a74b70871c [libpng16] Ensure that NEON filter stuff is completely disabled when 
switched 'off'.  Previously the ARM NEON specific files were still built
if the option was switched 'off' as opposed to being explicitly disabled.

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.
 2013-04-17 21:27:47 -05:00
Glenn Randers-Pehrson
7fdb594e73 [libpng16] Added #ifdef PNG_WRITE_sRGB_SUPPORTED, etc., tests where needed in 
png_image_write_main() in pngwrite.c (bug report from Yuriy Levchenko).

f1736a636b [libpng16] Added contrib/tools/fixitxt.c, to repair the erroneous iTXt 
chunk length written by libpng-1.6.0 and 1.6.1.

Glenn Randers-Pehrson
364acf40aa [libpng16] Corrected a misplaced closing bracket in contrib/libtests/pngvalid.c 
(Flavio Medeiros).
 2013-04-13 11:55:08 -05:00
John Bowler
b44cd59ad9 [libpng16] Corrected the test on user transform changes on read. It was in the 
png_set of the transform function, but that doesn't matter unless the
transform function changes the rowbuf size, and that is only valid if
transform_info is called.
 2013-04-12 22:15:54 -05:00
John Bowler
43c07e1b48 [libpng16] Fixed incorrect warning of excess deflate data. End condition - the 
warning would be produced if the end of the deflate stream wasn't read
in the last row.  The warning is harmless.
 2013-04-07 21:33:30 -05:00
Glenn Randers-Pehrson
2e0c5f0dff [libpng16] Updated documentation of 1.5.x to 1.6.x changes in iCCP chunk 
handling.

caa3f296df [libpng16] Eliminated another warning from the Intel C compiler. 2013-03-10 21:40:27 -05:00
John Bowler
2286a7cef4 [libpng16] Eliminated a warning from the Intel C compiler. The warning is 
technically valid, although a reasonable treatment of division would
show it to be incorrect.

Glenn Randers-Pehrson
3c8b422b0a [libpng16] Bump version to 1.6.1beta09 2013-03-07 11:36:55 -06:00

0645b62528 [libpng16] Imported from libpng-1.6.1beta08.tar 2013-03-07 11:36:47 -06:00
Claudio Bley
0281dee877 [libpng16] Fixed CMakelists.txt to allow building a single variant of the 
library (Claudio Bley):
  Introduced a PNG_LIB_TARGETS variable that lists all activated library
    targets.  It is an error if this variable ends up empty, ie. you have
    to build at least one library variant.
  Made the *_COPY targets only depend on library targets actually being build.
  Use PNG_LIB_TARGETS to unify a code path.
  Changed the CREATE_SYMLINK macro to expact the full path to a file as the
    first argument. When symlinking the filename component of that path is
    determined and used as the link target.
  Use copy_if_different in the CREATE_SYMLINK macro.

e55b25a962 [libpng16] Bump version to 1.6.1beta08 2013-03-06 22:42:23 -06:00
John Bowler
59ae38984f [libpng16] Corrected simplified API default gamma for color-mapped output, added 
a flag to change default. In 1.6.0 when the simplified API was used
to produce color-mapped output from an input image with no gamma
information the gamma assumed for the input could be different from
that assumed for non-color-mapped output.  In particular 16-bit depth
input files were assumed to be sRGB encoded, whereas in the 'direct'
case they were assumed to have linear data.  This was an error.  The
fix makes the simplified API treat all input files the same way and
adds a new flag to the png_image::flags member to allow the
application/user to specify that 16-bit files contain sRGB data
rather than the default linear.
Fixed bugs in the pngpixel and makepng test programs.

1cbfa24a93 [libpng16] Bump version to 1.6.1beta07 2013-03-04 17:56:59 -06:00
John Bowler
f3728100d9 [libpng16] Corrected Android builds and corrected libpng.vers with symbol 
prefixing This adds an API to set optimization options externally,
    providing an alternative and general solution for the non-portable
    run-time tests used by the ARM Neon code.  It also makes those tests
    compile and link on Android.
  The order of settings vs options in pnglibconf.h is reversed to allow
    settings to depend on options and options can now set (or override) the
    defaults for settings.
 2013-03-04 16:26:31 -06:00
John Bowler
e15b537825 [libpng16] Better documentation of unknown handling API interactions. 2013-03-02 17:59:43 -06:00

Glenn Randers-Pehrson
96cf4bde0e [libpng16] Fixed bug introduced in libpng-1.6.0beta28 that causes libpng to 
handle chunks even when they have been tagged PNG_HANDLE_CHUNK_NEVER.
 2013-03-01 20:04:06 -06:00

f8a8ead5cb [libpng16] Update the INSTALL document. 2013-02-22 16:52:21 -06:00
John Bowler
09a5ca72ac [libpng16] Allow run-time ARM NEON checking to be disabled. A new configure 
option:
    --enable-arm-neon=always will stop the run-time checks. New checks
    within arm/arm_init.c will cause the code not to be compiled unless
    __ARM_NEON__ is set. This should make it fail safe (if someone asks
    for it on then the build will fail if it can't be done.)
Fixed ALIGNED_MEMORY support.

765d145ec4 [libpng16] Use approved/supported Android method to check for NEON, use 
Linux/POSIX 1003.1 API to check /proc/self/auxv avoiding buffer allocation
and other library calls (ported from libpng15).

John Bowler
b724c812ec [libpng16] Enabled parallel tests - back ported from libpng-1.7. 2013-02-16 00:05:59 -06:00
John Bowler
0695fcd834 [libpng16] Removed cc -E workround, corrected png_get_palette_max API Tested on SUN OS cc 5.9, 
which demonstrates the tokenization problem previously avoided by using /lib/cpp.
Since all .dfn output is now protected in double quotes unless it is to be macro
substituted the fix should work everywhere.
 2013-02-15 23:46:37 -06:00
John Bowler
42835d3d19 [libpng16] Ported libpng 1.5 options.awk/dfn file handling to 1.6, fixed one bug. 2013-02-15 23:40:34 -06:00
John Bowler
2d99978f67 [libpng16] Made sRGB check numbers consistent. 2013-02-15 23:25:18 -06:00
John Bowler
9d2e875826 [libpng16] Made symbol prefixing work with the ARM neon optimizations. Also allow pngpriv.h 
to be included for preprocessor definitions only, so it can be used in non-C/C++
files. Back ported from libpng 1.7.

d000fb89c0 [libpng16] Enclosed the new png_get_palette_max 
in #ifdef PNG_GET_PALETTE_MAX_SUPPORTED block, and revised pnglibconf.h
and pnglibconf.h.prebuilt accordingly.

9fabbedcf3 [libpng16] Bump version to 1.6.0rc07 2013-02-09 07:44:06 -06:00
John Bowler
b8d0534e9d [libpng16] Fixed missing dependency in --prefix builds The intermediate 
internal 'prefix.h' file can only be generated correctly after
pnglibconf.h, however the dependency was not in Makefile.am.  The
symptoms are unpredictable depending on the order make chooses to
build pngprefix.h and pnglibconf.h, often the error goes unnoticed
because there is a system pnglibconf.h to use instead.

John Bowler
e9d616321a [libpng16] Fixed Windows build issues, enabled ARM compilation. Various warnings issued 
by earlier versions of GCC fixed for Cygwin and Min/GW (which both use old GCCs.)
ARM support is enabled by default in zlib.props (unsupported by Microsoft) and
ARM compilation is made possible by deleting the check for x86. The test programs
cannot be run because they are not signed.
 2012-12-20 22:48:58 -06:00
John Bowler
24639a63ce [libpng16] Made default Zlib compression settings be configurable. This adds #defines to
