f9e37f54eb [libpng16] Worked around rgb-to-gray issues in libpng 1.6. The previous 
attempts to ignore the errors in the code aren't quite enough to
deal with the 'channel selection' encoding added to libpng 1.7; abort.

Glenn Randers-Pehrson
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.
 2015-09-24 22:39:53 -05:00
Glenn Randers-Pehrson
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.

39be3b81da [libpng16] Bump version to 1.6.19beta03 2015-08-19 12:58:26 -05:00
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).

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).

0e9cd91609 [libpng16] Moved config.h.in~ from the "libpng_autotools_files" list to the

e485a09e0e [libpng16] Suppressed some warnings from the Borland C++ 5.5.1/5.82 compiler

f6e7551f06 [libpng16] Eliminated the final two Coverity defects (insecure temporary file 
handling in contrib/libtests/pngstest.c; possible overflow of
unsigned char in contrib/tools/png-fix-itxt.c). To use the "secure"
file handling, define PNG_USE_MKSTEMP, otherwise "tmpfile()" will
continue to be used.

b26b51d154 [libpng16] Quieted Coverity issues in pngfix.c, png-fix-itxt.c, pngvalid.c, 
pngstest.c, and pngimage.c. Most seem harmless, but png-fix-itxt
would only work with iTXt chunks with length 255 or less.

25bfb13770 [libpng16] Removed non-working progressive reader 'skip' function. This 
function has apparently never been used. It was implemented
to support back-door modification of png_struct in libpng-1.4.x
but was apparently never tested (because it does nothing and cannot
do anything).

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.

0f12df19a1 [libpng16] Added PNG generation tool, fixed unitialized pointer in 
simpleover. Also added a comment to png.h pointing out that the pointer must
 be set to NULL!  (simpleover crashes with any slightly complex command lines
 without this fix.)
 2015-05-04 19:58:41 -05:00

6eecfe3886 [libpng16] Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha 
value was wrong.  It's not clear if this affected the final stored
value; in the obvious code path the upper and lower 8-bits of the
alpha value were identical and the alpha was truncated to 8-bits
rather than dividing by 257 (John Bowler).

John Bowler
03df189954 [libpng16] Fixed array size calculations to avoid warnings. At various points 
in the code the number of elements in an array is calculated using
sizeof.  This generates a compile time constant of type (size_t) which
is then typically assigned to an (unsigned int) or (int). Some versions
of GCC on 64-bit systems warn about the apparent narrowing, even though
the same compiler does apparently generate the correct, in-range,
numeric constant.  This adds appropriate, safe, casts to make the
warnings go away.
