Changes since the last public release (1.5.21):
|
|
|
|
Regenerated configure scripts with libtool-2.4.4
|
|
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.
|
|
Quieted some warnings from Coverity-scan.
|
|
Merged pngtest.c with libpng-1.6.17/pngtest.c
|
|
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
|
|
Removed some comments that the configure script did not handle
|
|
properly from scripts/pnglibconf.dfa and pnglibconf.h.prebuilt.
|
|
Merged png_free_data() with libpng-1.6.17
|
|
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, and pnglibconf.out instead of
|
|
pnglibconf.* in "make clean" (Cosmin).
|
|
Fix incorrect calculation of maximum number of unknown chunks or
|
|
sPLT chunks to be stored (John Bowler).
