1fc0171278 [libpng16] 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

0f6303301f [libpng16] 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().
 2013-11-22 18:49:58 -06:00

503a49458b [libpng16] Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder. 2013-11-22 15:16:04 -06:00
Glenn Randers-Pehrson
c912050a7b [libpng16] 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.

a7f0bcb3a6 [libpng16] Added "-Wall" to CFLAGS in contrib/pngminim/*/makefile 2013-11-18 17:07:26 -06:00
John Bowler
08b0620202 [libpng16] Fixed #include in filter_neon_intrinsics.c and ctype macros. The 
ctype char checking macros take an unsigned char argument, not a signed char.
 2013-11-04 13:44:37 -06:00
John Bowler
9e9977e153 [libpng16] Revised pngvalid to generate size images with as many filters as 
it can manage, limited by the number of rows.
 2013-10-17 08:23:13 -05:00
John Bowler
236e105170 [libpng16] 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).
 2013-10-04 20:28:33 -05:00
John Bowler
5b1df53a82 [libpng16] 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
 2013-10-04 20:13:17 -05:00
John Bowler
cc93d89e43 [libpng16] Updated pngunknown.c 2013-09-30 13:07:58 -05:00
John Bowler
8f381901e3 [libpng16] 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

15a80443de [libpng16] 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).

b4ec1f8451 [libpng16] Unified pngfix.c source with libpng17. 2013-07-02 23:47:57 -05:00
John Bowler
f5f1206778 [libpng16] 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

573c9d434f [libpng16] Change "png-fix-too-far-back" to "pngfix" inside pngfix.c

John Bowler
870beb5279 [libng16] Revised contrib/tools/png-fix-too-far-back.c to check all compressed 
chunks known to libpng.

ff141eb21e [libpng16] Renamed contrib/tools/fixitxt to contrib/tools/png-fix-itxt. 
Added information in the documentation about problems with and fixes for
the bad CRC and bad iTXt chunk situations.

9afb90f885 [libpng16] Attempt to detect configuration issues with pngdeflate, 
which requires both the correct libpng and the correct zlib to function
correctly.

3f2b5a6670 libpng16] Updated contrib/pngminus/pnm2png.c (Paul Stewart): 
Fixed whitespace handling
Added a call to png_set_packing()
Initialize dimension values so if sscanf fails at least we have known
   invalid values.

294d0b8408 [libpng16] Detect wrong libpng versions linked to pngdeflate, 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.

0c7ac064d3 [libpng16] Added an option to force maximum window size for inflating. 
For inflate, reverted previous fixes.
Added fixitxt and pngdeflate to the built programs and removed warnings
from the source code and timepng that are revealed as a result.  Fixed
fixitxt when the chunk length is more than 65535 (untested, no test case).

db67cba8d4 [libpng16] Check for EOF in contrib/pngminus/pnm2png.c (Paul Stewart).

e4413a735b [libpng16] Disallow storing sRGB information when the sRGB is not supported. 
Reverted previous attempt to allow gAMA and sRGB non-support with the
simplified API.
