0441ff62e7 [libpng16] Remove spurious "#ifdef PNG_sRGB_SUPPORTED" from pngrutil.c 2013-10-04 19:28:48 -05:00

b3721757a0 [libpng16] Catch up with some recent changes that did not get merged. 2013-09-30 13:56:44 -05:00

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).

Glenn Randers-Pehrson
6f8f004fe1 [libpng16] Added #ifdef PNG_READ_SUPPORTED/endif around the 
png_chunk_unknown_handling() function, and restored the unknown-chunk
handling code from libpng-1.6.6.

Glenn Randers-Pehrson
bc8e40d611 [libpng16] Added "/* SAFE */" comments in pngrutil.c and pngrtran.c 
where warnings may be erroneously issued by code-checking applications.
Revised manual about changes in iTXt chunk handling made in libpng-1.6.0.

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

John Bowler
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).

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.

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.

520803d57e [libpng16] Removed non-working ICC profile support code. There was too much 
code for too little gain; implementing full ICC color correction is maybe
desireable but is left up to applications.
