Changes since the last public release (1.6.16):
|
|
|
|
Removed duplicate PNG_SAFE_LIMITS_SUPPORTED handling from pngconf.h
|
|
Corrected the width limit calculation in png_check_IHDR().
|
|
Removed user limits from pngfix. Also pass NULL pointers to
|
|
png_read_row to skip the unnecessary row de-interlace stuff.
|
|
Added testing of png_set_packing() to pngvalid.c
|
|
Regenerated configure scripts in the *.tar distributions with libtool-2.4.4
|
|
Implement previously untested cases of libpng transforms in pngvalid.c
|
|
Fixed byte order in 2-byte filler, in png_do_read_filler().
|
|
Made the check for out-of-range values in png_set_tRNS() detect
|
|
values that are exactly 2^bit_depth, and work on 16-bit platforms.
|
|
Merged some parts of libpng-1.6.17beta01 and libpng-1.7.0beta47.
|
|
Added #ifndef __COVERITY__ where needed in png.c, pngrutil.c and
|
|
pngset.c to avoid warnings about dead code.
|
|
Do not build png_product2() when it is unused.
|
|
Display user limits in the output from pngtest.
|
|
Eliminated the PNG_SAFE_LIMITS macro and restored the 1-million-column
|
|
and 1-million-row default limits in pnglibconf.dfa, that can be reset
|
|
by the user at build time or run time. This provides a more robust
|
|
defense against DOS and as-yet undiscovered overflows.
|
|
Added PNG_WRITE_CUSTOMIZE_COMPRESSION_SUPPORTED macro, on by default.
|
|
Allow user to call png_get_IHDR() with NULL arguments (Reuben Hawkins).
|
|
Rebuilt configure scripts with automake-1.15 and libtool-2.4.6
|
|
Moved png_set_filter() prototype into a PNG_WRITE_SUPPORTED block
|
|
of png.h.
|
|
Avoid runtime checks when converting integer to png_byte with
|
|
Visual Studio (Sergey Kosarevsky)
|
|
Removed some comments that the configure script did not handle
|
|
properly from scripts/pnglibconf.dfa and pnglibconf.h.prebuilt.
|
|
Free the unknown_chunks structure even when it contains no data.
|
|
Updated CMakeLists.txt to add OSX framework, change YES/NO to ON/OFF
|
|
for consistency, and remove some useless tests (Alexey Petruchik).
|
|
Remove pnglibconf.h, pnglibconf.c, pnglibconf.pre, pnglibconf.dfn,
|
|
and pnglibconf.out instead of pnglibconf.* in "make clean" (Cosmin).
|
|
Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha
|
|
value was wrong. It's not clear if this affected the final stored
|
|
value; in the obvious code path the upper and lower 8-bits of the
|
|
alpha value were identical and the alpha was truncated to 8-bits
|
|
rather than dividing by 257 (John Bowler).
