Version 1.5.15 [March 28, 2013]
|

|
No changes.
|
||||||
|
|
||||||
|
Version 1.5.16beta01 [April 25, 2013]
|
||||||
|
Corrected a misplaced closing bracket in contrib/libtests/pngvalid.c
|
||||||
|
(Flavio Medeiros).
|
||||||
|
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.
|
||||||
|
Avoid a compiler warning about unused png_ptr in translate_gamma_flags()
|
||||||
|
|
||||||
|
Version 1.5.16beta02 [April 26, 2013]
|
||||||
|
Revise pngtest.c to skip tests of unsupported features.
|
||||||
|
Regenerated configure files.
|
||||||
|
|
||||||
|
Version 1.5.16beta03 [April 26, 2013]
|
||||||
|
Test for 'arm*' not just 'arm' in the host_cpu configure variable.
|
||||||
|
|
||||||
|
Version 1.5.16beta04 [May 1, 2013]
|
||||||
|
Expanded manual paragraph about writing private chunks, particularly
|
||||||
|
the need to call png_set_keep_unknown_chunks() when writing them.
|
||||||
|
|
||||||
|
Version 1.5.16beta05 [May 9, 2013]
|
||||||
|
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.
|
||||||
|
|
||||||
|
Version 1.5.16beta06 [May 12, 2013]
|
||||||
|
Allow contrib/pnminus/pnm2png.c to compile without WRITE_INVERT and WRITE_PACK
|
||||||
|
supported (writes error message that it can't read P1 or P4 PBM files).
|
||||||
|
Revised contrib/pngminim/*/makefile to separate CPPFLAGS and CFLAGS, and
|
||||||
|
to generate pnglibconf.h with the right zlib header files.
|
||||||
|
Ported contrib/pngminus/pnm2png.c changes back from libpng-1.6.3beta06,
|
||||||
|
to use unsigned long, not png_uint_32 arguments to sscanf().
|
||||||
