cd39adb561 [libpng16] Removed #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED in pngpriv.h around 
declaration of png_handle_unknown().

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.

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.

John Bowler
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.

f5dcba6b9b [libpng16] Never mind, undid previous change. 2012-03-17 00:21:45 -05:00

c26d6e9aac [libpng16] Revised png_set_text_2() to avoid possible memory corruption 
when writing.

42ed02ed9a [libpng16] Reverted png_set_itxt(); it would not compile without warnings. 2012-03-16 23:17:27 -05:00
Glenn Randers-Pehrson
31d66245ea [libpng16] Added png_set_itxt() (work in progress) 2012-03-16 13:53:25 -05:00

dd6ecbe688 [libpng16] Imported from libpng-1.6.0beta18.tar v1.6.0beta18 2012-03-16 08:34:31 -05:00
John Bowler
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.

845ee6af72 [libpng16] Fixed a compiler warning under Cygwin (Windows-7, 32-bit system) 2012-03-10 21:05:19 -06:00

9ff37ea94f [libpng16] Fix an off-by-one error in the palette index checking function. 2012-03-10 20:03:06 -06:00
Glenn Randers-Pehrson
35f2e1768b [libpng16] In pngtest, treat benign errors as errors if "-strict" is present. 2012-03-10 19:42:03 -06:00
Glenn Randers-Pehrson
945cb1f9be [libpng16] Issue a png_benign_error() instead of png_warning() about bad 
palette index.

9066919600 [libpng16] 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.
 2012-03-09 22:03:13 -06:00

1ffbe8c7c1 [libpng] Committed new contrib/libtests/makepng.c that was overlooked 
in a recent patch.

8d0215928d [libpng16] Fixed manual assertion that all of our public macros begin with PNG_ 
Some such as PNGAPI begin with "PNG".
 2012-03-09 12:18:18 -06:00
John Bowler
b5d0051dcb [libpng16] 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.

6038b80277 [libpng16] Reject iCCP chunk after the first, even if the first one is invalid. 2012-03-08 10:40:07 -06:00

6225b0e61e [libpng16] 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).

d072048925 [libpng16] Correct pngvalid error message 2012-03-05 21:10:11 -06:00

7d4fbb2fbb [libpng16] Validate the zTXt strings in pngvalid. 2012-03-05 21:02:49 -06:00
John Bowler
42a2b556e9 [libpng16] 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.
