Changes since the last public release (1.6.17):
|
|
|
|
Version 1.6.18beta01 [April 1, 2015]
|
|
Removed PNG_SET_CHUNK_[CACHE|MALLOC]_LIMIT_SUPPORTED macros. They
|
|
have been combined with PNG_SET_USER_LIMITS_SUPPORTED (resolves
|
|
bug report by Andrew Church).
|
|
Fixed rgb_to_gray checks and added tRNS checks to pngvalid.c. This
|
|
fixes some arithmetic errors that caused some tests to fail on
|
|
some 32-bit platforms (Bug reports by Peter Breitenlohner [i686]
|
|
and Petr Gajdos [i586]).
|
|
|
|
Version 1.6.18beta02 [April 26, 2015]
|
|
Suppressed some warnings from the Borland C++ 5.5.1/5.82 compiler
|
|
(Bug report by Viktor Szaka'ts).
|
|
|
|
Version 1.6.18beta03 [May 6, 2015]
|
|
Replaced "unexpected" with an integer (0xabadca11) in pngset.c
|
|
where a long was expected, to avoid a compiler warning when PNG_DEBUG > 1.
|
|
Added contrib/examples/simpleover.c, to demonstrate how to handle
|
|
alpha compositing of multiple images, using the "simplified API"
|
|
and an example PNG generation tool, contrib/examples/genpng.c
|
|
(John Bowler).
|
|
|
|
Version 1.6.18beta04 [May 20, 2015]
|
|
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 (John Bowler).
|
|
Avoid Coverity issue 80858 (REVERSE NULL) in pngtest.c
|
|
Avoid a harmless potential integer overflow in png_XYZ_from_xy() (Bug
|
|
report from Christopher Ferris).
|
|
|
|
Version 1.6.18beta05 [May 31, 2015]
|
|
Backport 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.
|
|
Changed png_voidcast(), etc., to voidcast(), etc., in contrib/tools/pngfix.c
|
|
to avoid confusion with the libpng private macros.
|
|
Fixed old cut&paste bug in the weighted filter selection code in
|
|
pngwutil.c, introduced in libpng-0.95, March 1997.
|
|
|
|
Version 1.6.18beta06 [June 1, 2015]
|
|
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.
|
|
|
|
Version 1.6.18beta07 [June 6, 2015]
|
|
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 (because it does nothing and cannot do anything) was apparently
|
|
never tested (John Bowler).
|
|
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 (John Bowler).
|
|
Fixed NO_WRITE_FILTER and -Wconversion build breaks (John Bowler).
|
|
Fix g++ build breaks (John Bowler).
|
|
Quieted some 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.
|
|
Added #ifdef's to contrib/examples programs so people don't try
|
|
to compile them without the minimum required support enabled
|
|
(suggested by Flavio Medeiros).
|
|
|
|
Version 1.6.18beta08 [June 30, 2015]
|
|
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
|
|
be used.
|
|
Removed some unused WEIGHTED_FILTER macros from png.h and pngstruct.h
