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().
