| 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). |
