| Changes since the last public release (1.6.8): |
| Bookkeeping: Moved functions around (no changes). Moved transform |
| function definitions before the place where they are called so that |
| they can be masde static. Move the intrapixel functions and the |
| grayscale palette builder out of the png?tran.c files. The latter |
| isn't a transform function and is no longer used internally, and the |
| former MNG specific functions are better placed in pngread/pngwrite.c |
| Made transform implementation functions static. This makes the internal |
| functions called by png_do_{read|write}_transformations static. On an |
| x86-64 DLL build (Gentoo Linux) this reduces the size of the text |
| segment of the DLL by 1208 bytes, about 0.6%. It also simplifies |
| maintenance by removing the declarations from pngpriv.h and allowing |
| easier changes to the internal interfaces. |
| Rebuilt configure scripts with automake-1.14.1 and autoconf-2.69 |
| in the tar distributions. |
| Added checks for libpng 1.5 to pngvalid.c. This supports the use of |
| this version of pngvalid in libpng 1.5 |
| Merged with pngvalid.c from libpng-1.7 changes to create a single |
| pngvalid.c |
| Removed #error macro from contrib/tools/pngfix.c (Thomas Klausner). |
| Merged pngrio.c, pngtrans.c, pngwio.c, and pngerror.c with libpng-1.7.0 |
| Merged libpng-1.7.0 changes to make no-interlace configurations work |
| with test programs. |
| Revised pngvalid.c to support libpng 1.5, which does not support the |
| PNG_MAXIMUM_INFLATE_WINDOW option, so #define it out when appropriate in |
| pngvalid.c |
| 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). |
| Added clang attribute support (Cosmin). |
| Quiet an uninitialized memory warning from VC2013 in png_get_png(). |
