571abc9a67 [libpng16] Update CHANGES and ANNOUNCE, fix typos in png.h comments 2016-01-18 12:55:51 -06:00
John Bowler
175a126a1a Simplified API: write-to-memory, overflow handling 
This implements an API and provides a number of assist macros to allow an
application which uses the simplified API write to bypass stdio and write
directly to memory.

It also includes 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.  A quiet API change that limits
in-memory image size (uncompressed) to less that 4GByte and image row size
(stride) to less than 2GByte.

01a0e8062d [libpng16] Reverted addition of png_set_filler_16 and png_set_add_alpha_16() 
functions. They unnecessarily duplicate png_set_filler() and png_set_add_alpha()
which now work properly with 16-bit images.

efe4e5d10d [libpng16] Reverted the fix of byte order in png_do_read_filler() with 16-bit 
input that was made in version 1.6.17beta01, to preserve legacy
behavior even though it was incorrect.  Instead, added new API
png_set_filter_16() and png_set_add_alpha_16() that set a flag to
make png_do_read_filter() interpret the filler bytes properly.

John Bowler
2d62f7406f [libpng16] Fixed the recently reported 1's complement security issue by 
replacing the value that is illegal in the PNG spec, in both signed and
unsigned values, with 0. Illegal unsigned values (anything greater than or equal
to  0x80000000) can still pass through, but since these are not illegal
in ANSI-C (unlike 0x80000000 in the signed case) the checking that
occurs later can catch them (John Bowler).

751cee5ef1 [libpng16] Added signed/unsigned 16-bit safety net. This removes the dubious 
0x8000 flag definitions on 16-bit systems. They aren't supported
yet the defs *probably* work, however it seems much safer to do this
and be advised if anyone, contrary to advice, is building libpng 1.6
on a 16-bit system. It also adds back various switch default clauses
for GCC; GCC errors out if they are not present (with an appropriately
high level of warnings).

89edbf8317 [libpng16] Removed WRITE_WEIGHTED_FILTERED code, to save a few kbytes of the 
compiled library size. It never worked properly and as far as we can
tell, no one uses it. The png_set_filter_heuristics() and
png_set_filter_heuristics_fixed() APIs are retained but deprecated
and do nothing.
