| Changes since the last public release (1.5.17): |
| |
| Delay calling png_init_filter_functions() until a row with nonzero filter |
| is found. |
| Changed tabs to 3 spaces in png_debug macros and changed '"%s"m' |
| to '"%s" m' to improve portability among compilers. |
| Added "-Wall" to CFLAGS in contrib/pngminim/*/makefile |
| Conditionally compile some unused functions reported by -Wall in |
| pngminim. |
| Rebuilt configure scripts with automake-1.14.1 and autoconf-2.69 |
| in the tar distributions. |
| Fixed 'unused' warnings and merged with libpng16 pngvalid. |
| Various warnings revealed by configurations added to the tested |
| configurations in libpng 1.6 need corresponding fixes in libpng 1.5. |
| This takes the libpng 1.6 pngvalid.c and adds it back to libpng 1.5, |
| however one write-only test is currently disabled because it does not |
| work; possibly because of failures to reset or initialize the deflate |
| stream correctly in write-only cases. |
| Merged libpng-1.7 changes and created a single pngvalid.c |
| Merged pngvalid and pngtest from libpng-1.5; made compressed chunks |
| after IDAT work with the progressive read code (this is a minor and |
| somewhat ugly fix-up; the proper fix is in 1.6). |
| The 'make all-am' command no longer builds $(check_PROGRAMS), leading |
| to a lack of checks on cross-builds such as ARM. Makefile.am also |
| requires correct dependencies for the check programs on pnglibconf.h |
| otherwise parallel builds on fast machines can sometimes pick up the |
| system pnglibconf.h. |
| Rebuilt configure scripts with automake 1.14.1 and autoconf-2.69. |
| Require automake-1.13 and enable automake "subdirs" feature in autoconf.ac. |
| Allow unversioned links created on install to be disabled in configure. |
| In configure builds 'make install' changes/adds links like png.h |
| and libpng.a to point to the newly installed, versioned, files (e.g. |
| libpng17/png.h and libpng17.a). Three new configure options and some |
| rearrangement of Makefile.am allow creation of these links to be disabled. |
| Removed potentially misleading warning from png_check_IHDR(). |
| Updated scripts/makefile.* to use CPPFLAGS (Cosmin) |
| Quiet an uninitialized memory warning from VC2013 in png_get_png(). |
