite). Comments in the header files now
explain how the unknown handling works.
Allow fine grain control of unknown chunk APIs. This change allows
png_set_keep_unknown_chunks() to be turned off if not required and causes
both read and write to behave appropriately (on read this is only possible
if the user callback is used to handle unknown chunks). The change
also removes the support for storing unknown chunks in the info_struct
if the only unknown handling enabled is via the callback, allowing libpng
to be configured with callback reading and none of the unnecessary code.
Corrected fix for unknown handling in pngtest. This reinstates the
libpng handling of unknown chunks other than vpAg and sTER (including
unsafe-to-copy chunks which were dropped before) and eliminates the
repositioning of vpAg and sTER in pngtest.png by changing pngtest.png
(so the chunks are where libpng would put them).
Added "tunknown" test and corrected a logic error in png_handle_unknown()
when SAVE support is absent. Moved the shell test scripts for
contrib/libtests from the libpng top directory to contrib/libtests.
png_handle_unknown() must always read or skip the chunk, if
SAVE_UNKNOWN_CHUNKS is turned off *and* the application does not set
a user callback an unknown chunk will not be read, leading to a read
error, which was revealed by the "tunknown" test.
Cleaned up and corrected ICC profile handling.
contrib/libtests/makepng: corrected 'rgb' and 'gray' cases. profile_error
messages could be truncated; made a correct buffer size calculation and
adjusted pngerror.c appropriately. png_icc_check_* checking improved;
changed the functions to receive the correct color type of the PNG on read
or write and check that it matches the color space of the profile (despite
what the comments said before, there is danger in assuming the app will
cope correctly with an RGB profile on a grayscale image and, since it
violates the PNG spec, allowing it is certain to produce inconsistent
app behavior and might even cause app crashes.) Check that profiles
contain the tags needed to process the PNG (tags all required by the ICC
spec). Removed unused PNG_STATIC from pngpriv.h.
Version 1.6.0beta29 [September 4, 2012]
Fixed the simplified API example programs to add the *colormap parameter
to several of he API and improved the error message if the version field
is not set.
Added contrib/examples/* to the *.zip and *.7z distributions.
Updated simplified API synopses and description of the png_image structure
in the manual.
Made makepng and pngtest produce identical PNGs, add "--relaxed" option
to pngtest. The "--relaxed" option turns off the benign errors that are
enabled by default in pre-RC builds. makepng can now write ICC profiles
where the length has not been extended to a multiple of 4, and pngtest
now intercepts all libpng errors, allowing the previously-introduced
"--strict test" on no warnings to actually work.
Improved ICC profile handling including cHRM chunk generation and fixed
Cygwin+MSVC build errors. The ICC profile handling now includes more
checking. Several errors that caused rejection of the profile are now
handled with a warning in such a way that the invalid profiles will be
read by default in release (but not pre-RC) builds but will not be
written by default. The easy part of handling the cHRM chunk is written,
where the ICC profile contains the required data. The more difficult
part plus guessing a gAMA value requires code to pass selected RGB values
through the profile.
Version 1.6.0beta30 [October 24, 2012]
Changed ICC profile matrix/vector types to not depend on array type rules.
By the ANSI-C standard the new types should be identical to the previous
versions, and all known versions of gcc tested with the previous versions
except for GCC-4.2.1 work with this version. The change makes the ANSI-C
rule that const applied to an array of elements applies instead to the
elements in the array moot by explicitly applying const to the base
elements of the png_icc_matrix and png_icc_vector types. The accidental
(harmless) 'const' previously applied to the parameters of two of the
functions have also been removed.
Added a work around for GCC 4.2 optimization bug.
Marked the broken (bad white point) original HP sRGB profiles correctly and
correct comments.
Added -DZ_SOLO to contrib/pngminim/*/makefile to work with zlib-1.2.7
Use /MDd for vstudio debug builds. Also added pngunkown to the vstudio
builds, fixed build errors and corrected a minor exit code error in
pngvalid if the 'touch' file name is invalid.
Add updated WARNING file to projects/vstudio from libpng 1.5/vstudio
Fixed build when using #define PNG_NO_READ_GAMMA in png_do_compose() in
pngrtran.c (Domani Hannes).
Version 1.6.0beta31 [November 1, 2012]
Undid the erroneous change to vstudio/pngvalid build in libpng-1.6.0beta30.
Made pngvalid so that it will build outside the libpng source tree.
Made builds -DPNG_NO_READ_GAMMA compile (the unit tests still fail).
Made PNG_NO_READ_GAMMA switch off interfaces that depend on READ_GAMMA.
Prior to 1.6.0 switching off READ_GAMMA did unpredictable things to the
interfaces that use it (specifically, png_do_background in 1.4 would
simply display composite for grayscale images but do composition
with the incorrect arithmetic for color ones). In 1.6 the semantic
of -DPNG_NO_READ_GAMMA is changed to simply disable any interface that
depends on it; this obliges people who set it to consider whether they
really want it off if they happen to use any of the interfaces in
question (typically most users who disable it won't).
Fixed GUIDs in projects/vstudio. Some were duplicated or missing,
resulting in VS2010 having to update the files.
Removed non-working ICC profile support code that was mostly added to
libpng-1.6.0beta29 and beta30. There was too much code for too little
gain; implementing full ICC color correction may be desirable but is left
up to applications.
Version 1.6.0beta32 [November 25, 2012]
Fixed an intermittent SEGV in pngstest due to an uninitialized array element.
Added the ability for contrib/libtests/makepng.c to make a PNG with just one
color. This is useful for debugging pngstest color inaccuracy reports.
Fixed error checking in the simplified write API (Olaf van der Spek)
Made png_user_version_check() ok to use with libpng version 1.10.x and later.
Version 1.6.0beta33 [December 15, 2012]
Fixed typo in png.c (PNG_SET_CHUNK_MALLOC_MAX should be PNG_CHUNK_MALLOC_MAX)
that causes the MALLOC_MAX limit not to work (John Bowler)
Change png_warning() to png_app_error() in pngwrite.c and comment the
fall-through condition.
Change png_warning() to png_app_warning() in png_write_tRNS().
Rearranged the ARM-NEON optimizations: Isolated the machine specific code
to the hardware subdirectory and added comments to pngrutil.c so that
implementors of other optimizations know what to do.
Fixed cases of unquoted DESTDIR in Makefile.am
Rebuilt Makefile.in, etc., with autoconf-2.69 and automake-1.12.5.
Version 1.6.0beta34 [December 19, 2012]
Cleaned up whitespace in the synopsis portion of the manpage "libpng.3"
Disassembled the version number in scripts/options.awk (necessary for
building on SunOs).
Version 1.6.0beta35 [December 23, 2012]
Made default Zlib compression settings be configurable. This adds #defines to
pnglibconf.h to control the defaults.
Fixed Windows build issues, enabled ARM compilation. Various warnings issued
by earlier versions of GCC fixed for Cygwin and Min/GW (which both use old
GCCs.) ARM support is enabled by default in zlib.props (unsupported by
Microsoft) and ARM compilation is made possible by deleting the check for
x86. The test programs cannot be run because they are not signed.
Version 1.6.0beta36 [January 2, 2013]
Discontinued distributing libpng-1.x.x.tar.bz2.
Discontinued distributing libpng-1.7.0-1.6.0-diff.txt and similar.
Rebuilt configure with autoconf-2.69 (inadvertently not done in beta33)
Fixed 'make distcheck' on SUN OS - libpng.so was not being removed
Version 1.6.0beta37 [January 10, 2013]
Fixed conceivable but difficult to repro overflow. Also added two test
programs to generate and test a PNG which should have the problem.
Version 1.6.0beta39 [January 19, 2013]
Again corrected attempt at overflow detection in png_set_unknown_chunks()
(CVE-2013-7353). Added overflow detection in png_set_sPLT() and
png_set_text_2() (CVE-2013-7354).
Version 1.6.0beta40 [January 20, 2013]
Use consistent handling of overflows in text, sPLT and unknown png_set_* APIs
Version 1.6.0rc01 [January 26, 2013]
No changes.
Version 1.6.0rc02 [February 4, 2013]
Added png_get_palette_max() function.
Version 1.6.0rc03 [February 5, 2013]
Fixed the png_get_palette_max API.
Version 1.6.0rc04 [February 7, 2013]
Turn serial tests back on (recently turned off by autotools upgrade).
Version 1.6.0rc05 [February 8, 2013]
Update manual about png_get_palette_max().
Version 1.6.0rc06 [February 9, 2013]
Fixed missing dependency in --prefix builds The intermediate
internal 'prefix.h' file can only be generated correctly after
pnglibconf.h, however the dependency was not in Makefile.am. The
symptoms are unpredictable depending on the order make chooses to
build pngprefix.h and pnglibconf.h, often the error goes unnoticed
because there is a system pnglibconf.h to use instead.
Version 1.6.0rc07 [February 10, 2013]
Enclosed the new png_get_palette_max in #ifdef PNG_GET_PALETTE_MAX_SUPPORTED
block, and revised pnglibconf.h and pnglibconf.h.prebuilt accordingly.
Version 1.6.0rc08 [February 10, 2013]
Fix typo in png.h #ifdef
Version 1.6.0 [February 14, 2013]
No changes.
Version 1.6.1beta01 [February 16, 2013]
Made symbol prefixing work with the ARM neon optimizations. Also allow
pngpriv.h to be included for preprocessor definitions only, so it can
be used in non-C/C++ files. Back ported from libpng 1.7.
Made sRGB check numbers consistent.
Ported libpng 1.5 options.awk/dfn file handling to 1.6, fixed one bug.
Removed cc -E workround, corrected png_get_palette_max API Tested on
SUN OS cc 5.9, which demonstrates the tokenization problem previously
avoided by using /lib/cpp. Since all .dfn output is now protected in
double quotes unless it is to be macro substituted the fix should
work everywhere.
Enabled parallel tests - back ported from libpng-1.7.
scripts/pnglibconf.dfa formatting improvements back ported from libpng17.
Fixed a race condition in the creation of the build 'scripts' directory
while building with a parallel make.
Use approved/supported Android method to check for NEON, use Linux/POSIX
1003.1 API to check /proc/self/auxv avoiding buffer allocation and other
library calls (ported from libpng15).
Version 1.6.1beta02 [February 19, 2013]
Use parentheses more consistently in "#if defined(MACRO)" tests.
Folded long lines.
Reenabled code to allow zero length PLTE chunks for MNG.
Version 1.6.1beta03 [February 22, 2013]
Fixed ALIGNED_MEMORY support.
Added a new configure option:
--enable-arm-neon=always will stop the run-time checks. New checks
within arm/arm_init.c will cause the code not to be compiled unless
__ARM_NEON__ is set. This should make it fail safe (if someone asks
for it on then the build will fail if it can't be done.)
Updated the INSTALL document.
Version 1.6.1beta04 [February 27, 2013]
Revised INSTALL to recommend using CPPFLAGS instead of INCLUDES.
Revised scripts/makefile.freebsd to respect ZLIBLIB and ZLIBINC.
Revised scripts/dfn.awk to work with the buggy MSYS awk that has trouble
with CRLF line endings.
Version 1.6.1beta05 [March 1, 2013]
Avoid a possible memory leak in contrib/gregbook/readpng.c
Version 1.6.1beta06 [March 4, 2013]
Better documentation of unknown handling API interactions.
Corrected Android builds and corrected libpng.vers with symbol
prefixing. It also makes those tests compile and link on Android.
Added an API png_set_option() to set optimization options externally,
providing an alternative and general solution for the non-portable
run-time tests used by the ARM Neon code, using the PNG_ARM_NEON option.
The order of settings vs options in pnglibconf.h is reversed to allow
settings to depend on options and options can now set (or override) the
defaults for settings.
Version 1.6.1beta07 [March 7, 2013]
Corrected simplified API default gamma for color-mapped output, added
a flag to change default. In 1.6.0 when the simplified API was used
to produce color-mapped output from an input image with no gamma
information the gamma assumed for the input could be different from
that assumed for non-color-mapped output. In particular 16-bit depth
input files were assumed to be sRGB encoded, whereas in the 'direct'
case they were assumed to have linear data. This was an error. The
fix makes the simplified API treat all input files the same way and
adds a new flag to the png_image::flags member to allow the
application/user to specify that 16-bit files contain sRGB data
rather than the default linear.
Fixed bugs in the pngpixel and makepng test programs.
Version 1.6.1beta08 [March 7, 2013]
Fixed CMakelists.txt to allow building a single variant of the library
(Claudio Bley):
Introduced a PNG_LIB_TARGETS variable that lists all activated library
targets. It is an error if this variable ends up empty, ie. you have
to build at least one library variant.
Made the *_COPY targets only depend on library targets actually being build.
Use PNG_LIB_TARGETS to unify a code path.
Changed the CREATE_SYMLINK macro to expect the full path to a file as the
first argument. When symlinking the filename component of that path is
determined and used as the link target.
Use copy_if_different in the CREATE_SYMLINK macro.
Version 1.6.1beta09 [March 13, 2013]
Eliminated two warnings from the Intel C compiler. The warnings are
technically valid, although a reasonable treatment of division would
show it to be incorrect.
Version 1.6.1rc01 [March 21, 2013]
No changes.
Version 1.6.1 [March 28, 2013]
No changes.
Version 1.6.2beta01 [April 14, 2013]
Updated documentation of 1.5.x to 1.6.x changes in iCCP chunk handling.
Fixed incorrect warning of excess deflate data. End condition - the
warning would be produced if the end of the deflate stream wasn't read
in the last row. The warning is harmless.
Corrected the test on user transform changes on read. It was in the
png_set of the transform function, but that doesn't matter unless the
transform function changes the rowbuf size, and that is only valid if
transform_info is called.
Corrected a misplaced closing bracket in contrib/libtests/pngvalid.c
(Flavio Medeiros).
Corrected length written to uncompressed iTXt chunks (Samuli Suominen).
Bug was introduced in libpng-1.6.0.
Version 1.6.2rc01 [April 18, 2013]
Added contrib/tools/fixitxt.c, to repair the erroneous iTXt chunk length
written by libpng-1.6.0 and 1.6.1.
Disallow storing sRGB information when the sRGB is not supported.
Version 1.6.2rc02 [April 18, 2013]
Merge pngtest.c with libpng-1.7.0
Version 1.6.2rc03 [April 22, 2013]
Trivial spelling cleanup.
Version 1.6.2rc04 and 1.6.2rc05 [omitted]
Version 1.6.2rc06 [April 24, 2013]
Reverted to version 1.6.2rc03. Recent changes to arm/neon support
have been ported to libpng-1.7.0beta09 and will reappear in version
1.6.3beta01.
Version 1.6.2 [April 25, 2013]
No changes.
Version 1.6.3beta01 [April 25, 2013]
Revised stack marking in arm/filter_neon.S and configure.ac.
Ensure that NEON filter stuff is completely disabled when switched 'off'.
Previously the ARM NEON specific files were still built if the option
was switched 'off' as opposed to being explicitly disabled.
Version 1.6.3beta02 [April 26, 2013]
Test for 'arm*' not just 'arm' in the host_cpu configure variable.
Rebuilt the configure scripts.
Version 1.6.3beta03 [April 30, 2013]
Expanded manual paragraph about writing private chunks, particularly
the need to call png_set_keep_unknown_chunks() when writing them.
Avoid dereferencing NULL pointer possibly returned from
png_create_write_struct() (Andrew Church).
Version 1.6.3beta05 [May 9, 2013]
Calculate our own zlib windowBits when decoding rather than trusting the
CMF bytes in the PNG datastream.
Added an option to force maximum window size for inflating, which was
the behavior of libpng15 and earlier, via a new PNG_MAXIMUM_INFLATE_WINDOW
option for png_set_options().
Added png-fix-itxt and png-fix-too-far-back to the built programs and
removed warnings from the source code and timepng that are revealed as
a result.
Detect wrong libpng versions linked to png-fix-too-far-back, which currently
only works with libpng versions that can be made to reliably fail when
the deflate data contains an out-of-window reference. This means only
1.6 and later.
Fixed gnu issues: g++ needs a static_cast, gcc 4.4.7 has a broken warning
message which it is easier to work round than ignore.
Updated contrib/pngminus/pnm2png.c (Paul Stewart):
Check for EOF
Ignore "#" delimited comments in input file to pnm2png.c.
Fixed whitespace handling
Added a call to png_set_packing()
Initialize dimension values so if sscanf fails at least we have known
invalid values.
Attempt to detect configuration issues with png-fix-too-far-back, which
requires both the correct libpng and the correct zlib to function
correctly.
Check ZLIB_VERNUM for mismatches, enclose #error in quotes
Added information in the documentation about problems with and fixes for
the bad CRC and bad iTXt chunk situations.
Version 1.6.3beta06 [May 12, 2013]
Allow contrib/pngminus/pnm2png.c to compile without WRITE_INVERT and
WRITE_PACK supported (writes error message that it can't read P1 or
P4 PBM files).
Improved png-fix-too-far-back usage message, added --suffix option.
Revised contrib/pngminim/*/makefile to generate pnglibconf.h with the
right zlib header files.
Separated CPPFLAGS and CFLAGS in contrib/pngminim/*/makefile
Version 1.6.3beta07 [June 8, 2013]
Removed a redundant test in png_set_IHDR().
Added set(CMAKE_CONFIGURATION_TYPES ...) to CMakeLists.txt (Andrew Hundt)
Deleted set(CMAKE_BUILD_TYPE) block from CMakeLists.txt
Enclose the prototypes for the simplified write API in
#ifdef PNG_STDIO_SUPPORTED/#endif
Make ARM NEON support work at compile time (not just configure time).
This moves the test on __ARM_NEON__ into pngconf.h to avoid issues when
using a compiler that compiles for multiple architectures at one time.
Removed PNG_FILTER_OPTIMIZATIONS and PNG_ARM_NEON_SUPPORTED from
pnglibconf.h, allowing more of the decisions to be made internally
(pngpriv.h) during the compile. Without this, symbol prefixing is broken
under certain circumstances on ARM platforms. Now only the API parts of
the optimizations ('check' vs 'api') are exposed in the public header files
except that the new setting PNG_ARM_NEON_OPT documents how libpng makes the
decision about whether or not to use the optimizations.
Protect symbol prefixing against CC/CPPFLAGS/CFLAGS usage.
Previous iOS/Xcode fixes for the ARM NEON optimizations moved the test
on __ARM_NEON__ from configure time to compile time. This breaks symbol
prefixing because the definition of the special png_init_filter_functions
call was hidden at configure time if the relevant compiler arguments are
passed in CFLAGS as opposed to CC. This change attempts to avoid all
the confusion that would result by declaring the init function even when
it is not used, so that it will always get prefixed.
Version 1.6.3beta08 [June 18, 2013]
Revised libpng.3 so that "doclifter" can process it.
Version 1.6.3beta09 [June 27, 2013]
Revised example.c to illustrate use of PNG_DEFAULT_sRGB and PNG_GAMMA_MAC_18
as parameters for png_set_gamma(). These have been available since
libpng-1.5.4.
Renamed contrib/tools/png-fix-too-far-back.c to pngfix.c and revised it
to check all compressed chunks known to libpng.
Version 1.6.3beta10 [July 5, 2013]
Updated documentation to show default behavior of benign errors correctly.
Only compile ARM code when PNG_READ_SUPPORTED is defined.
Fixed undefined behavior in contrib/tools/pngfix.c and added new strip
option. pngfix relied on undefined behavior and even a simple change from
gcc to g++ caused it to fail. The new strip option 'unsafe' has been
implemented and is the default if --max is given. Option names have
been clarified, with --strip=transform now stripping the bKGD chunk,
which was stripped previously with --strip=unused.
Added all documented chunk types to pngpriv.h
Unified pngfix.c source with libpng17.
Version 1.6.3rc01 [July 11, 2013]
No changes.
Version 1.6.3 [July 18, 2013]
Revised manual about changes in iTXt chunk handling made in libpng-1.6.0.
Added "/* SAFE */" comments in pngrutil.c and pngrtran.c where warnings
may be erroneously issued by code-checking applications.
Version 1.6.4beta01 [August 21, 2013]
Added information about png_set_options() to the manual.
Delay calling png_init_filter_functions() until a row with nonzero filter
is found.
Version 1.6.4beta02 [August 30, 2013]
Fixed inconsistent conditional compilation of png_chunk_unknown_handling()
prototype, definition, and usage. Made it depend on
PNG_HANDLE_AS_UNKNOWN_SUPPORTED everywhere.
Version 1.6.4rc01 [September 5, 2013]
No changes.
Version 1.6.4 [September 12, 2013]
No changes.
Version 1.6.5 [September 14, 2013]
Removed two stray lines of code from arm/arm_init.c.
Version 1.6.6 [September 16, 2013]
Removed two stray lines of code from arm/arm_init.c, again.
Version 1.6.7beta01 [September 30, 2013]
Revised unknown chunk code to correct several bugs in the NO_SAVE_/NO_WRITE
combination
Allow HANDLE_AS_UNKNOWN to work when other options are configured off. Also
fixed the pngminim makefiles to work when $(MAKEFLAGS) contains stuff
which terminates the make options (as by default in recent versions of
Gentoo).
Avoid up-cast warnings in pngvalid.c. On ARM the alignment requirements of
png_modifier are greater than that of png_store and as a consequence
compilation of pngvalid.c results in a warning about increased alignment
requirements because of the bare cast to (png_modifier*). The code is safe,
because the pointer is known to point to a stack allocated png_modifier,
but this change avoids the warning.
Fixed default behavior of ARM_NEON_API. If the ARM NEON API option was
compiled without the CHECK option it defaulted to on, not off.
Check user callback behavior in pngunknown.c. Previous versions compiled
if SAVE_UNKNOWN was not available but did nothing since the callback
was never implemented.
Merged pngunknown.c with 1.7 version and back ported 1.7 improvements/fixes
Version 1.6.7beta02 [October 12, 2013]
Made changes for compatibility with automake 1.14:
1) Added the 'compile' program to the list of programs that must be cleaned
in autogen.sh
2) Added 'subdir-objects' which causes .c files in sub-directories to be
compiled such that the corresponding .o files are also in the
sub-directory. This is because automake 1.14 warns that the
current behavior of compiling to the top level directory may be removed
in the future.
3) Updated dependencies on pnglibconf.h to match the new .o locations and
added all the files in contrib/libtests and contrib/tools that depend
on pnglibconf.h
4) Added 'BUILD_SOURCES = pnglibconf.h'; this is the automake recommended
way of handling the dependencies of sources that are machine generated;
unfortunately it only works if the user does 'make all' or 'make check',
so the dependencies (3) are still required.
Cleaned up (char*) casts of zlib messages. The latest version of the Intel C
compiler complains about casting a string literal as (char*), so copied the
treatment of z_const from the library code into pngfix.c
Simplified error message code in pngunknown. The simplification has the
useful side effect of avoiding a bogus warning generated by the latest
version of the Intel C compiler (it objects to
condition ? string-literal : string-literal).
Make autogen.sh work with automake 1.13 as well as 1.14. Do this by always
removing the 1.14 'compile' script but never checking for it.
Version 1.6.7beta03 [October 19, 2013]
Added ARMv8 support (James Yu ). Added file
arm/filter_neon_intrinsics.c; enable with -mfpu=neon.
Revised pngvalid to generate size images with as many filters as it can
manage, limited by the number of rows.
Cleaned up ARM NEON compilation handling. The tests are now in pngpriv.h
and detect the broken GCC compilers.
Version 1.6.7beta04 [October 26, 2013]
Allow clang derived from older GCC versions to use ARM intrinsics. This
causes all clang builds that use -mfpu=neon to use the intrinsics code,
not the assembler code. This has only been tested on iOS 7. It may be
necessary to exclude some earlier clang versions but this seems unlikely.
Changed NEON implementation selection mechanism. This allows assembler
or intrinsics to be turned on at compile time during the build by defining
PNG_ARM_NEON_IMPLEMENTATION to the correct value (2 or 1). This macro
is undefined by default and the build type is selected in pngpriv.h.
Version 1.6.7rc01 [November 2, 2013]
No changes.
Version 1.6.7rc02 [November 7, 2013]
Fixed #include in filter_neon_intrinsics.c and ctype macros. The ctype char
checking macros take an unsigned char argument, not a signed char.
Version 1.6.7 [November 14, 2013]
No changes.
Version 1.6.8beta01 [November 24, 2013]
Moved prototype for png_handle_unknown() in pngpriv.h outside of
the #ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED/#endif block.
Added "-Wall" to CFLAGS in contrib/pngminim/*/makefile
Conditionally compile some unused functions reported by -Wall in
pngminim.
Fixed 'minimal' builds. Various obviously useful minimal configurations
don't build because of missing contrib/libtests test programs and
overly complex dependencies in scripts/pnglibconf.dfa. This change
adds contrib/conftest/*.dfa files that can be used in automatic build
scripts to ensure that these configurations continue to build.
Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder.
Fixed pngvalid 'fail' function declaration on the Intel C Compiler.
This reverts to the previous 'static' implementation and works round
the 'unused static function' warning by using PNG_UNUSED().
Version 1.6.8beta02 [November 30, 2013]
Removed or marked PNG_UNUSED some harmless "dead assignments" reported
by clang scan-build.
Changed tabs to 3 spaces in png_debug macros and changed '"%s"m'
to '"%s" m' to improve portability among compilers.
Changed png_free_default() to free() in pngtest.c
Version 1.6.8rc01 [December 12, 2013]
Tidied up pngfix inits and fixed pngtest no-write builds.
Version 1.6.8rc02 [December 14, 2013]
Handle zero-length PLTE chunk or NULL palette with png_error()
instead of png_chunk_report(), which by default issues a warning
rather than an error, leading to later reading from a NULL pointer
(png_ptr->palette) in png_do_expand_palette(). This is CVE-2013-6954
and VU#650142. Libpng-1.6.1 through 1.6.7 are vulnerable.
Libpng-1.6.0 and earlier do not have this bug.
Version 1.6.8 [December 19, 2013]
No changes.
Version 1.6.9beta01 [December 26, 2013]
Bookkeeping: Moved functions around (no changes). Moved transform
function definitions before the place where they are called so that
they can be made static. Move the intrapixel functions and the
grayscale palette builder out of the png?tran.c files. The latter
isn't a transform function and is no longer used internally, and the
former MNG specific functions are better placed in pngread/pngwrite.c
Made transform implementation functions static. This makes the internal
functions called by png_do_{read|write}_transformations static. On an
x86-64 DLL build (Gentoo Linux) this reduces the size of the text
segment of the DLL by 1208 bytes, about 0.6%. It also simplifies
maintenance by removing the declarations from pngpriv.h and allowing
easier changes to the internal interfaces.
Rebuilt configure scripts with automake-1.14.1 and autoconf-2.69
in the tar distributions.
Version 1.6.9beta02 [January 1, 2014]
Added checks for libpng 1.5 to pngvalid.c. This supports the use of
this version of pngvalid in libpng 1.5
Merged with pngvalid.c from libpng-1.7 changes to create a single
pngvalid.c
Removed #error macro from contrib/tools/pngfix.c (Thomas Klausner).
Merged pngrio.c, pngtrans.c, pngwio.c, and pngerror.c with libpng-1.7.0
Merged libpng-1.7.0 changes to make no-interlace configurations work
with test programs.
Revised pngvalid.c to support libpng 1.5, which does not support the
PNG_MAXIMUM_INFLATE_WINDOW option, so #define it out when appropriate in
pngvalid.c
Allow unversioned links created on install to be disabled in configure.
In configure builds 'make install' changes/adds links like png.h
and libpng.a to point to the newly installed, versioned, files (e.g.
libpng17/png.h and libpng17.a). Three new configure options and some
rearrangement of Makefile.am allow creation of these links to be disabled.
Version 1.6.9beta03 [January 10, 2014]
Removed potentially misleading warning from png_check_IHDR().
Version 1.6.9beta04 [January 20, 2014]
Updated scripts/makefile.* to use CPPFLAGS (Cosmin).
Added clang attribute support (Cosmin).
Version 1.6.9rc01 [January 28, 2014]
No changes.
Version 1.6.9rc02 [January 30, 2014]
Quiet an uninitialized memory warning from VC2013 in png_get_png().
Version 1.6.9 [February 6, 2014]
Version 1.6.10beta01 [February 9, 2014]
Backported changes from libpng-1.7.0beta30 and beta31:
Fixed a large number of instances where PNGCBAPI was omitted from
function definitions.
Added pngimage test program for png_read_png() and png_write_png()
with two new test scripts.
Removed dependence on !PNG_READ_EXPAND_SUPPORTED for calling
png_set_packing() in png_read_png().
Fixed combination of ~alpha with shift. On read invert alpha, processing
occurred after shift processing, which causes the final values to be
outside the range that should be produced by the shift. Reversing the
order on read makes the two transforms work together correctly and mirrors
the order used on write.
Do not read invalid sBIT chunks. Previously libpng only checked sBIT
values on write, so a malicious PNG writer could therefore cause
the read code to return an invalid sBIT chunk, which might lead to
application errors or crashes. Such chunks are now skipped (with
chunk_benign_error).
Make png_read_png() and png_write_png() prototypes in png.h depend
upon PNG_READ_SUPPORTED and PNG_WRITE_SUPPORTED.
Support builds with unsupported PNG_TRANSFORM_* values. All of the
PNG_TRANSFORM_* values are always defined in png.h and, because they
are used for both read and write in some cases, it is not reliable
to #if out ones that are totally unsupported. This change adds error
detection in png_read_image() and png_write_image() to do a
png_app_error() if the app requests something that cannot be done
and it adds corresponding code to pngimage.c to handle such options
by not attempting to test them.
Version 1.6.10beta02 [February 23, 2014]
Moved redefines of png_error(), png_warning(), png_chunk_error(),
and png_chunk_warning() from pngpriv.h to png.h to make them visible
to libpng-calling applications.
Moved OS dependent code from arm/arm_init.c, to allow the included
implementation of the ARM NEON discovery function to be set at
build-time and provide sample implementations from the current code in the
contrib/arm-neon subdirectory. The __linux__ code has also been changed to
compile and link on Android by using /proc/cpuinfo, and the old linux code
is in contrib/arm-neon/linux-auxv.c. The new code avoids POSIX and Linux
dependencies apart from opening /proc/cpuinfo and is C90 compliant.
Check for info_ptr == NULL early in png_read_end() so we don't need to
run all the png_handle_*() and depend on them to return if info_ptr == NULL.
This improves the performance of png_read_end(png_ptr, NULL) and makes
it more robust against future programming errors.
Check for __has_extension before using it in pngconf.h, to
support older Clang versions (Jeremy Sequoia).
Treat CRC error handling with png_set_crc_action(), instead of with
png_set_benign_errors(), which has been the case since libpng-1.6.0beta18.
Use a user warning handler in contrib/gregbook/readpng2.c instead of default,
so warnings will be put on stderr even if libpng has CONSOLE_IO disabled.
Added png_ptr->process_mode = PNG_READ_IDAT_MODE in png_push_read_chunk
after recognizing the IDAT chunk, which avoids an infinite loop while
reading a datastream whose first IDAT chunk is of zero-length.
This fixes CERT VU#684412 and CVE-2014-0333.
Don't recognize known sRGB profiles as sRGB if they have been hacked,
but don't reject them and don't issue a copyright violation warning.
Version 1.6.10beta03 [February 25, 2014]
Moved some documentation from png.h to libpng.3 and libpng-manual.txt
Minor editing of contrib/arm-neon/README and contrib/examples/*.c
Version 1.6.10rc01 [February 27, 2014]
Fixed typos in the manual and in scripts/pnglibconf.dfa (CFLAGS -> CPPFLAGS
and PNG_USR_CONFIG -> PNG_USER_CONFIG).
Version 1.6.10rc02 [February 28, 2014]
Removed unreachable return statement after png_chunk_error()
in pngrutil.c
Version 1.6.10rc03 [March 4, 2014]
Un-deprecated png_data_freer().
Version 1.6.10 [March 6, 2014]
No changes.
Version 1.6.11beta01 [March 17, 2014]
Use "if (value != 0)" instead of "if (value)" consistently.
Changed ZlibSrcDir from 1.2.5 to 1.2.8 in projects/vstudio.
Moved configuration information from the manual to the INSTALL file.
Version 1.6.11beta02 [April 6, 2014]
Removed #if/#else/#endif from inside two pow() calls in pngvalid.c because
they were handled improperly by Portland Group's PGI-14.1 - PGI-14.3
when using its "__builtin_pow()" function.
Silence 'unused parameter' build warnings (Cosmin Truta).
$(CP) is now used alongside $(RM_F). Also, use 'copy' instead of 'cp'
where applicable, and applied other minor makefile changes (Cosmin).
Don't warn about invalid dimensions exceeding user limits (Cosmin).
Allow an easy replacement of the default pre-built configuration
header with a custom header, via the make PNGLIBCONF_H_PREBUILT
macro (Cosmin).
Version 1.6.11beta03 [April 6, 2014]
Fixed a typo in pngrutil.c, introduced in libpng-1.5.6, that interferes
with "blocky" expansion of sub-8-bit interlaced PNG files (Eric Huss).
Optionally use __builtin_bswap16() in png_do_swap().
Version 1.6.11beta04 [April 19, 2014]
Made progressive reading of interlaced images consistent with the
behavior of the sequential reader and consistent with the manual, by
moving some code out of the PNG_READ_INTERLACING_SUPPORTED blocks. The
row_callback now receives the proper pass number and unexpanded rows, when
png_combine_row() isn't built or used, and png_set_interlace_handling()
is not called.
Allow PNG_sRGB_PROFILE_CHECKING = (-1) to mean no sRGB profile checking.
Version 1.6.11beta05 [April 26, 2014]
Do not reject ICC V2 profiles that lack padding (Kai-Uwe Behrmann).
Relocated closing bracket of the sRGB profile test loop to avoid getting
"Not recognizing known sRGB profile that has been edited" warning for
ICC V2 profiles that lack the MD5 signature in the profile header.
Version 1.6.11beta06 [May 19, 2014]
Added PNG_SKIP_sRGB_CHECK_PROFILE choice for png_set_option().
Version 1.6.11rc01 [May 27, 2014]
No changes.
Version 1.6.11rc02 [June 3, 2014]
Test ZLIB_VERNUM instead of PNG_ZLIB_VERNUM in contrib/tools/pngfix.c
Version 1.6.11 [June 5, 2014]
No changes.
Version 1.6.12rc01 [June 6, 2014]
Relocated new code from 1.6.11beta06 in png.c to a point after the
declarations (Max Stepin).
Version 1.6.12rc02 [June 7, 2014]
Changed file permissions of contrib/tools/intgamma.sh,
test-driver, and compile from 0644 to 0755 (Cosmin).
Version 1.6.12rc03 [June 8, 2014]
Ensure "__has_attribute()" macro exists before trying to use it with
old clang compilers (MacPorts Ticket #43939).
Version 1.6.12 [June 12, 2014]
No changes.
Version 1.6.13beta01 [July 4, 2014]
Quieted -Wsign-compare and -Wclobber compiler warnings in
contrib/pngminus/*.c
Added "(void) png_ptr;" where needed in contrib/gregbook to quiet
compiler complaints about unused pointers.
Split a long output string in contrib/gregbook/rpng2-x.c.
Added "PNG_SET_OPTION" requirement for sRGB chunk support to pnglibconf.dfa,
Needed for write-only support (John Bowler).
Changed "if defined(__ARM_NEON__)" to
"if (defined(__ARM_NEON__) || defined(__ARM_NEON))" (James Wu).
Fixed clang no-warning builds: png_digit was defined but never used.
Version 1.6.13beta02 [July 21, 2014]
Fixed an incorrect separator ("/" should be "\") in scripts/makefile.vcwin32
(bug report from Wolfgang S. Kechel). Bug was introduced in libpng-1.6.11.
Also fixed makefile.bc32, makefile.bor, makefile.msc, makefile.intel, and
makefile.tc3 similarly.
Version 1.6.13beta03 [August 3, 2014]
Removed scripts/makefile.elf. It has not worked since libpng-1.5.0beta14
due to elimination of the PNG_FUNCTION_EXPORT and PNG_DATA_EXPORT
definitions from pngconf.h.
Ensure that CMakeLists.txt makes the target "lib" directory before making
symbolic link into it (SourceForge bug report #226 by Rolf Timmermans).
Version 1.6.13beta04 [August 8, 2014]
Added opinion that the ECCN (Export Control Classification Number) for
libpng is EAR99 to the README file.
Eliminated use of "$<" in makefile explicit rules, when copying
$PNGLIBCONF_H_PREBUILT. This does not work on some versions of make;
bug introduced in libpng version 1.6.11.
Version 1.6.13rc01 [August 14, 2014]
Made "ccopts" agree with "CFLAGS" in scripts/makefile.hp* and makefile.*sunu
Version 1.6.13 [August 21, 2014]
No changes.
Version 1.6.14beta01 [September 14, 2014]
Guard usage of png_ptr->options with #ifdef PNG_SET_OPTION_SUPPORTED.
Do not build contrib/tools/pngfix.c when PNG_SETJMP_NOT_SUPPORTED,
to allow "make" to complete without setjmp support (bug report by
Claudio Fontana)
Add "#include " to contrib/tools/pngfix.c (John Bowler)
Version 1.6.14beta02 [September 18, 2014]
Use nanosleep() instead of usleep() in contrib/gregbook/rpng2-x.c
because usleep() is deprecated.
Define usleep() in contrib/gregbook/rpng2-x.c if not already defined
in unistd.h and nanosleep() is not available; fixes error introduced
in libpng-1.6.13.
Disable floating point exception handling in pngvalid.c when
PNG_FLOATING_ARITHMETIC is not supported (bug report by "zootus
at users.sourceforge.net").
Version 1.6.14beta03 [September 19, 2014]
Define FE_DIVBYZERO, FE_INVALID, and FE_OVERFLOW in pngvalid.c if not
already defined. Revert floating point exception handling in pngvalid.c
to version 1.6.14beta01 behavior.
Version 1.6.14beta04 [September 27, 2014]
Fixed incorrect handling of the iTXt compression flag in pngrutil.c
(bug report by Shunsaku Hirata). Bug was introduced in libpng-1.6.0.
Version 1.6.14beta05 [October 1, 2014]
Added "option READ_iCCP enables READ_COMPRESSED_TEXT" to pnglibconf.dfa
Version 1.6.14beta06 [October 5, 2014]
Removed unused "text_len" parameter from private function png_write_zTXt().
Conditionally compile some code in png_deflate_claim(), when
PNG_WARNINGS_SUPPORTED and PNG_ERROR_TEXT_SUPPORTED are disabled.
Replaced repeated code in pngpread.c with PNG_PUSH_SAVE_BUFFER_IF_FULL.
Added "chunk iTXt enables TEXT" and "chunk zTXt enables TEXT"
to pnglibconf.dfa.
Removed "option READ_COMPRESSED_TEXT enables READ_TEXT" from pnglibconf.dfa,
to make it possible to configure a libpng that supports iCCP but not TEXT.
Version 1.6.14beta07 [October 7, 2014]
Removed "option WRITE_COMPRESSED_TEXT enables WRITE_TEXT" from pnglibconf.dfa
Only mark text chunks as written after successfully writing them.
Version 1.6.14rc01 [October 15, 2014]
Fixed some typos in comments.
Version 1.6.14rc02 [October 17, 2014]
Changed png_convert_to_rfc_1123() to png_convert_to_rfc_1123_buffer()
in the manual, to reflect the change made in libpng-1.6.0.
Updated README file to explain that direct access to the png_struct
and info_struct members has not been permitted since libpng-1.5.0.
Version 1.6.14 [October 23, 2014]
No changes.
Version 1.6.15beta01 [October 29, 2014]
Changed "if (!x)" to "if (x == 0)" and "if (x)" to "if (x != 0)"
Simplified png_free_data().
Added missing "ptr = NULL" after some instances of png_free().
Version 1.6.15beta02 [November 1, 2014]
Changed remaining "if (!x)" to "if (x == 0)" and "if (x)" to "if (x != 0)"
Version 1.6.15beta03 [November 3, 2014]
Added PNG_USE_ARM_NEON configuration flag (Marcin Juszkiewicz).
Version 1.6.15beta04 [November 4, 2014]
Removed new PNG_USE_ARM_NEON configuration flag and made a one-line
revision to configure.ac to support ARM on aarch64 instead (John Bowler).
Version 1.6.15beta05 [November 5, 2014]
Use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING in
example.c, pngtest.c, and applications in the contrib directory.
Fixed an out-of-range read in png_user_version_check() (Bug report from
Qixue Xiao, CVE-2015-8540).
Simplified and future-proofed png_user_version_check().
Fixed GCC unsigned int->float warnings. Various versions of GCC
seem to generate warnings when an unsigned value is implicitly
converted to double. This is probably a GCC bug but this change
avoids the issue by explicitly converting to (int) where safe.
Free all allocated memory in pngimage. The file buffer cache was left
allocated at the end of the program, harmless but it causes memory
leak reports from clang.
Fixed array size calculations to avoid warnings. At various points
in the code the number of elements in an array is calculated using
sizeof. This generates a compile time constant of type (size_t) which
is then typically assigned to an (unsigned int) or (int). Some versions
of GCC on 64-bit systems warn about the apparent narrowing, even though
the same compiler does apparently generate the correct, in-range,
numeric constant. This adds appropriate, safe, casts to make the
warnings go away.
Version 1.6.15beta06 [November 6, 2014]
Reverted use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING
in the manual, example.c, pngtest.c, and applications in the contrib
directory. It was incorrect advice.
Version 1.6.15beta07 [November 7, 2014]
Removed #ifdef PNG_16BIT_SUPPORTED/#endif around png_product2(); it is
needed by png_reciprocal2().
Added #ifdef PNG_16BIT_SUPPORTED/#endif around png_log16bit() and
png_do_swap().
Changed all "#endif /* PNG_FEATURE_SUPPORTED */" to "#endif /* FEATURE */"
Version 1.6.15beta08 [November 8, 2014]
More housecleaning in *.h
Version 1.6.15rc01 [November 13, 2014]
Version 1.6.15rc02 [November 14, 2014]
The macros passed in the command line to Borland make were ignored if
similarly-named macros were already defined in makefiles. This behavior
is different from POSIX make and other make programs. Surround the
macro definitions with ifndef guards (Cosmin).
Version 1.6.15rc03 [November 16, 2014]
Added "-D_CRT_SECURE_NO_WARNINGS" to CFLAGS in scripts/makefile.vcwin32.
Removed the obsolete $ARCH variable from scripts/makefile.darwin.
Version 1.6.15 [November 20, 2014]
No changes.
Version 1.6.16beta01 [December 14, 2014]
Added ".align 2" to arm/filter_neon.S to support old GAS assemblers that
don't do alignment correctly.
Revised Makefile.am and scripts/symbols.dfn to work with MinGW/MSYS
(Bob Friesenhahn).
Version 1.6.16beta02 [December 15, 2014]
Revised Makefile.am and scripts/*.dfn again to work with MinGW/MSYS;
renamed scripts/*.dfn to scripts/*.c (John Bowler).
Version 1.6.16beta03 [December 21, 2014]
Quiet a "comparison always true" warning in pngstest.c (John Bowler).
Version 1.6.16rc01 [December 21, 2014]
Restored a test on width that was removed from png.c at libpng-1.6.9
(Bug report by Alex Eubanks, CVE-2015-0973).
Version 1.6.16rc02 [December 21, 2014]
Undid the update to pngrutil.c in 1.6.16rc01.
Version 1.6.16rc03 [December 21, 2014]
Fixed an overflow in png_combine_row() with very wide interlaced images
(Bug report and fix by John Bowler, CVE-2014-9495).
Version 1.6.16 [December 22, 2014]
No changes.
Version 1.6.17beta01 [January 29, 2015]
Removed duplicate PNG_SAFE_LIMITS_SUPPORTED handling from pngconf.h
Corrected the width limit calculation in png_check_IHDR().
Removed user limits from pngfix. Also pass NULL pointers to
png_read_row to skip the unnecessary row de-interlace stuff.
Added testing of png_set_packing() to pngvalid.c
Regenerated configure scripts in the *.tar distributions with libtool-2.4.4
Implement previously untested cases of libpng transforms in pngvalid.c
Fixed byte order in png_do_read_filler() with 16-bit input. Previously
the high and low bytes of the filler, from png_set_filler() or from
png_set_add_alpha(), were read in the wrong order.
Made the check for out-of-range values in png_set_tRNS() detect
values that are exactly 2^bit_depth, and work on 16-bit platforms.
Merged some parts of libpng-1.6.17beta01 and libpng-1.7.0beta47.
Added #ifndef __COVERITY__ where needed in png.c, pngrutil.c and
pngset.c to avoid warnings about dead code.
Added "& 0xff" to many instances of expressions that are typecast
to (png_byte), to avoid Coverity warnings.
Version 1.6.17beta02 [February 7, 2015]
Work around one more Coverity-scan dead-code warning.
Do not build png_product2() when it is unused.
Version 1.6.17beta03 [February 17, 2015]
Display user limits in the output from pngtest.
Eliminated the PNG_SAFE_LIMITS macro and restored the 1-million-column
and 1-million-row default limits in pnglibconf.dfa, that can be reset
by the user at build time or run time. This provides a more robust
defense against DOS and as-yet undiscovered overflows.
Version 1.6.17beta04 [February 21, 2015]
Added PNG_WRITE_CUSTOMIZE_COMPRESSION_SUPPORTED macro, on by default.
Allow user to call png_get_IHDR() with NULL arguments (Reuben Hawkins).
Rebuilt configure scripts with automake-1.15 and libtool-2.4.6
Version 1.6.17beta05 [February 25, 2015]
Restored compiling of png_reciprocal2 with PNG_NO_16BIT.
Version 1.6.17beta06 [February 27, 2015]
Moved png_set_filter() prototype into a PNG_WRITE_SUPPORTED block
of png.h.
Avoid runtime checks when converting integer to png_byte with
Visual Studio (Sergey Kosarevsky)
Version 1.6.17rc01 [March 4, 2015]
No changes.
Version 1.6.17rc02 [March 9, 2015]
Removed some comments that the configure script did not handle
properly from scripts/pnglibconf.dfa and pnglibconf.h.prebuilt.
Free the unknown_chunks structure even when it contains no data.
Version 1.6.17rc03 [March 12, 2015]
Updated CMakeLists.txt to add OSX framework, change YES/NO to ON/OFF
for consistency, and remove some useless tests (Alexey Petruchik).
Version 1.6.17rc04 [March 16, 2015]
Remove pnglibconf.h, pnglibconf.c, and pnglibconf.out instead of
pnglibconf.* in "make clean" (Cosmin).
Fix bug in calculation of maxbits, in png_write_sBIT, introduced
in libpng-1.6.17beta01 (John Bowler).
Version 1.6.17rc05 [March 21, 2015]
Define PNG_FILTER_* and PNG_FILTER_VALUE_* in png.h even when WRITE
is not supported (John Bowler). This fixes an error introduced in
libpng-1.6.17beta06.
Reverted "& 0xff" additions of version 1.6.17beta01. Libpng passes
the Coverity scan without them.
Version 1.6.17rc06 [March 23, 2015]
Remove pnglibconf.dfn and pnglibconf.pre with "make clean".
Reformatted some "&0xff" instances to "& 0xff".
Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha
value was wrong. It's not clear if this affected the final stored
value; in the obvious code path the upper and lower 8-bits of the
alpha value were identical and the alpha was truncated to 8-bits
rather than dividing by 257 (John Bowler).
Version 1.6.17 [March 26, 2015]
No changes.
Version 1.6.18beta01 [April 1, 2015]
Removed PNG_SET_CHUNK_[CACHE|MALLOC]_LIMIT_SUPPORTED macros. They
have been combined with PNG_SET_USER_LIMITS_SUPPORTED (resolves
bug report by Andrew Church).
Fixed rgb_to_gray checks and added tRNS checks to pngvalid.c. This
fixes some arithmetic errors that caused some tests to fail on
some 32-bit platforms (Bug reports by Peter Breitenlohner [i686]
and Petr Gajdos [i586]).
Version 1.6.18beta02 [April 26, 2015]
Suppressed some warnings from the Borland C++ 5.5.1/5.82 compiler
(Bug report by Viktor Szakats).
Version 1.6.18beta03 [May 6, 2015]
Replaced "unexpected" with an integer (0xabadca11) in pngset.c
where a long was expected, to avoid a compiler warning when PNG_DEBUG > 1.
Added contrib/examples/simpleover.c, to demonstrate how to handle
alpha compositing of multiple images, using the "simplified API"
and an example PNG generation tool, contrib/examples/genpng.c
(John Bowler).
Version 1.6.18beta04 [May 20, 2015]
PNG_RELEASE_BUILD replaces tests where the code depended on the build base
type and can be defined on the command line, allowing testing in beta
builds (John Bowler).
Avoid Coverity issue 80858 (REVERSE NULL) in pngtest.c PNG_DEBUG builds.
Avoid a harmless potential integer overflow in png_XYZ_from_xy() (Bug
report from Christopher Ferris).
Version 1.6.18beta05 [May 31, 2015]
Backport filter selection code from libpng-1.7.0beta51, to combine
sub_row, up_row, avg_row, and paeth_row into try_row and tst_row.
Changed png_voidcast(), etc., to voidcast(), etc., in contrib/tools/pngfix.c
to avoid confusion with the libpng private macros.
Fixed old cut&paste bug in the weighted filter selection code in
pngwutil.c, introduced in libpng-0.95, March 1997.
Version 1.6.18beta06 [June 1, 2015]
Removed WRITE_WEIGHTED_FILTERED code, to save a few kbytes of the
compiled library size. It never worked properly and as far as we can
tell, no one uses it. The png_set_filter_heuristics() and
png_set_filter_heuristics_fixed() APIs are retained but deprecated
and do nothing.
Version 1.6.18beta07 [June 6, 2015]
Removed non-working progressive reader 'skip' function. This
function has apparently never been used. It was implemented
to support back-door modification of png_struct in libpng-1.4.x
but (because it does nothing and cannot do anything) was apparently
never tested (John Bowler).
Fixed cexcept.h in which GCC 5 now reports that one of the auto
variables in the Try macro needs to be volatile to prevent value
being lost over the setjmp (John Bowler).
Fixed NO_WRITE_FILTER and -Wconversion build breaks (John Bowler).
Fix g++ build breaks (John Bowler).
Quieted some Coverity issues in pngfix.c, png-fix-itxt.c, pngvalid.c,
pngstest.c, and pngimage.c. Most seem harmless, but png-fix-itxt
would only work with iTXt chunks with length 255 or less.
Added #ifdef's to contrib/examples programs so people don't try
to compile them without the minimum required support enabled
(suggested by Flavio Medeiros).
Version 1.6.18beta08 [June 30, 2015]
Eliminated the final two Coverity defects (insecure temporary file
handling in contrib/libtests/pngstest.c; possible overflow of
unsigned char in contrib/tools/png-fix-itxt.c). To use the "secure"
file handling, define PNG_USE_MKSTEMP, otherwise "tmpfile()" will
be used.
Removed some unused WEIGHTED_FILTER macros from png.h and pngstruct.h
Version 1.6.18beta09 [July 5, 2015]
Removed some useless typecasts from contrib/tools/png-fix-itxt.c
Fixed a new signed-unsigned comparison in pngrtran.c (Max Stepin).
Replaced arbitrary use of 'extern' with #define PNG_LINKAGE_*. To
preserve API compatibility, the new defines all default to "extern"
(requested by Jan Nijtmans).
Version 1.6.18rc01 [July 9, 2015]
Belatedly added Mans Rullgard and James Yu to the list of Contributing
Authors.
Version 1.6.18rc02 [July 12, 2015]
Restored unused FILTER_HEURISTIC macros removed at libpng-1.6.18beta08
to png.h to avoid compatibility warnings.
Version 1.6.18rc03 [July 15, 2015]
Minor changes to the man page
Version 1.6.18 [July 23, 2015]
No changes.
Version 1.6.19beta01 [July 30, 2015]
Updated obsolete information about the simplified API macros in the
manual pages (Bug report by Arc Riley).
Avoid potentially dereferencing NULL info_ptr in png_info_init_3().
Rearranged png.h to put the major sections in the same order as
in libpng17.
Eliminated unused PNG_COST_SHIFT, PNG_WEIGHT_SHIFT, PNG_COST_FACTOR, and
PNG_WEIGHT_FACTOR macros.
Suppressed some warnings from the Borland C++ 5.5.1/5.82 compiler
(Bug report by Viktor Szakats). Several warnings remain and are
unavoidable, where we test for overflow.
Fixed potential leak of png_pixels in contrib/pngminus/pnm2png.c
Fixed uninitialized variable in contrib/gregbook/rpng2-x.c
Version 1.6.19beta02 [August 19, 2015]
Moved config.h.in~ from the "libpng_autotools_files" list to the
"libpng_autotools_extra" list in autogen.sh because it was causing a
false positive for missing files (bug report by Robert C. Seacord).
Removed unreachable "break" statements in png.c, pngread.c, and pngrtran.c
to suppress clang warnings (Bug report by Viktor Szakats).
Fixed some bad links in the man page.
Changed "n bit" to "n-bit" in comments.
Added signed/unsigned 16-bit safety net. This removes the dubious
0x8000 flag definitions on 16-bit systems. They aren't supported
yet the defs *probably* work, however it seems much safer to do this
and be advised if anyone, contrary to advice, is building libpng 1.6
on a 16-bit system. It also adds back various switch default clauses
for GCC; GCC errors out if they are not present (with an appropriately
high level of warnings).
Safely convert num_bytes to a png_byte in png_set_sig_bytes() (Robert
Seacord).
Fixed the recently reported 1's complement security issue by replacing
the value that is illegal in the PNG spec, in both signed and unsigned
values, with 0. Illegal unsigned values (anything greater than or equal
to 0x80000000) can still pass through, but since these are not illegal
in ANSI-C (unlike 0x80000000 in the signed case) the checking that
occurs later can catch them (John Bowler).
Version 1.6.19beta03 [September 26, 2015]
Fixed png_save_int_32 when int is not 2's complement (John Bowler).
Updated libpng16 with all the recent test changes from libpng17,
including changes to pngvalid.c to ensure that the original,
distributed, version of contrib/visupng/cexcept.h can be used
(John Bowler).
pngvalid contains the correction to the use of SAVE/STORE_
UNKNOWN_CHUNKS; a bug revealed by changes in libpng 1.7. More
tests contain the --strict option to detect warnings and the
pngvalid-standard test has been corrected so that it does not
turn on progressive-read. There is a separate test which does
that. (John Bowler)
Also made some signed/unsigned fixes.
Make pngstest error limits version specific. Splitting the machine
generated error structs out to a file allows the values to be updated
without changing pngstest.c itself. Since libpng 1.6 and 1.7 have
slightly different error limits this simplifies maintenance. The
makepngs.sh script has also been updated to more accurately reflect
current problems in libpng 1.7 (John Bowler).
Incorporated new test PNG files into make check. tests/pngstest-*
are changed so that the new test files are divided into 8 groups by
gamma and alpha channel. These tests have considerably better code
and pixel-value coverage than contrib/pngsuite; however,coverage is
still incomplete (John Bowler).
Removed the '--strict' in 1.6 because of the double-gamma-correction
warning, updated pngstest-errors.h for the errors detected with the
new contrib/testspngs PNG test files (John Bowler).
Version 1.6.19beta04 [October 15, 2015]
Worked around rgb-to-gray issues in libpng 1.6. The previous
attempts to ignore the errors in the code aren't quite enough to
deal with the 'channel selection' encoding added to libpng 1.7; abort.
pngvalid.c is changed to drop this encoding in prior versions.
Fixed 'pow' macros in pngvalid.c. It is legal for 'pow' to be a
macro, therefore the argument list cannot contain preprocessing
directives. Make sure pow is a function where this happens. This is
a minimal safe fix, the issue only arises in non-performance-critical
code (bug report by Curtis Leach, fix by John Bowler).
Added sPLT support to pngtest.c
Version 1.6.19rc01 [October 23, 2015]
No changes.
Version 1.6.19rc02 [October 31, 2015]
Prevent setting or writing over-length PLTE chunk (Cosmin Truta).
Silently truncate over-length PLTE chunk while reading.
Libpng incorrectly calculated the output rowbytes when the application
decreased either the number of channels or the bit depth (or both) in
a user transform. This was safe; libpng overallocated buffer space
(potentially by quite a lot; up to 4 times the amount required) but,
from 1.5.4 on, resulted in a png_error (John Bowler).
Version 1.6.19rc03 [November 3, 2015]
Fixed some inconsequential cut-and-paste typos in png_set_cHRM_XYZ_fixed().
Clarified COPYRIGHT information to state explicitly that versions
are derived from previous versions.
Removed much of the long list of previous versions from png.h and
libpng.3.
Version 1.6.19rc04 [November 5, 2015]
Fixed new bug with CRC error after reading an over-length palette
(bug report by Cosmin Truta) (CVE-2015-8126).
Version 1.6.19 [November 12, 2015]
Cleaned up coding style in png_handle_PLTE().
Version 1.6.20beta01 [November 20, 2015]
Avoid potential pointer overflow/underflow in png_handle_sPLT() and
png_handle_pCAL() (Bug report by John Regehr).
Version 1.6.20beta02 [November 23, 2015]
Fixed incorrect implementation of png_set_PLTE() that uses png_ptr
not info_ptr, that left png_set_PLTE() open to the CVE-2015-8126
vulnerability. Fixes CVE-2015-8472.
Version 1.6.20beta03 [November 24, 2015]
Backported tests from libpng-1.7.0beta69.
Version 1.6.20rc01 [November 26, 2015]
Fixed an error in handling of bad zlib CMINFO field in pngfix, found by
American Fuzzy Lop, reported by Brian Carpenter. inflate() doesn't
immediately fault a bad CMINFO field; instead a 'too far back' error
happens later (at least some times). pngfix failed to limit CMINFO to
the allowed values but then assumed that window_bits was in range,
triggering an assert. The bug is mostly harmless; the PNG file cannot
be fixed.
Version 1.6.20rc02 [November 29, 2015]
In libpng 1.6 zlib initialization was changed to use the window size
in the zlib stream, not a fixed value. This causes some invalid images,
where CINFO is too large, to display 'correctly' if the rest of the
data is valid. This provides a workaround for zlib versions where the
error arises (ones that support the API change to use the window size
in the stream).
Version 1.6.20 [December 3, 2015]
No changes.
Version 1.6.21beta01 [December 11, 2015]
Fixed syntax "$(command)" in tests/pngstest that some shells other than
bash could not parse (Bug report by Nelson Beebe). Use `command` instead.
Version 1.6.21beta02 [December 14, 2015]
Moved png_check_keyword() from pngwutil.c to pngset.c
Removed LE/BE dependencies in pngvalid, to 'fix' the current problem
in the BigEndian tests by not testing it, making the BE code the same
as the LE version.
Fixes to pngvalid for various reduced build configurations (eliminate unused
statics) and a fix for the case in rgb_to_gray when the digitize option
reduces graylo to 0, producing a large error.
Version 1.6.21beta03 [December 18, 2015]
Widened the 'limit' check on the internally calculated error limits in
the 'DIGITIZE' case (the code used prior to 1.7 for rgb_to_gray error
checks) and changed the check to only operate in non-release builds
(base build type not RC or RELEASE.)
Fixed undefined behavior in pngvalid.c, undefined because
(png_byte) << shift is undefined if it changes the signed bit
(because png_byte is promoted to int). The libpng exported functions
png_get_uint_32 and png_get_uint_16 handle this. (Bug reported by
David Drysdale as a result of reports from UBSAN in clang 3.8).
This changes pngvalid to use BE random numbers; this used to produce
errors but these should not be fixed as a result of the previous changes.
Version 1.6.21rc01 [January 4, 2016]
In projects/vstudio, combined readme.txt and WARNING into README.txt
Version 1.6.21rc02 [January 7, 2016]
Relocated assert() in contrib/tools/pngfix.c, bug found by American
Fuzzy Lop, reported by Brian Carpenter.
Marked 'limit' UNUSED in transform_range_check(). This only affects
release builds.
Version 1.6.21 [January 15, 2016]
Worked around a false-positive Coverity issue in pngvalid.c.
Version 1.6.22beta01 [January 23, 2016]
Changed PNG_USE_MKSTEMP to __COVERITY__ to select alternate
"tmpfile()" implementation in contrib/libtests/pngstest.c
Fixed NO_STDIO build of pngunknown.c to skip calling png_init_io()
if there is no stdio.h support.
Added a png_image_write_to_memory() API and a number of assist macros
to allow an application that uses the simplified API write to bypass
stdio and write directly to memory.
Added some warnings (png.h) and some check code to detect *possible*
overflow in the ROW_STRIDE and simplified image SIZE macros. This
disallows image width/height/format that *might* overflow. This is
a quiet API change that limits in-memory image size (uncompressed) to
less than 4GByte and image row size (stride) to less than 2GByte.
Revised workaround for false-positive Coverity issue in pngvalid.c.
Version 1.6.22beta02 [February 8, 2016]
Only use exit(77) in configure builds.
Corrected error in PNG_IMAGE_PNG_SIZE_MAX. This new macro underreported
the palette size because it failed to take into account that the memory
palette has to be expanded to full RGB when it is written to PNG.
Updated CMakeLists.txt, added supporting scripts/gen*.cmake.in
and test.cmake.in (Roger Leigh).
Relaxed limit checks on gamma values in pngrtran.c. As suggested in
the comments gamma values outside the range currently permitted
by png_set_alpha_mode are useful for HDR data encoding. These values
are already permitted by png_set_gamma so it is reasonable caution to
extend the png_set_alpha_mode range as HDR imaging systems are starting
to emerge.
Version 1.6.22beta03 [March 9, 2016]
Added a common-law trademark notice and export control information
to the LICENSE file, png.h, and the man page.
Restored "& 0xff" in png_save_uint_16() and png_save_uint_32() that
were accidentally removed from libpng-1.6.17.
Changed PNG_INFO_cHNK and PNG_FREE_cHNK from 0xnnnn to 0xnnnnU in png.h
(Robert C. Seacord).
Removed dubious "#if INT_MAX" test from png.h that was added to
libpng-1.6.19beta02 (John Bowler).
Add ${INCLUDES} in scripts/genout.cmake.in (Bug report by Nixon Kwok).
Updated LICENSE to say files in the contrib directory are not
necessarily under the libpng license, and that some makefiles have
other copyright owners.
Added INTEL-SSE2 support (Mike Klein and Matt Sarett, Google, Inc.).
Made contrib/libtests/timepng more robust. The code no longer gives
up/fails on invalid PNG data, it just skips it (with error messages).
The code no longer fails on PNG files with data beyond IEND. Options
exist to use png_read_png (reading the whole image, not by row) and, in
that case, to apply any of the supported transforms. This makes for
more realistic testing; the decoded data actually gets used in a
meaningful fashion (John Bowler).
Fixed some misleading indentation (Krishnaraj Bhat).
Version 1.6.22beta04 [April 5, 2016]
Force GCC compilation to C89 if needed (Dagobert Michelsen).
SSE filter speed improvements for bpp=3:
memcpy-free implementations of load3() / store3().
call load3() only when needed at the end of a scanline.
Version 1.6.22beta05 [April 27, 2016]
Added PNG_FAST_FILTERS macro (defined as
PNG_FILTER_NONE|PNG_FILTER_SUB|PNG_FILTER_UP).
Various fixes for contrib/libtests/timepng.c
Moved INTEL-SSE code from pngpriv.h into contrib/intel/intel_sse.patch.
Fixed typo (missing underscore) in #define PNG_READ_16_TO_8_SUPPORTED
(Bug report by Y.Ohashik).
Version 1.6.22beta06 [May 5, 2016]
Rebased contrib/intel_sse.patch.
Quieted two Coverity issues in contrib/libtests/timepng.c.
Fixed issues with scripts/genout.cmake.in (David Capello, Nixon Kwok):
Added support to use multiple directories in ZLIBINCDIR variable,
Fixed CMAKE_C_FLAGS with multiple values when genout is compiled on MSVC,
Fixed pnglibconf.c compilation on OS X including the sysroot path.
Version 1.6.22rc01 [May 14, 2016]
No changes.
Version 1.6.22rc02 [May 16, 2016]
Removed contrib/timepng from default build; it does not build on platforms
that don't supply clock_gettime().
Version 1.6.22rc03 [May 17, 2016]
Restored contrib/timepng to default build but check for the presence
of clock_gettime() in configure.ac and Makefile.am.
Version 1.6.22 [May 26, 2016]
No changes.
Version 1.6.23beta01 [May 29, 2016]
Stop a potential memory leak in png_set_tRNS() (Bug report by Ted Ying).
Fixed the progressive reader to handle empty first IDAT chunk properly
(patch by Timothy Nikkel). This bug was introduced in libpng-1.6.0 and
only affected the libpng16 branch.
Added tests in pngvalid.c to check zero-length IDAT chunks in various
positions. Fixed the sequential reader to handle these more robustly
(John Bowler).
Version 1.6.23rc01 [June 2, 2016]
Corrected progressive read input buffer in pngvalid.c. The previous version
the code invariably passed just one byte at a time to libpng. The intent
was to pass a random number of bytes in the range 0..511.
Moved sse2 prototype from pngpriv.h to contrib/intel/intel_sse.patch.
Added missing ")" in pngerror.c (Matt Sarrett).
Version 1.6.23rc02 [June 4, 2016]
Fixed undefined behavior in png_push_save_buffer(). Do not call
memcpy() with a null source, even if count is zero (Leon Scroggins III).
Version 1.6.23 [June 9, 2016]
Fixed bad link to RFC2083 in png.5 (Nikola Forro).
Version 1.6.24beta01 [June 11, 2016]
Avoid potential overflow of the PNG_IMAGE_SIZE macro. This macro
is not used within libpng, but is used in some of the examples.
Version 1.6.24beta02 [June 23, 2016]
Correct filter heuristic overflow handling. This was broken when the
write filter code was moved out-of-line; if there is a single filter and
the heuristic sum overflows the calculation of the filtered line is not
completed. In versions prior to 1.6 the code was duplicated in-line
and the check not performed, so the filter operation completed; however,
in the multi-filter case where the sum is performed the 'none' filter would
be selected if all the sums overflowed, even if it wasn't in the filter
list. The fix to the first problem is simply to provide PNG_SIZE_MAX as
the current lmins sum value; this means the sum can never exceed it and
overflows silently. A reasonable compiler that does choose to inline
the code will simply eliminate the sum check.
The fix to the second problem is to use high precision arithmetic (this is
implemented in 1.7), however a simple safe fix here is to chose the lowest
numbered filter in the list from png_set_filter (this only works if the
first problem is also fixed) (John Bowler).
Use a more efficient absolute value calculation on SSE2 (Matthieu Darbois).
Fixed the case where PNG_IMAGE_BUFFER_SIZE can overflow in the application
as a result of the application using an increased 'row_stride'; previously
png_image_finish_read only checked for overflow on the base calculation of
components. (I.e. it checked for overflow of a 32-bit number on the total
number of pixel components in the output format, not the possibly padded row
length and not the number of bytes, which for linear formats is twice the
number of components.)
MSVC does not like '-(unsigned)', so replaced it with 0U-(unsigned)
MSVC does not like (uInt) = -(unsigned) (i.e. as an initializer), unless
the conversion is explicitly invoked by a cast.
Put the SKIP definition in the correct place. It needs to come after the
png.h include (see all the other .c files in contrib/libtests) because it
depends on PNG_LIBPNG_VER.
Removed the three compile warning options from the individual project
files into the zlib.props globals. It increases the warning level from 4
to All and adds a list of the warnings that need to be turned off. This is
semi-documentary; the intent is to tell libpng users which warnings have
been examined and judged non-fixable at present. The warning about
structure padding is fixable, but it would be a significant change (moving
structure members around).
Version 1.6.24beta03 [July 4, 2016]
Optimized absolute value calculation in filter selection, similar to
code in the PAETH decoder in pngrutil.c. Build with PNG_USE_ABS to
use this.
Added pngcp to the build together with a pngcp.dfa configuration test.
Added high resolution timing to pngcp.
Added "Common linking failures" section to INSTALL.
Relocated misplaced #endif in png.c sRGB profile checking.
Fixed two Coverity issues in pngcp.c.
Version 1.6.24beta04 [July 8, 2016]
Avoid filter-selection heuristic sum calculations in cases where only one
filter is a candidate for selection. This trades off code size (added
private png_setup_*_row_only() functions) for speed.
Version 1.6.24beta05 [July 13, 2016]
Fixed some indentation to comply with our coding style.
Added contrib/tools/reindent.
Version 1.6.24beta06 [July 18, 2016]
Fixed more indentation to comply with our coding style.
Eliminated unnecessary tests of boolean png_isaligned() vs 0.
Version 1.6.24rc01 [July 25, 2016]
No changes.
Version 1.6.24rc02 [August 1, 2016]
Conditionally compile SSE2 headers in contrib/intel/intel_sse.patch
Conditionally compile png_decompress_chunk().
Version 1.6.24rc03 [August 2, 2016]
Conditionally compile ARM_NEON headers in pngpriv.h
Updated contrib/intel/intel_sse.patch
Version 1.6.24[August 4, 2016]
No changes.
Version 1.6.25beta01 [August 12, 2016]
Reject oversized iCCP profile immediately.
Cleaned up PNG_DEBUG compile of pngtest.c.
Conditionally compile png_inflate().
Version 1.6.25beta02 [August 18, 2016]
Don't install pngcp; it conflicts with pngcp in the pngtools package.
Minor editing of INSTALL, (whitespace, added copyright line)
Version 1.6.25rc01 [August 24, 2016]
No changes.
Version 1.6.25rc02 [August 29, 2016]
Added MIPS support (Mandar Sahastrabuddhe ).
Only the UP filter is currently implemented.
Version 1.6.25rc03 [August 29, 2016]
Rebased contrib/intel/intel_sse.patch after the MIPS implementation.
Version 1.6.25rc04 [August 30, 2016]
Added MIPS support for SUB, AVG, and PAETH filters (Mandar Sahastrabuddhe).
Version 1.6.25rc05 [August 30, 2016]
Rebased contrib/intel/intel_sse.patch after the MIPS implementation update..
Version 1.6.25 [September 1, 2016]
No changes.
Version 1.6.26beta01 [September 26, 2016]
Fixed handling zero length IDAT in pngfix (bug report by Agostino Sarubbo,
bugfix by John Bowler).
Do not issue a png_error() on read in png_set_pCAL() because png_handle_pCAL
has allocated memory that libpng needs to free.
Conditionally compile png_set_benign_errors() in pngread.c and pngtest.c
Issue a png_benign_error instead of a png_error on ADLER32 mismatch
while decoding compressed data chunks.
Changed PNG_ZLIB_VERNUM to ZLIB_VERNUM in pngpriv.h, pngstruct.h, and
pngrutil.c.
If CRC handling of critical chunks has been set to PNG_CRC_QUIET_USE,
ignore the ADLER32 checksum in the IDAT chunk as well as the chunk CRCs.
Issue png_benign_error() on ADLER32 checksum mismatch instead of png_error().
Add tests/badcrc.png and tests/badadler.png to tests/pngtest.
Merged pngtest.c with libpng-1.7.0beta84/pngtest.c
Version 1.6.26beta02 [October 1, 2016]
Updated the documentation about CRC and ADLER32 handling.
Quieted 117 warnings from clang-3.8 in pngtrans.c, pngread.c,
pngwrite.c, pngunknown.c, and pngvalid.c.
Quieted 58 (out of 144) -Wconversion compiler warnings by changing
flag definitions in pngpriv.h from 0xnnnn to 0xnnnnU and trivial changes
in png.c, pngread.c, and pngwutil.c.
Version 1.6.26beta03 [October 2, 2016]
Removed contrib/libtests/*.orig and *.rej that slipped into the tarballs.
Quieted the 86 remaining -Wconversion compiler warnings by
revising the png_isaligned() macro and trivial changes in png.c,
pngerror.c, pngget.c, pngmem.c, pngset.c, pngrtran.c, pngrutil.c,
pngwtran.c, pngwrite.c, and pngwutil.c.
Version 1.6.26beta04 [October 3, 2016]
Quieted (bogus?) clang warnings about "absolute value has no effect"
when PNG_USE_ABS is defined.
Fixed offsets in contrib/intel/intel_sse.patch
Version 1.6.26beta05 [October 6, 2016]
Changed integer constant 4294967294 to unsigned 4294967294U in pngconf.h
to avoid a signed/unsigned compare in the preprocessor.
Version 1.6.26beta06 [October 7, 2016]
Use zlib-1.2.8.1 inflateValidate() instead of inflateReset2() to
optionally avoid ADLER32 evaluation.
Version 1.6.26rc01 [October 12, 2016]
No changes.
Version 1.6.26 [October 20, 2016]
Cosmetic change, "ptr != 0" to "ptr != NULL" in png.c and pngrutil.c
Despammed email addresses (replaced "@" with " at ").
Version 1.6.27beta01 [November 2, 2016]
Restrict the new ADLER32-skipping to IDAT chunks. It broke iCCP chunk
handling: an erroneous iCCP chunk would throw a png_error and reject the
entire PNG image instead of rejecting just the iCCP chunk with a warning,
if built with zlib-1.2.8.1.
Version 1.6.27rc01 [December 27, 2016]
Control ADLER32 checking with new PNG_IGNORE_ADLER32 option. Fixes
an endless loop when handling erroneous ADLER32 checksums; bug
introduced in libpng-1.6.26.
Removed the use of a macro containing the pre-processor 'defined'
operator. It is unclear whether this is valid; a macro that
"generates" 'defined' is not permitted, but the use of the word
"generates" within the C90 standard seems to imply more than simple
substitution of an expression itself containing a well-formed defined
operation.
Added ARM support to CMakeLists.txt (Andreas Franek).
Version 1.6.27 [December 29, 2016]
Fixed a potential null pointer dereference in png_set_text_2() (bug report
and patch by Patrick Keshishian, CVE-2016-10087).
Version 1.6.28rc01 [January 3, 2017]
Fixed arm/aarch64 detection in CMakeLists.txt (Gianfranco Costamagna).
Added option to Cmake build allowing a custom location of zlib to be
specified in a scenario where libpng is being built as a subproject
alongside zlib by another project (Sam Serrels).
Changed png_ptr->options from a png_byte to png_uint_32, to accommodate
up to 16 options.
Version 1.6.28rc02 [January 4, 2017]
Added "include(GNUInstallDirs)" to CMakeLists.txt (Gianfranco Costamagna).
Moved SSE2 optimization code into the main libpng source directory.
Configure libpng with "configure --enable-intel-sse" or compile
libpng with "-DPNG_INTEL_SSE" in CPPFLAGS to enable it.
Version 1.6.28rc03 [January 4, 2017]
Backed out the SSE optimization and last CMakeLists.txt to allow time for QA.
Version 1.6.28 [January 5, 2017]
No changes.
Version 1.6.29beta01 [January 12, 2017]
Readded "include(GNUInstallDirs)" to CMakeLists.txt (Gianfranco Costamagna).
Moved SSE2 optimization code into the main libpng source directory.
Configure libpng with "configure --enable-intel-sse" or compile
libpng with "-DPNG_INTEL_SSE" in CPPFLAGS to enable it.
Simplified conditional compilation in pngvalid.c, for AIX (Michael Felt).
Version 1.6.29beta02 [February 22, 2017]
Avoid conditional directives that break statements in pngrutil.c (Romero
Malaquias)
The contrib/examples/pngtopng.c recovery code was in the wrong "if"
branches; the comments were correct.
Added code for PowerPC VSX optimisation (Vadim Barkov).
Version 1.6.29beta03 [March 1, 2017]
Avoid potential overflow of shift operations in png_do_expand() (Aaron Boxer).
Change test ZLIB_VERNUM >= 0x1281 to ZLIB_VERNUM >= 0x1290 in pngrutil.c
because Solaris 11 distributes zlib-1.2.8.f that is older than 1.2.8.1,
as suggested in zlib FAQ, item 24.
Suppress clang warnings about implicit sign changes in png.c
Version 1.6.29 [March 16, 2017]
No changes.
Version 1.6.30beta01 [April 1, 2017]
Added missing "$(CPPFLAGS)" to the compile line for c.pic.o in
makefile.linux and makefile.solaris-x86 (Cosmin).
Revised documentation of png_get_error_ptr() in the libpng manual.
Silence clang -Wcomma and const drop warnings (Viktor Szakats).
Update Sourceforge URLs in documentation (https instead of http).
Version 1.6.30beta02 [April 22, 2017]
Document need to check for integer overflow when allocating a pixel
buffer for multiple rows in contrib/gregbook, contrib/pngminus,
example.c, and in the manual (suggested by Jaeseung Choi). This
is similar to the bug reported against pngquant in CVE-2016-5735.
Removed reference to the obsolete PNG_SAFE_LIMITS macro in the documentation.
Version 1.6.30beta03 [May 22, 2017]
Check for integer overflow in contrib/visupng and contrib/tools/genpng.
Do not double evaluate CMAKE_SYSTEM_PROCESSOR in CMakeLists.txt.
Test CMAKE_HOST_WIN32 instead of WIN32 in CMakeLists.txt.
Fix some URL in documentation.
Version 1.6.30beta04 [June 7, 2017]
Avoid writing an empty IDAT when the last IDAT exactly fills the
compression buffer (bug report by Brian Baird). This bug was
introduced in libpng-1.6.0.
Version 1.6.30rc01 [June 14, 2017]
No changes.
Version 1.6.30rc02 [June 25, 2017]
Update copyright year in pnglibconf.h, make ltmain.sh executable.
Add a reference to the libpng.download site in README.
Version 1.6.30 [June 28, 2017]
No changes.
Version 1.6.31beta01 [July 5, 2017]
Guard the definition of _POSIX_SOURCE in pngpriv.h (AIX already defines it;
bug report by Michael Felt).
Revised pngpriv.h to work around failure to compile arm/filter_neon.S
("typedef" directive is unrecognized by the assembler). The problem
was introduced in libpng-1.6.30beta01.
Added "Requires: zlib" to libpng.pc.in (Pieter Neerincx).
Added special case for FreeBSD in arm/filter_neon.S (Maya Rashish).
Version 1.6.31beta02 [July 8, 2017]
Added instructions for disabling hardware optimizations in INSTALL.
Added "--enable-hardware-optimizations" configuration flag to enable
or disable all hardware optimizations with one flag.
Version 1.6.31beta03 [July 9, 2017]
Updated CMakeLists.txt to add INTEL_SSE and MIPS_MSA platforms.
Changed "int" to "png_size_t" in intel/filter_sse2.c to prevent
possible integer overflow (Bug report by John Bowler).
Quieted "declaration after statement" warnings in intel/filter_sse2.c.
Added scripts/makefile-linux-opt, which has hardware optimizations enabled.
Version 1.6.31beta04 [July 11, 2017]
Removed one of the GCC-7.1.0 'strict-overflow' warnings that result when
integers appear on both sides of a compare. Worked around the others by
forcing the strict-overflow setting in the relevant functions to a level
where they are not reported (John Bowler).
Changed "FALL THROUGH" comments to "FALLTHROUGH" because GCC doesn't like
the space.
Worked around some C-style casts from (void*) because g++ 5.4.0 objects
to them.
Increased the buffer size for 'sprint' to pass the gcc 7.1.0 'sprint
overflow' check that is on by default with -Wall -Wextra.
Version 1.6.31beta05 [July 13, 2017]
Added eXIf chunk support.
Version 1.6.31beta06 [July 17, 2017]
Added a minimal eXIf chunk (with Orientation and FocalLengthIn35mmFilm
tags) to pngtest.png.
Version 1.6.31beta07 [July 18, 2017]
Revised the eXIf chunk in pngtest.png to fix "Bad IFD1 Directory" warning.
Version 1.6.31rc01 [July 19, 2017]
No changes.
Version 1.6.31rc02 [July 25, 2017]
Fixed typo in example.c (png_free_image should be png_image_free) (Bug
report by John Smith)
Version 1.6.31 [July 27, 2017]
No changes.
Version 1.6.32beta01 [July 31, 2017]
Avoid possible NULL dereference in png_handle_eXIf when benign_errors
are allowed. Avoid leaking the input buffer "eXIf_buf".
Eliminated png_ptr->num_exif member from pngstruct.h and added num_exif
to arguments for png_get_eXIf() and png_set_eXIf().
Added calls to png_handle_eXIf(() in pngread.c and png_write_eXIf() in
pngwrite.c, and made various other fixes to png_write_eXIf().
Changed name of png_get_eXIF and png_set_eXIf() to png_get_eXIf_1() and
png_set_eXIf_1(), respectively, to avoid breaking API compatibility
with libpng-1.6.31.
Version 1.6.32beta02 [August 1, 2017]
Updated contrib/libtests/pngunknown.c with eXIf chunk.
Version 1.6.32beta03 [August 2, 2017]
Initialized btoa[] in pngstest.c
Stop memory leak when returning from png_handle_eXIf() with an error
(Bug report from the OSS-fuzz project).

Replaced local eXIf_buf with info_ptr-eXIf_buf in png_handle_eXIf().
Update libpng.3 and libpng-manual.txt about eXIf functions.
Version 1.6.32beta05 [August 2, 2017]
Restored png_get_eXIf() and png_set_eXIf() to maintain API compatibility.
Version 1.6.32beta06 [August 2, 2017]
Removed png_get_eXIf_1() and png_set_eXIf_1().
Version 1.6.32beta07 [August 3, 2017]
Check length of all chunks except IDAT against user limit to fix an
OSS-fuzz issue (Fixes CVE-2017-12652).
Version 1.6.32beta08 [August 3, 2017]
Check length of IDAT against maximum possible IDAT size, accounting
for height, rowbytes, interlacing and zlib/deflate overhead.
Restored png_get_eXIf_1() and png_set_eXIf_1(), because strlen(eXIf_buf)
does not work (the eXIf chunk data can contain zeroes).
Version 1.6.32beta09 [August 3, 2017]
Require cmake-2.8.8 in CMakeLists.txt. Revised symlink creation,
no longer using deprecated cmake LOCATION feature (Clifford Yapp).
Fixed five-byte error in the calculation of IDAT maximum possible size.
Version 1.6.32beta10 [August 5, 2017]
Moved chunk-length check into a png_check_chunk_length() private
function (Suggested by Max Stepin).
Moved bad pngs from tests to contrib/libtests/crashers
Moved testing of bad pngs into a separate tests/pngtest-badpngs script
Added the --xfail (expected FAIL) option to pngtest.c. It writes XFAIL
in the output but PASS for the libpng test.
Require cmake-3.0.2 in CMakeLists.txt (Clifford Yapp).
Fix "const" declaration info_ptr argument to png_get_eXIf_1() and the
num_exif argument to png_get_eXIf_1() (Github Issue 171).
Version 1.6.32beta11 [August 7, 2017]
Added "eXIf" to "chunks_to_ignore[]" in png_set_keep_unknown_chunks().
Added huge_IDAT.png and empty_ancillary_chunks.png to testpngs/crashers.
Make pngtest --strict, --relax, --xfail options imply -m (multiple).
Removed unused chunk_name parameter from png_check_chunk_length().
Relocated setting free_me for eXIf data, to stop an OSS-fuzz leak.
Initialize profile_header[] in png_handle_iCCP() to fix OSS-fuzz issue.
Initialize png_ptr->row_buf[0] to 255 in png_read_row() to fix OSS-fuzz UMR.
Attempt to fix a UMR in png_set_text_2() to fix OSS-fuzz issue.
Increase minimum zlib stream from 9 to 14 in png_handle_iCCP(), to account
for the minimum 'deflate' stream, and relocate the test to a point
after the keyword has been read.
Check that the eXIf chunk has at least 2 bytes and begins with "II" or "MM".
Version 1.6.32rc01 [August 18, 2017]
Added a set of "huge_xxxx_chunk.png" files to contrib/testpngs/crashers,
one for each known chunk type, with length = 2GB-1.
Check for 0 return from png_get_rowbytes() and added some (size_t) typecasts
in contrib/pngminus/*.c to stop some Coverity issues (162705, 162706,
and 162707).
Renamed chunks in contrib/testpngs/crashers to avoid having files whose
names differ only in case; this causes problems with some platforms
(github issue #172).
Version 1.6.32rc02 [August 22, 2017]
Added contrib/oss-fuzz directory which contains files used by the oss-fuzz
project (https://github.com/google/oss-fuzz/tree/master/projects/libpng).
Version 1.6.32 [August 24, 2017]
No changes.
Version 1.6.33beta01 [August 28, 2017]
Added PNGMINUS_UNUSED macro to contrib/pngminus/p*.c and added missing
parenthesis in contrib/pngminus/pnm2png.c (bug report by Christian Hesse).
Fixed off-by-one error in png_do_check_palette_indexes() (Bug report
by Mick P., Source Forge Issue #269).
Version 1.6.33beta02 [September 3, 2017]
Initialize png_handler.row_ptr in contrib/oss-fuzz/libpng_read_fuzzer.cc
to fix shortlived oss-fuzz issue 3234.
Compute a larger limit on IDAT because some applications write a deflate
buffer for each row (Bug report by Andrew Church).
Use current date (DATE) instead of release-date (RDATE) in last
changed date of contrib/oss-fuzz files.
Enabled ARM support in CMakeLists.txt (Bernd Kuhls).
Version 1.6.33beta03 [September 14, 2017]
Fixed incorrect typecast of some arguments to png_malloc() and
png_calloc() that were png_uint_32 instead of png_alloc_size_t
(Bug report by "irwir" in Github libpng issue #175).
Use pnglibconf.h.prebuilt when building for ANDROID with cmake (Github
issue 162, by rcdailey).
Version 1.6.33rc01 [September 20, 2017]
Initialize memory allocated by png_inflate to zero, using memset, to
stop an oss-fuzz "use of uninitialized value" detection in png_set_text_2()
due to truncated iTXt or zTXt chunk.
Initialize memory allocated by png_read_buffer to zero, using memset, to
stop an oss-fuzz "use of uninitialized value" detection in
png_icc_check_tag_table() due to truncated iCCP chunk.
Removed a redundant test (suggested by "irwir" in Github issue #180).
Version 1.6.33rc02 [September 23, 2017]
Added an interlaced version of each file in contrib/pngsuite.
Relocate new memset() call in pngrutil.c.
Removed more redundant tests (suggested by "irwir" in Github issue #180).
Add support for loading images with associated alpha in the Simplified
API (Samuel Williams).

Revert contrib/oss-fuzz/libpng_read_fuzzer.cc to libpng-1.6.32 state.
Initialize png_handler.row_ptr in contrib/oss-fuzz/libpng_read_fuzzer.cc
Add end_info structure and png_read_end() to the libpng fuzzer.
Version 1.6.34 [September 29, 2017]
Removed contrib/pngsuite/i*.png; some of them caused test failures.
Version 1.6.35beta01 [March 6, 2018]
Restored 21 of the contrib/pngsuite/i*.png, which do not cause test
failures. Placed the remainder in contrib/pngsuite/interlaced/i*.png.
Added calls to png_set_*() transforms commonly used by browsers to
the fuzzer.

Version 1.6.35 [July 15, 2018]
Replaced the remaining uses of png_size_t with size_t (Cosmin)
Fixed the calculation of row_factor in png_check_chunk_length
(reported by Thuan Pham in SourceForge issue #278)

I. Simple installation
On Unix/Linux and similar systems, you can simply type
./configure [--prefix=/path]
make check
make install
and ignore the rest of this document. "/path" is the path to the directory
where you want to install the libpng "lib", "include", and "bin"
subdirectories.
If you downloaded a GIT clone, you will need to run ./autogen.sh before
running ./configure, to create "configure" and "Makefile.in" which are
not included in the GIT repository.
Note that "configure" is only included in the "*.tar" distributions and not
in the "*.zip" or "*.7z" distributions. If you downloaded one of those
distributions, see "Building with project files" or "Building with makefiles",
below.
II. Rebuilding the configure scripts
If configure does not work on your system, or if you have a need to
change configure.ac or Makefile.am, and you have a reasonably
up-to-date set of tools, running ./autogen.sh in a git clone before
running ./configure may fix the problem. To be really sure that you
aren't using any of the included pre-built scripts, especially if you
are building from a tar distribution instead of a git distribution,
do this:
./configure --enable-maintainer-mode
make maintainer-clean
./autogen.sh --maintainer --clean
./autogen.sh --maintainer
./configure [--prefix=/path] [other options]
make
make install
make check
III. Using scripts/makefile*
Instead, you can use one of the custom-built makefiles in the
"scripts" directory
cp scripts/pnglibconf.h.prebuilt pnglibconf.h
cp scripts/makefile.system makefile
make test
make install
The files that are presently available in the scripts directory
are listed and described in scripts/README.txt.
Or you can use one of the "projects" in the "projects" directory.
Before installing libpng, you must first install zlib, if it
is not already on your system. zlib can usually be found
wherever you got libpng; otherwise go to https://zlib.net/. You can
place zlib in the same directory as libpng or in another directory.
If your system already has a preinstalled zlib you will still need
to have access to the zlib.h and zconf.h include files that
correspond to the version of zlib that's installed.
If you wish to test with a particular zlib that is not first in the
standard library search path, put ZLIBLIB, ZLIBINC, CPPFLAGS, LDFLAGS,
and LD_LIBRARY_PATH in your environment before running "make test"
or "make distcheck":
ZLIBLIB=/path/to/lib export ZLIBLIB
ZLIBINC=/path/to/include export ZLIBINC
CPPFLAGS="-I$ZLIBINC" export CPPFLAGS
LDFLAGS="-L$ZLIBLIB" export LDFLAGS
LD_LIBRARY_PATH="$ZLIBLIB:$LD_LIBRARY_PATH" export LD_LIBRARY_PATH
If you are using one of the makefile scripts, put ZLIBLIB and ZLIBINC
in your environment and type
make ZLIBLIB=$ZLIBLIB ZLIBINC=$ZLIBINC test
IV. Using cmake
If you want to use "cmake" (see www.cmake.org), type
cmake . -DCMAKE_INSTALL_PREFIX=/path
make
make install
As when using the simple configure method described above, "/path" points to
the installation directory where you want to put the libpng "lib", "include",
and "bin" subdirectories.
V. Directory structure
You can rename the directories that you downloaded (they
might be called "libpng-x.y.z" or "libpngNN" and "zlib-1.2.8"
or "zlib128") so that you have directories called "zlib" and "libpng".
Your directory structure should look like this:
.. (the parent directory)
libpng (this directory)
INSTALL (this file)
README
*.h, *.c => libpng source files
CMakeLists.txt => "cmake" script
configuration files:
configure.ac, configure, Makefile.am, Makefile.in,
autogen.sh, config.guess, ltmain.sh, missing, libpng.pc.in,
libpng-config.in, aclocal.m4, config.h.in, config.sub,
depcomp, install-sh, mkinstalldirs, test-pngtest.sh
contrib
arm-neon, conftest, examples, gregbook, libtests, pngminim,
pngminus, pngsuite, tools, visupng
projects
cbuilder5, owatcom, visualc71, vstudio, xcode
scripts
makefile.*
*.def (module definition files)
etc.
pngtest.png
etc.
zlib
README, *.h, *.c contrib, etc.
If the line endings in the files look funny, you may wish to get the other
distribution of libpng. It is available in both tar.gz (UNIX style line
endings) and zip (DOS style line endings) formats.
VI. Building with project files
If you are building libpng with MSVC, you can enter the
libpng projects\visualc71 or vstudio directory and follow the instructions
in README.txt.
Otherwise enter the zlib directory and follow the instructions in zlib/README,
then come back here and run "configure" or choose the appropriate
makefile.sys in the scripts directory.
VII. Building with makefiles
Copy the file (or files) that you need from the
scripts directory into this directory, for example
MSDOS example:
copy scripts\makefile.msc makefile
copy scripts\pnglibconf.h.prebuilt pnglibconf.h
UNIX example:
cp scripts/makefile.std makefile
cp scripts/pnglibconf.h.prebuilt pnglibconf.h
Read the makefile to see if you need to change any source or
target directories to match your preferences.
Then read pnglibconf.dfa to see if you want to make any configuration
changes.
Then just run "make" which will create the libpng library in
this directory and "make test" which will run a quick test that reads
the "pngtest.png" file and writes a "pngout.png" file that should be
identical to it. Look for "9782 zero samples" in the output of the
test. For more confidence, you can run another test by typing
"pngtest pngnow.png" and looking for "289 zero samples" in the output.
Also, you can run "pngtest -m contrib/pngsuite/*.png" and compare
your output with the result shown in contrib/pngsuite/README.
Most of the makefiles will allow you to run "make install" to
put the library in its final resting place (if you want to
do that, run "make install" in the zlib directory first if necessary).
Some also allow you to run "make test-installed" after you have
run "make install".
VIII. Configuring libpng for 16-bit platforms
You will want to look into zconf.h to tell zlib (and thus libpng) that
it cannot allocate more than 64K at a time. Even if you can, the memory
won't be accessible. So limit zlib and libpng to 64K by defining MAXSEG_64K.
IX. Configuring for DOS
For DOS users who only have access to the lower 640K, you will
have to limit zlib's memory usage via a png_set_compression_mem_level()
call. See zlib.h or zconf.h in the zlib library for more information.
X. Configuring for Medium Model
Libpng's support for medium model has been tested on most of the popular
compilers. Make sure MAXSEG_64K gets defined, USE_FAR_KEYWORD gets
defined, and FAR gets defined to far in pngconf.h, and you should be
all set. Everything in the library (except for zlib's structure) is
expecting far data. You must use the typedefs with the p or pp on
the end for pointers (or at least look at them and be careful). Make
note that the rows of data are defined as png_bytepp, which is
an "unsigned char far * far *".
XI. Prepending a prefix to exported symbols
Starting with libpng-1.6.0, you can configure libpng (when using the
"configure" script) to prefix all exported symbols by means of the
configuration option "--with-libpng-prefix=FOO_", where FOO_ can be any
string beginning with a letter and containing only uppercase
and lowercase letters, digits, and the underscore (i.e., a C language
identifier). This creates a set of macros in pnglibconf.h, so this is
transparent to applications; their function calls get transformed by
the macros to use the modified names.
XII. Configuring for compiler xxx:
All includes for libpng are in pngconf.h. If you need to add, change
or delete an include, this is the place to do it.
The includes that are not needed outside libpng are placed in pngpriv.h,
which is only used by the routines inside libpng itself.
The files in libpng proper only include pngpriv.h and png.h, which
in turn includes pngconf.h and, as of libpng-1.5.0, pnglibconf.h.
As of libpng-1.5.0, pngpriv.h also includes three other private header
files, pngstruct.h, pnginfo.h, and pngdebug.h, which contain material
that previously appeared in the public headers.
XIII. Removing unwanted object code
There are a bunch of #define's in pngconf.h that control what parts of
libpng are compiled. All the defines end in _SUPPORTED. If you are
never going to use a capability, you can change the #define to #undef
before recompiling libpng and save yourself code and data space, or
you can turn off individual capabilities with defines that begin with
"PNG_NO_".
In libpng-1.5.0 and later, the #define's are in pnglibconf.h instead.
You can also turn all of the transforms and ancillary chunk capabilities
off en masse with compiler directives that define
PNG_NO_READ[or WRITE]_TRANSFORMS, or PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS,
or all four, along with directives to turn on any of the capabilities that
you do want. The PNG_NO_READ[or WRITE]_TRANSFORMS directives disable the
extra transformations but still leave the library fully capable of reading
and writing PNG files with all known public chunks. Use of the
PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS directive produces a library
that is incapable of reading or writing ancillary chunks. If you are
not using the progressive reading capability, you can turn that off
with PNG_NO_PROGRESSIVE_READ (don't confuse this with the INTERLACING
capability, which you'll still have).
All the reading and writing specific code are in separate files, so the
linker should only grab the files it needs. However, if you want to
make sure, or if you are building a stand alone library, all the
reading files start with "pngr" and all the writing files start with "pngw".
The files that don't match either (like png.c, pngtrans.c, etc.)
are used for both reading and writing, and always need to be included.
The progressive reader is in pngpread.c
If you are creating or distributing a dynamically linked library (a .so
or DLL file), you should not remove or disable any parts of the library,
as this will cause applications linked with different versions of the
library to fail if they call functions not available in your library.
The size of the library itself should not be an issue, because only
those sections that are actually used will be loaded into memory.
XIV. Enabling or disabling hardware optimizations
Certain hardware capabilities, such as the Intel SSE instructions,
are normally detected at run time. Enable them with configure options
such as one of
--enable-arm-neon=yes
--enable-mips-msa=yes
--enable-intel-sse=yes
--enable-powerpc-vsx=yes
or enable them all at once with
--enable-hardware-optimizations=yes
or, if you are not using "configure", you can use one
or more of
CPPFLAGS += "-DPNG_ARM_NEON"
CPPFLAGS += "-DPNG_MIPS_MSA"
CPPFLAGS += "-DPNG_INTEL_SSE"
CPPFLAGS += "-DPNG_POWERPC_VSX"
See for example scripts/makefile.linux-opt
If you wish to avoid using them,
you can disable them via the configure option
--disable-hardware-optimizations
to disable them all, or
--enable-intel-sse=no
to disable a particular one,
or via compiler-command options such as
CPPFLAGS += "-DPNG_ARM_NEON_OPT=0, -DPNG_MIPS_MSA_OPT=0,
-DPNG_INTEL_SSE_OPT=0, -DPNG_POWERPC_VSX_OPT=0"
If you are using cmake, hardware optimizations are "on"
by default. To disable them, use
cmake . -DPNG_ARM_NEON=no -DPNG_INTEL_SSE=no \
-DPNG_MIPS_MSA=no -DPNG_POWERPC_VSX=no
or disable them all at once with
cmake . -DPNG_HARDWARE_OPTIMIZATIONS=no
XV. Changes to the build and configuration of libpng in libpng-1.5.x
Details of internal changes to the library code can be found in the CHANGES
file and in the GIT repository logs. These will be of no concern to the vast
majority of library users or builders; however, the few who configure libpng
to a non-default feature set may need to change how this is done.
There should be no need for library builders to alter build scripts if
these use the distributed build support - configure or the makefiles -
however, users of the makefiles may care to update their build scripts
to build pnglibconf.h where the corresponding makefile does not do so.
Building libpng with a non-default configuration has changed completely.
The old method using pngusr.h should still work correctly even though the
way pngusr.h is used in the build has been changed; however, library
builders will probably want to examine the changes to take advantage of
new capabilities and to simplify their build system.
A. Specific changes to library configuration capabilities
The exact mechanism used to control attributes of API functions has
changed. A single set of operating system independent macro definitions
is used and operating system specific directives are defined in
pnglibconf.h
As part of this the mechanism used to choose procedure call standards on
those systems that allow a choice has been changed. At present this only
affects certain Microsoft (DOS, Windows) and IBM (OS/2) operating systems
running on Intel processors. As before, PNGAPI is defined where required
to control the exported API functions; however, two new macros, PNGCBAPI
and PNGCAPI, are used instead for callback functions (PNGCBAPI) and
(PNGCAPI) for functions that must match a C library prototype (currently
only png_longjmp_ptr, which must match the C longjmp function.) The new
approach is documented in pngconf.h
Despite these changes, libpng 1.5.0 only supports the native C function
calling standard on those platforms tested so far ("__cdecl" on Microsoft
Windows). This is because the support requirements for alternative
calling conventions seem to no longer exist. Developers who find it
necessary to set PNG_API_RULE to 1 should advise the mailing list
(png-mng-implement) of this and library builders who use Openwatcom and
therefore set PNG_API_RULE to 2 should also contact the mailing list.
B. Changes to the configuration mechanism
Prior to libpng-1.5.0 library builders who needed to configure libpng
had either to modify the exported pngconf.h header file to add system
specific configuration or had to write feature selection macros into
pngusr.h and cause this to be included into pngconf.h by defining
PNG_USER_CONFIG. The latter mechanism had the disadvantage that an
application built without PNG_USER_CONFIG defined would see the
unmodified, default, libpng API and thus would probably fail to link.
These mechanisms still work in the configure build and in any makefile
build that builds pnglibconf.h, although the feature selection macros
have changed somewhat as described above. In 1.5.0, however, pngusr.h is
processed only once, at the time the exported header file pnglibconf.h is
built. pngconf.h no longer includes pngusr.h; therefore, pngusr.h is ignored
after the build of pnglibconf.h and it is never included in an application
build.
The formerly used alternative of adding a list of feature macros to the
CPPFLAGS setting in the build also still works; however, the macros will be
copied to pnglibconf.h and this may produce macro redefinition warnings
when the individual C files are compiled.
All configuration now only works if pnglibconf.h is built from
scripts/pnglibconf.dfa. This requires the program awk. Brian Kernighan
(the original author of awk) maintains C source code of that awk and this
and all known later implementations (often called by subtly different
names - nawk and gawk for example) are adequate to build pnglibconf.h.
The Sun Microsystems (now Oracle) program 'awk' is an earlier version
and does not work; this may also apply to other systems that have a
functioning awk called 'nawk'.
Configuration options are now documented in scripts/pnglibconf.dfa. This
file also includes dependency information that ensures a configuration is
consistent; that is, if a feature is switched off, dependent features are
also switched off. As a recommended alternative to using feature macros in
pngusr.h a system builder may also define equivalent options in pngusr.dfa
(or, indeed, any file) and add that to the configuration by setting
DFA_XTRA to the file name. The makefiles in contrib/pngminim illustrate
how to do this, and also illustrate a case where pngusr.h is still required.
After you have built libpng, the definitions that were recorded in
pnglibconf.h are available to your application (pnglibconf.h is included
in png.h and gets installed alongside png.h and pngconf.h in your
$PREFIX/include directory). Do not edit pnglibconf.h after you have built
libpng, because than the settings would not accurately reflect the settings
that were used to build libpng.
XVI. Setjmp/longjmp issues
Libpng uses setjmp()/longjmp() for error handling. Unfortunately setjmp()
is known to be not thread-safe on some platforms and we don't know of
any platform where it is guaranteed to be thread-safe. Therefore, if
your application is going to be using multiple threads, you should
configure libpng with PNG_NO_SETJMP in your pngusr.dfa file, with
-DPNG_NO_SETJMP on your compile line, or with
#undef PNG_SETJMP_SUPPORTED
in your pnglibconf.h or pngusr.h.
Starting with libpng-1.6.0, the library included a "simplified API".
This requires setjmp/longjmp, so you must either build the library
with PNG_SETJMP_SUPPORTED defined, or with PNG_SIMPLIFIED_READ_SUPPORTED
and PNG_SIMPLIFIED_WRITE_SUPPORTED undefined.
XVII. Common linking failures
If your application fails to find libpng or zlib entries while linking:
Be sure "-lz" appears after "-lpng" on your linking command.
Be sure you have built libpng, zlib, and your application for the
same platform (e.g., 32-bit or 64-bit).
If you are using the vstudio project, observe the WARNING in
project/vstudio/README.txt.
XVIII. Other sources of information about libpng:

=================================================
See the note about version numbers near the top of png.h.
See INSTALL for instructions on how to install libpng.
Libpng comes in several distribution formats. Get libpng-*.tar.gz or
libpng-*.tar.xz or if you want UNIX-style line endings in the text
files, or lpng*.7z or lpng*.zip if you want DOS-style line endings.
Version 0.89 was the first official release of libpng. Don't let the
fact that it's the first release fool you. The libpng library has been
in extensive use and testing since mid-1995. By late 1997 it had
finally gotten to the stage where there hadn't been significant
changes to the API in some time, and people have a bad feeling about
libraries with versions < 1.0. Version 1.0.0 was released in
March 1998.
****
Note that some of the changes to the png_info structure render this
version of the library binary incompatible with libpng-0.89 or
earlier versions if you are using a shared library. The type of the
"filler" parameter for png_set_filler() has changed from png_byte to
png_uint_32, which will affect shared-library applications that use
this function.
To avoid problems with changes to the internals of the png info_struct,
new APIs have been made available in 0.95 to avoid direct application
access to info_ptr. These functions are the png_set_ and
png_get_ functions. These functions should be used when
accessing/storing the info_struct data, rather than manipulating it
directly, to avoid such problems in the future.
It is important to note that the APIs did not make current programs
that access the info struct directly incompatible with the new
library, through libpng-1.2.x. In libpng-1.4.x, which was meant to
be a transitional release, members of the png_struct and the
info_struct can still be accessed, but the compiler will issue a
warning about deprecated usage. Since libpng-1.5.0, direct access
to these structs is not allowed, and the definitions of the structs
reside in private pngstruct.h and pnginfo.h header files that are not
accessible to applications. It is strongly suggested that new
programs use the new APIs (as shown in example.c and pngtest.c), and
older programs be converted to the new format, to facilitate upgrades
in the future.
****
Additions since 0.90 include the ability to compile libpng as a
Windows DLL, and new APIs for accessing data in the info struct.
Experimental functions include the ability to set weighting and cost
factors for row filter selection, direct reads of integers from buffers
on big-endian processors that support misaligned data access, faster
methods of doing alpha composition, and more accurate 16->8 bit color
conversion.
The additions since 0.89 include the ability to read from a PNG stream
which has had some (or all) of the signature bytes read by the calling
application. This also allows the reading of embedded PNG streams that
do not have the PNG file signature. As well, it is now possible to set
the library action on the detection of chunk CRC errors. It is possible
to set different actions based on whether the CRC error occurred in a
critical or an ancillary chunk.
For a detailed description on using libpng, read libpng-manual.txt.
For examples of libpng in a program, see example.c and pngtest.c. For
usage information and restrictions (what little they are) on libpng,
see png.h. For a description on using zlib (the compression library
used by libpng) and zlib's restrictions, see zlib.h
I have included a general makefile, as well as several machine and
compiler specific ones, but you may have to modify one for your own
needs.
You should use zlib 1.0.4 or later to run this, but it MAY work with
versions as old as zlib 0.95. Even so, there are bugs in older zlib
versions which can cause the output of invalid compression streams for
some images.
You should also note that zlib is a compression library that is useful
for more things than just PNG files. You can use zlib as a drop-in
replacement for fread() and fwrite(), if you are so inclined.
zlib should be available at the same place that libpng is, or at
https://zlib.net.
You may also want a copy of the PNG specification. It is available
as an RFC, a W3C Recommendation, and an ISO/IEC Standard. You can find
these at http://www.libpng.org/pub/png/pngdocs.html .
This code is currently being archived at libpng.sourceforge.io in the
[DOWNLOAD] area, and at http://libpng.download/src .
This release, based in a large way on Glenn's, Guy's and Andreas'
earlier work, was created and will be supported by myself and the PNG
development group.

# This file is free software; the Free Software Foundation

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is '.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

# AM_PROG_INSTALL_STRIP
# ---------------------
# One issue with vendor 'install' (even GNU) is that you can't
# specify the program used to strip binaries. This is especially
# annoying in cross-compiling environments, where the build's strip
# is unlikely to handle the host's binaries.
# Fortunately install-sh will honor a STRIPPROG variable, so we
# always use install-sh in "make install-strip", and initialize
# STRIPPROG with the value of the STRIP variable (set by the user).

# run "make install-strip". However 'strip' might not be the right

# This file is supposed to be the same for all GNU packages
# and recognize all the CPU types, system types and aliases
# that are meaningful with *any* GNU software.
# Each package is responsible for reporting which valid configurations
# it does not support. The user should be able to distinguish
# a failure to support a valid configuration from a meaningless
# configuration.
# The goal of this file is to map all the various variations of a given
# machine specification into a single specification in the form:
# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
# or in some cases, the newer four-part form:
# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
# It is wrong to echo any other type of specification.

\`configure' configures libpng 1.6.37 to adapt to many kinds of systems.
Usage: $0 [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print \`checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for \`--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or \`..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[$ac_default_prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]

Optional Features:
--disable-option-checking ignore unrecognized --enable/--with options
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--enable-silent-rules less verbose build output (undo: "make V=1")
--disable-silent-rules verbose build output (undo: "make V=0")
--enable-maintainer-mode
enable make rules and dependencies not useful (and
sometimes confusing) to the casual installer
--enable-dependency-tracking
do not reject slow dependency extractors
--disable-dependency-tracking
speeds up one-time build
--enable-shared[=PKGS] build shared libraries [default=yes]
--enable-static[=PKGS] build static libraries [default=yes]
--enable-fast-install[=PKGS]
optimize for fast installation [default=yes]
--disable-libtool-lock avoid locking (might break parallel builds)
--enable-werror[=OPT] Pass -Werror or the given argument to the compiler
if it is supported
--enable-unversioned-links
Installed libpng header files are placed in a
versioned subdirectory and installed libpng library
(including DLL) files are versioned. If this option
is enabled unversioned links will be created
pointing to the corresponding installed files. If
you use libpng.pc or libpng-config for all builds
you do not need these links, but if you compile
programs directly they will typically #include
and link with -lpng; in that case you need
the links. The links can be installed manually using
'make install-header-links' and 'make
install-library-links' and can be removed using the
corresponding uninstall- targets. If you do enable
this option every libpng 'make install' will
recreate the links to point to the just installed
version of libpng. The default is to create the
links; use --disable-unversioned-links to change
this
--enable-unversioned-libpng-pc
Install the configuration file 'libpng.pc' as a link
to the versioned version. This is done by default -
use --disable-unversioned-libpng-pc to change this.
--enable-unversioned-libpng-config
Install the configuration file 'libpng-config' as a
link to the versioned version. This is done by
default - use --disable-unversioned-libpng-config to
change this.
--enable-hardware-optimizations
Enable hardware optimizations: =no/off, yes/on:
--enable-arm-neon Enable ARM NEON optimizations: =no/off, check, api,
yes/on: no/off: disable the optimizations; check:
use internal checking code (deprecated and poorly
supported); api: disable by default, enable by a
call to png_set_option; yes/on: turn on
unconditionally. If not specified: determined by the
compiler.
--enable-mips-msa Enable MIPS MSA optimizations: =no/off, check, api,
yes/on: no/off: disable the optimizations; check:
use internal checking code (deprecated and poorly
supported); api: disable by default, enable by a
call to png_set_option; yes/on: turn on
unconditionally. If not specified: determined by the
compiler.
--enable-intel-sse Enable Intel SSE optimizations: =no/off, yes/on:
no/off: disable the optimizations; yes/on: enable
the optimizations. If not specified: determined by
the compiler.
--enable-powerpc-vsx Enable POWERPC VSX optimizations: =no/off, check,
api, yes/on: no/off: disable the optimizations;
check: use internal checking code api: disable by
default, enable by a call to png_set_option yes/on:
turn on unconditionally. If not specified:
determined by the compiler.
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
--with-pic[=PKGS] try to use only PIC/non-PIC objects [default=use
both]
--with-aix-soname=aix|svr4|both
shared library versioning (aka "SONAME") variant to
provide on AIX, [default=aix].
--with-sysroot[=DIR] Search for dependent libraries within DIR (or the
compiler's sysroot if not specified).
--with-zlib-prefix prefix that may have been used in installed zlib
--with-pkgconfigdir Use the specified pkgconfig dir (default is
libdir/pkgconfig)
--with-binconfigs Generate shell libpng-config scripts as well as
pkg-config data [default=yes]
--with-libpng-prefix prefix libpng exported function (API) names with the
given value
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L if you have libraries in a
nonstandard directory
LIBS libraries to pass to the linker, e.g. -l
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if
you have headers in a nonstandard directory
CCAS assembler compiler command (defaults to CC)
CCASFLAGS assembler compiler flags (defaults to CFLAGS)
CPP C preprocessor
LT_SYS_LIBRARY_PATH
User-defined run-time library search path.
PNG_COPTS additional flags for the C compiler, use this for options that
would cause configure itself to fail
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

Oops!
Your 'rm' program seems unable to run without file operands specified
on the command line, even when the '-f' option is present. This is contrary
to the behaviour of most rm programs out there, and not conforming with
the upcoming POSIX standard:
Please tell bug-automake@gnu.org about your system, including the value
of your $PATH and any error possibly output before this message. This
can help us improve future automake versions.

Aborting the configuration process, to ensure you take notice of the issue.
You can download and install GNU coreutils to get an 'rm' implementation
that behaves properly: .
If you want to complete the configuration process using your problematic
'rm' anyway, export the environment variable ACCEPT_INFERIOR_RM_PROGRAM
to "yes", and re-run configure.

This "contrib" directory contains contributions which are not necessarily under
the libpng license, although all are open source. They are not part of
libpng proper and are not used for building the library, although some are used
for testing the library via "make check".
3p-libpng-m1/libpng/contrib/arm-neon/ 0000775 0000000 0000000 00000000000 14174313134 0017614 5 ustar 00root root 0000000 0000000 3p-libpng-m1/libpng/contrib/arm-neon/README 0000664 0000000 0000000 00000006575 14174313134 0020511 0 ustar 00root root 0000000 0000000 OPERATING SYSTEM SPECIFIC ARM NEON DETECTION
--------------------------------------------
Detection of the ability to execute ARM NEON on an ARM processor requires
operating system support. (The information is not available in user mode.)
HOW TO USE THIS
---------------
This directory contains C code fragments that can be included in arm/arm_init.c
by setting the macro PNG_ARM_NEON_FILE to the file name in "" or <> at build
time. This setting is not recorded in pnglibconf.h and can be changed simply by
rebuilding arm/arm_init.o with the required macro definition.
For any of this code to be used the ARM NEON code must be enabled and run time
checks must be supported. I.e.:
#if PNG_ARM_NEON_OPT > 0
#ifdef PNG_ARM_NEON_CHECK_SUPPORTED
This is done in a 'configure' build by passing configure the argument:
--enable-arm-neon=check
Apart from the basic Linux implementation in contrib/arm-neon/linux.c this code
is unsupported. That means that it is not even compiled on a regular basis and
may be broken in any given minor release.
FILE FORMAT
-----------
Each file documents its testing status as of the last time it was tested (which
may have been a long time ago):
STATUS: one of:
SUPPORTED: This indicates that the file is included in the regularly
performed test builds and bugs are fixed when discovered.
COMPILED: This indicates that the code did compile at least once. See the
more detailed description for the extent to which the result was
successful.
TESTED: This means the code was fully compiled into the libpng test programs
and these were run at least once.
BUG REPORTS: an email address to which to send reports of problems
The file is a fragment of C code. It should not define any 'extern' symbols;
everything should be static. It must define the function:
static int png_have_neon(png_structp png_ptr);
That function must return 1 if ARM NEON instructions are supported, 0 if not.
It must not execute png_error unless it detects a bug. A png_error will prevent
the reading of the PNG and in the future, writing too.
BUG REPORTS
-----------
If you mail a bug report for any file that is not SUPPORTED there may only be
limited response. Consider fixing it and sending a patch to fix the problem -
this is more likely to result in action.
CONTRIBUTIONS
-------------
You may send contributions of new implementations to
png-mng-implement@sourceforge.net. Please write code in strict C90 C where
possible. Obviously OS dependencies are to be expected. If you submit code you
must have the authors permission and it must have a license that is acceptable
to the current maintainer; in particular that license must permit modification
and redistribution.
Please try to make the contribution a single file and give the file a clear and
unambiguous name that identifies the target OS. If multiple files really are
required put them all in a sub-directory.
You must also be prepared to handle bug reports from users of the code, either
by joining the png-mng-implement mailing list or by providing an email for the
"BUG REPORTS" entry or both. Please make sure that the header of the file
contains the STATUS and BUG REPORTS fields as above.
Please list the OS requirements as precisely as possible. Ideally you should
also list the environment in which the code has been tested and certainly list
any environments where you suspect it might not work.

intended to be used in the build by setting the make macro DFA_XTRA to the name
of the file.
These files are used in release validation of the 'configure' builds of libpng
by building 'make check', or 'make all-am' for cross-builds, with each .dfa
file.
The files in this directory may change between minor releases, however
contributions describing specific builds of libpng are welcomed. There is no
guarantee that libpng will continue to build with such configurations; support
for given configurations can be, and has been, dropped between successive minor
releases. However if a .dfa file describing a configuration is not in this
directory it is very unlikely that it will be tested before a minor release!
You can use these .dfa files as the basis of new configurations. Files in this
directory should not have any use restrictions or restrictive licenses.
This directory is not included in the .zip and .7z distributions, which do
not contain 'configure' scripts.

FILE NAMING
===========
File names in this directory may NOT contain any of the five characters:
- , + * ?
Neither may they contain any space character.
While other characters may be used it is strongly suggested that file names be
limited to lower case Latiin alphabetic characters (a-z), digits (0-9) and, if
necessary the underscore (_) character. File names should be about 8 characters
long (excluding the .dfa extension). Submitted .dfa files should have names
between 7 and 16 characters long, shorter names (6 characters or less) are
reserved for standard tests.

# Build libpng with support for pngcp. This means just png_read_png,
# png_write_png and small number of configuration settings.
#
everything = off
# This option is specific to this configuration; it adds a #define to the
# generated pnglibconf.h which turns on the (not portable) timing option for
# pngcp. Note that any option is automatically preceded by PNG_; there is no
# way round this and this is deliberate.
option PNGCP_TIMING
# Because of the everything off above the option must also be turned on. This
# may not be done in one step because it is safer and avoids mis-spelled options
# in user .dfa files to error out if an unrecognized option is turned on.
option PNGCP_TIMING on
# Options to turn on png_read_png and png_write_png:
option INFO_IMAGE on
option SEQUENTIAL_READ on
option EASY_ACCESS on
option WRITE on
option WRITE_16BIT on
option WRITE_FILTER on
# pngcp needs this to preserve unknown chunks, switching all these on means that
# pngcp can work without explicit known chunk reading support
option UNKNOWN_CHUNKS on
option SET_UNKNOWN_CHUNKS on
option HANDLE_AS_UNKNOWN on
option SAVE_UNKNOWN_CHUNKS on
option WRITE_UNKNOWN_CHUNKS on
# pngcp needs this to handle palette files with invalid indices:
option CHECK_FOR_INVALID_INDEX on
option GET_PALETTE_MAX on
# Pre-libpng 1.7 pngcp has to stash text chunks manually, post 1.7 without this
# text chunks should be handled as unknown ok.
option TEXT on
# this is used to turn off limits:
option USER_LIMITS on
option SET_USER_LIMITS on
# these are just required for specific customizations
option WRITE_CUSTOMIZE_ZTXT_COMPRESSION on

# Build libpng with basic read support. This enables the lowest level libpng
# read API - the one where the calling code has to use a loop to read each row.
# At present this is the API used by most programs.
#
# Support is enabled only for those chunks and transformations that are
# typically required - others can be added easily.
#
everything = off
# The sequential read code is enabled here; the progressive code can be used
# instead but there is no point enabling both.
option SEQUENTIAL_READ on
# Likewise it is pointless enabling both fixed and floating point APIs. Choose
# one or the other for both the API and the internal math.
#Fixed point:
#option FIXED_POINT on
#option FLOATING_ARITHMETIC off
#Floating point:
option FLOATING_POINT on

option SETJMP on

option USER_MEM on
# To read the full set of PNG images correctly interlace, transparency and
# 16-bit support is required. The application can implement interlace itself,
# but very few do and it's no longer possible to disable it when READ is
# enabled.
option READ_tRNS on
option READ_16BIT on
# Everything else is application dependent. This file assumes the app handles
# all the native PNG bit layouts, so it doesn't need any of layout change
# transforms, but needs libpng to perform gamma correction. It doesn't do any
# colorspace stuff and ignores the 'significant bit' information.
#
# If your app always expands the image to a limited set of bit layouts you
# probably want to consider using the simplified API instead of the low level
# one - see png.h and s_read.dfa.

# Choose fixed or floating point APIs and arithmetic. The choices are
