Changes since the last public release (1.6.2):
|
|
|
|
Version 1.6.3beta01 [April 25, 2013]
|
|
Revised stack marking in arm/filter_neon.S and configure.ac.
|
|
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.
|
|
|
|
Version 1.6.3beta02 [April 26, 2013]
|
|
Test for 'arm*' not just 'arm' in the host_cpu configure variable.
|
|
Rebuilt the configure scripts.
|
|
|
|
Version 1.6.3beta03 [April 30, 2013]
|
|
Expanded manual paragraph about writing private chunks, particularly
|
|
the need to call png_set_keep_unknown_chunks() when writing them.
|
|
Avoid dereferencing NULL pointer possibly returned from
|
|
png_create_write_struct() (Andrew Church).
|
|
|
|
Version 1.6.3beta05 [May 9, 2013]
|
|
Calculate our own zlib windowBits when decoding rather than trusting the
|
|
CMF bytes in the PNG datastream.
|
|
Added an option to force maximum window size for inflating, which was
|
|
the behavior of libpng15 and earlier.
|
|
Added png-fix-itxt and png-fix-too-far-back to the built programs and
|
|
removed warnings from the source code and timepng that are revealed as
|
|
a result.
|
|
Detect wrong libpng versions linked to png-fix-too-far-back, 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.
|
|
Updated contrib/pngminus/pnm2png.c (Paul Stewart):
|
|
Check for EOF
|
|
Ignore "#" delimited comments in input file to pnm2png.c.
|
|
Fixed whitespace handling
|
|
Added a call to png_set_packing()
|
|
Initialize dimension values so if sscanf fails at least we have known
|
|
invalid values.
|
|
Attempt to detect configuration issues with png-fix-too-far-back, which
|
|
requires both the correct libpng and the correct zlib to function
|
|
correctly.
|
|
Check ZLIB_VERNUM for mismatches, enclose #error in quotes
|
|
Added information in the documentation about problems with and fixes for
|
|
the bad CRC and bad iTXt chunk situations.
