867f2ec058 [libpng16] Imported from libpng-1.6.18beta07.tar v1.6.18beta07 2015-06-06 17:03:14 -05:00
Glenn Randers-Pehrson
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.

2dfcf65981 [libpng16] Fixed NO_WRITE_FILTER and -Wconversion build breaks (John Bowler). 2015-06-03 14:58:18 -05:00
John Bowler
b780eba4e4 [libpng16] Fixed cexcept.h in which GCC 5 now reports that one of the auto 
variables in the Try macro needs to be volatile to prevent value
being lost over the setjmp.

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).

Glenn Randers-Pehrson
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.

b66de48b3b [libpng16] Changed png_voidcast(), etc., to voidcast(), etc., in 
contrib/tools/pngfix.c to avoid confusion with the libpng private macros.

Glenn Randers-Pehrson
e6877671f1 [libpng16] Backported filter selection code from libpng-1.7.0beta51, to combine 
sub_row, up_row, avg_row, and paeth_row into try_row and tst_row.

2d069831fb [libpng16] Document PNG_RELEASE_BUILD in the man page. 2015-05-06 20:31:21 -05:00
John Bowler
8ee821e69a [libpng16] PNG_RELEASE_BUILD replaces tests where the code depended on the build base 
type and can be defined on the command line, allowing testing in beta builds. Back
ported from libpng17.

74428df2fd [libpng16] Improved DIV65535 algorithm in simpleover.c. By experiment, 
(x + (x>>16) + 32769) works as well as the previous form and avoids one shift.

d6b1375bf5 [libpng16] Trivial editing of comments in contrib/examples/simpleover.c 2015-05-04 20:25:31 -05:00
John Bowler
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.)

cde3078963 [libpng16] Added contrib/examples/simpleover.c, to demonstrate how to handle

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).

c5370ede95 [libpng16] Reverted "& 0xff" additions of version 1.6.17beta01. Libpng passes 
the Coverity scan without them.
