| Changes since the last public release (1.6.21): |
| |
| Version 1.6.22beta01 [January 23, 2016] |
| Changed PNG_USE_MKSTEMP to __COVERITY__ to select alternate |
| "tmpfile()" implementation in contrib/libtests/pngstest.c |
| Fixed NO_STDIO build of pngunknown.c to skip calling png_init_io() |
| if there is no stdio.h support. |
| Added a png_image_write_to_memory() API and a number of assist macros |
| to allow an application that uses the simplified API write to bypass |
| stdio and write directly to memory. |
| Added some warnings (png.h) and some check code to detect *possible* |
| overflow in the ROW_STRIDE and simplified image SIZE macros. This |
| disallows image width/height/format that *might* overflow. This is |
| a quiet API change that limits in-memory image size (uncompressed) to |
| less than 4GByte and image row size (stride) to less than 2GByte. |
| Revised workaround for false-positive Coverity issue in pngvalid.c. |
| |
| Version 1.6.22beta02 [February 8, 2016] |
| Only use exit(77) in configure builds. |
| Corrected error in PNG_IMAGE_PNG_SIZE_MAX. This new macro underreported |
| the palette size because it failed to take into account that the memory |
| palette has to be expanded to full RGB when it is written to PNG. |
| Updated CMakeLists.txt, added supporting scripts/gen*.cmake.in |
| and test.cmake.in (Roger Leigh). |
| Relaxed limit checks on gamma values in pngrtran.c. As suggested in |
| the comments gamma values outside the range currently permitted |
| by png_set_alpha_mode are useful for HDR data encoding. These values |
| are already permitted by png_set_gamma so it is reasonable caution to |
| extend the png_set_alpha_mode range as HDR imaging systems are starting |
| to emerge. |
| |
| Version 1.6.22beta03 [February 13, 2016] |
| Added a common-law trademark notice and export control information |
| to the LICENSE file, png.h, and the man page. |
| Restored "& 0xff" in png_save_uint_16() and png_save_uint_32() that |
| were accidentally removed from libpng-1.6.17. |
| Changed PNG_INFO_cHNK and PNG_FREE_cHNK from 0xnnnn to 0xnnnnU in png.h |
| (Robert C. Seacord). |
| Removed dubious "#if INT_MAX" test from png.h that was added to |
| libpng-1.6.19bet02 (John Bowler). |
