134c5761fa [libpng16] Fix new leak when text compression is disabled. 2012-08-10 10:49:21 -05:00

865e14fd32 [libpng16] Revised comments about info_ptr->signature, added CHANGES entry. 2012-08-10 08:05:53 -05:00

5d1df4fdf4 [libpng16] Removed png_get_signature() and info_ptr->signature from WRITE-only 
builds.  Restored png_get_channels() to WRITE-only builds.

8d3453a22d [libpng16] Insist on autotools 1.12.1 for git builds because there are security 
issues with 1.12 and insisting on anything less would allow 1.12 to be used.

4430b91363 [libpng16] Restore info_ptr members that were deleted by the previous 
patch; they are needed by png_set_IHDR() for both read and write.  Fix
some ifdefs that caused the contrib/pngminim/ applications to not compile.

dff6f4c4f0 [libpng16Cleanup of png_set_filler(). This function does very different things 
on read and write.  In libpng 1.6 the two cases can be distinguished and
considerable code cleanup, and extra error checking, is possible.  This
makes calls on the write side that have no effect be ignored with a
png_app_error(), which can be disabled in the app using
png_set_benign_errors(), and removes the spurious use of usr_channels
on the read side.

432c174b64 [libpng16] Eliminated use of png_sizeof(); use sizeof() instead, and use. 
a consistent style for (sizeof type) and (sizeof (array))

5f5977e708 [libpng16] Re-eliminated the use of strcpy() in pngtest.c. An unncessary use 
of strcpy() was accidentally re-introduced in libpng16; this change replaces
it with strncpy().

0a9f8eb272 [libpng16] Fixed configurations where floating point is completely disabled. 
Because of the changes to support symbol prefixing PNG_INTERNAL_FUNCTION
declares floating point APIs during libpng builds even if they are completely
disabled. This requires the png floating point types (png_double*) to be
declared even though the functions are never actually defined.  This
change provides a dummy definition so that the declarations work, yet any
implementation will fail to compile because of an incomplete type.

cad0150d12 [libpng16] Corrected handling of row_pointers in example.c and added some 
comments.  It has apparently been wrong since libpng-1.0.1c (confusing
use of a 1D and a 2D array for the image source).

ee427ad39a [libpng16] Add information about png_calloc() to the manual. 2012-08-03 08:39:54 -05:00

01b813000a [libpng16] Removed references to png_zalloc() and png_zfree() from the manual. 
They have not been exported to applications since libpng12.

449db5a9c1 [libpng16] Check for existence of __GNUC_MINOR__ before testing its value 
(This is probably unnecessary because it's inside a __GNUC__ block.)

80b67e47e8 [libpng16] Added default blank "#define PNG_RESTRICT" to pngconf.h 
This has been missing since the feature was introduced in libpng-1.6.0beta04.

5845d3eabd [libpng16] Removed scripts/makefile.cegcc from the *.zip and *.7z 
distributions; it depends on configure, which is not included in those
archives.

96b917056d [libpng16] Revised png_set_keep_unknown_chunks() so num_chunks < 0 means 
ignore all unknown chunks and all known chunks except for IHDR, PLTE, tRNS,
IDAT, and IEND.  Previously it only meant ignore all unknown chunks, the
same as num_chunks == 0. Revised png_image_skip_unused_chunks() to
provide a list of chunks to be processed instead of a list of chunks to
ignore.  Revised contrib/gregbook/readpng2.c accordingly.

14ca47b453 [libpng16] Improved performance of new do_check_palette_indexes() function

the check is wanted out of the function.

b1e7771d5e [libpng16] Do not depend upon a GCC feature macro being available for use in 
generating the linker mapfile symbol prefix.

ff7b7ba060 [libpng16] Made fixes for new optimization warnings from gcc 4.7.0. 
The compiler performs an optimization which is safe; however it then warns
about it.  Changing the type of 'palette_number' in pngvalid.c removes the
warning.

John Bowler
b45416921b [libpng16] Removed need for -Wno-cast-align with clang. clang correctly warns 
on alignment increasing pointer casts when -Wcast-align is passed. This
fixes the cases clang warns about either (pngread.c) by eliminating the
casts from png_bytep to png_uint_16p or, for pngrutil.c where the cast
is previously verified or pngstest.c where it is OK by introducing new
png_aligncast macros to do the cast in a way that clang accepts.

missing RELEASE variable (Toby Thain).
