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

f260f6d156 [libpng16] Protect symbol prefixing against CC/CPPFLAGS/CFLAGS useage. 
Previous iOS/Xcode fixes for the ARM NEON optimizations moved the test
on __ARM_NEON__ from configure time to compile time.  This breaks symbol
prefixing because the definition of the special png_init_filter_functions
call was hidden at configure time if the relevant compiler arguments are
passed in CFLAGS as opposed to CC.  This change attempts to avoid all
the confusion that would result by declaring the init function even when
it is not used, so that it will always get prefixed.

18dd07e3e6 [libpng16] Removed PNG_FILTER_OPTIMIZATIONS and PNG_ARM_NEON_SUPPORTED from 
pnglibconf.h, allowing more of the decisions to be made internally
(pngpriv.h) during the compile.  Without this, symbol prefixing is broken
under certain circumstances on ARM platforms.  Now only the API parts of
the optimizations ('check' vs 'api') are exposed in the public header files
except that the new setting PNG_ARM_NEON_OPT documents how libpng makes the
decision about whether or not to use the optimizations.

aa22442a9c [libpng16] Make ARM NEON support work at compile time (not just configure time). 
This moves the test on __ARM_NEON__ into pngconf.h to avoid issues when
using a compiler that compiles for multiple architectures at one time.

3f2b5a6670 libpng16] Updated contrib/pngminus/pnm2png.c (Paul Stewart):

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.

62c6fbbd29 [libpng16] Check that PNG_MAXIMUM_INFLATE_WINDOW is defined before using it. 2013-05-07 23:16:06 -05:00
John Bowler
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).
