3744f94fd1 [libpng16] Removed trailing blanks 2012-08-10 19:22:53 -05:00
John Bowler
aa9dea57d7 [libpng16] Work around gcc 3.x and Microsoft Visual Studio 2010 complaints. 
Both object to the split initialization of num_chunks.
 2012-08-10 19:04:08 -05:00
Glenn Randers-Pehrson
ece07cfe9c [libpng16] Removed the png_sizeof(), png_strlen(), png_memset(), png_memcpy(), 
and png_memcmp() macros.
 2012-08-10 18:19:41 -05:00
Glenn Randers-Pehrson
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.
 2012-08-10 16:01:45 -05:00
John Bowler
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).
 2012-08-10 13:15:07 -05:00
Glenn Randers-Pehrson
6954141484 [libpng16] Add more conditionals for compiling png_fixed(). 
This is a small function, but avoiding compiling it also avoids needing
to link with "-lm" unnecessarily.
 2012-08-10 12:56:57 -05:00

ba2dd33d9c [libpng16] Some files were omitted from a previous checkin. Here they are. 2012-08-10 10:58:01 -05:00
John Bowler
134c5761fa [libpng16] Fix new leak when text compression is disabled. 2012-08-10 10:49:21 -05:00
John Bowler
865e14fd32 [libpng16] Revised comments about info_ptr->signature, added CHANGES entry. 2012-08-10 08:05:53 -05:00
Glenn Randers-Pehrson
5d1df4fdf4 [libpng16] Removed png_get_signature() and info_ptr->signature from WRITE-only 
builds.  Restored png_get_channels() to WRITE-only builds.
 2012-08-10 07:49:44 -05:00
John Bowler
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.
 2012-08-09 22:57:35 -05:00
Glenn Randers-Pehrson
4430b91363 [libpng16] Restore info_ptr members that were deleted by the previous 
patch; they are needed by png_set_IHDR() for both read and write.  Fix
some ifdefs that caused the contrib/pngminim/ applications to not compile.
 2012-08-09 22:24:04 -05:00
John Bowler
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().
 2012-08-09 16:42:42 -05:00
John Bowler
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.

cad0150d12 [libpng16] Corrected handling of row_pointers in example.c and added some 
comments.  It has apparently been wrong since libpng-1.0.1c (confusing
use of a 1D and a 2D array for the image source).
 2012-08-08 21:11:55 -05:00

ee427ad39a [libpng16] Add information about png_calloc() to the manual. 2012-08-03 08:39:54 -05:00
Glenn Randers-Pehrson
01b813000a [libpng16] Removed references to png_zalloc() and png_zfree() from the manual. 
They have not been exported to applications since libpng12.

449db5a9c1 [libpng16] Check for existence of __GNUC_MINOR__ before testing its value 
(This is probably unnecessary because it's inside a __GNUC__ block.)
 2012-07-21 13:18:42 -05:00
Glenn Randers-Pehrson
80b67e47e8 [libpng16] Added default blank "#define PNG_RESTRICT" to pngconf.h 
This has been missing since the feature was introduced in libpng-1.6.0beta04.

0a9f26e219 [libpng16] Do not use __restrict when GNUC is <= 3.1 2012-07-21 11:16:17 -05:00

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

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.
 2012-06-03 19:30:02 -05:00
Glenn Randers-Pehrson
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.

15f6fd3492 [libpng16] checked in contrib/libtests/pngstest.c which was omitted 2012-04-30 13:59:58 -05:00
John Bowler
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.
