0f08665bfb [libpng16] Imported from libpng-1.6.0beta27.tar 2012-08-11 18:31:44 -05:00

aa9dea57d7 [libpng16] Work around gcc 3.x and Microsoft Visual Studio 2010 complaints. 
Both object to the split initialization of num_chunks.

ece07cfe9c [libpng16] Removed the png_sizeof(), png_strlen(), png_memset(), png_memcpy(), 
and png_memcmp() macros.

dbb7e19fda [libpng16] Consistently use memset(), memcpy(), and memcmp() instead of the 
png_memset(), png_memcpy(), and png_memcmp() macros.

e2098ba085 [libpng16] 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.

26849f4693 [libpng16] Consistently use png_memset(), png_memcpy(), and png_memcmp(), 
except in pngtest.c and example.c where these macros are not visible.

ad5a993954 [libpng16] 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).

865e14fd32 [libpng16] Revised comments about info_ptr->signature, added CHANGES entry. 2012-08-10 08:05:53 -05:00

8d3453a22d [libpng16] 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.

dff6f4c4f0 [libpng16Cleanup 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.

432c174b64 [libpng16] Eliminated use of png_sizeof(); use sizeof() instead, and use. 
a consistent style for (sizeof type) and (sizeof (array))
 2012-08-09 20:14:48 -05:00
John Bowler
5f5977e708 [libpng16] Re-eliminated the use of strcpy() in pngtest.c. An unncessary use 
of strcpy() was accidentally re-introduced in libpng16; this change replaces
it with strncpy().

0a9f8eb272 [libpng16] 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.

01b813000a [libpng16] Removed references to png_zalloc() and png_zfree() from the manual. 
They have not been exported to applications since libpng12.

5845d3eabd [libpng16] Removed scripts/makefile.cegcc from the *.zip and *.7z 
distributions; it depends on configure, which is not included in those
archives.

4a37149f66 [libpng16] Bump version to 1.6.0beta26 2012-06-16 14:50:34 -05:00
Glenn Randers-Pehrson
96b917056d [libpng16] 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.

0546e4e579 [libpng16] Document deprecation of png_convert_to_rfc1123() and its

905cc94e3d [libpng16] Don't check palette indexes if num_palette is 0 (as it can be in 
MNG files).

14ca47b453 [libpng16] 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.

b1e7771d5e [libpng16] Do not depend upon a GCC feature macro being available for use in 
generating the linker mapfile symbol prefix.

ff7b7ba060 [libpng16] 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.

b45416921b [libpng16] 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 clang warns about either (pngread.c) by eliminating the
casts from png_bytep to png_uint_16p 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.

cd39adb561 [libpng16] Removed #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED in pngpriv.h around

b4f5c42092 [libpng16] 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 (Toby Thain).

921648a997 [libpng16] Recognize known sRGB ICC profiles while reading; prefer writing the

8fbd60ded2 [libpng16] Recognize known sRGB ICC profiles while reading and handle them as

eda53e5770 [libpng16] Avoid the double gamma correction warning in the simplified API. 
This allows the --strict option to pass in the pngstest checks
 2012-03-18 22:46:28 -05:00

2bc76ffaf1 [ibpng16] 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.

66efa24241 [libpng16] 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.
