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.

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

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.

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 
iCCP profile over writing the sRGB chunk, controlled by the
    PNG_sRGB_PROFILE_CHECKS option.

about it, if PNG_WARN_IF_iCCP_IS_sRGB_SUPPORTED is defined.

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
John Bowler
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.
 2012-03-18 22:37:25 -05:00
John Bowler
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.

0c11b5f8e7 [libpng16] 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.

42ed02ed9a [libpng16] Reverted png_set_itxt(); it would not compile without warnings. 2012-03-16 23:17:27 -05:00

aa816c4444 [libpng16] 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 errors (regardless of the system default, unless
this is disabled in which case the simplified API can't be built.)

209b3e4b79 [libpng16] Added output flushing to aid debugging under Visual Studio. 
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!)
 2012-03-16 07:14:01 -05:00
Glenn Randers-Pehrson
f2715a558a [libpng16] 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.
