|
||||
Changes since the last public release (1.5.7):
|
||||
|
||||
Version 1.5.7beta01 [November 4, 2011]
|
||||
Added support for ARM processor (Mans Rullgard)
|
||||
Fixed bug in pngvalid on early allocation failure; fixed type cast in
|
||||
pngmem.c; pngvalid would attempt to call png_error() if the allocation
|
||||
of a png_struct or png_info failed. This would probably have led to a
|
||||
crash. The pngmem.c implementation of png_malloc() included a cast
|
||||
to png_size_t which would fail on large allocations on 16-bit systems.
|
||||
Fix for the preprocessor of the Intel C compiler. The preprocessor
|
||||
splits adjacent @ signs with a space; this changes the concatentation
|
||||
token from @-@-@ to PNG_JOIN; that should work with all compiler
|
||||
preprocessors.
|
||||
Paeth filter speed improvements from work by Siarhei Siamashka. This
|
||||
changes the 'Paeth' reconstruction function to improve the GCC code
|
||||
generation on x86. The changes are only part of the suggested ones;
|
||||
just the changes that definitely improve speed and remain simple.
|
||||
The changes also slightly increase the clarity of the code.
|
||||
|
||||
Version 1.5.7beta02 [November 11, 2011]
|
||||
Check compression_type parameter in png_get_iCCP and remove spurious
|
||||
casts. The compression_type parameter is always assigned to, so must
|
||||
be non-NULL. The cast of the profile length potentially truncated the
|
||||
value unnecessarily on a 16-bit int system, so the cast of the (byte)
|
||||
compression type to (int) is specified by ANSI-C anyway.
|
||||
Fixed FP division by zero in pngvalid.c; the 'test_pixel' code left
|
||||
the sBIT fields in the test pixel as 0, which resulted in a floating
|
||||
point division by zero which was irrelevant but causes systems where
|
||||
FP exceptions cause a crash. Added code to pngvalid to turn on FP
|
||||
exceptions if the appropriate glibc support is there to ensure this is
|
||||
tested in the future.
|
||||
Updated scripts/pnglibconf.mak and scripts/makefile.std to handle the
|
||||
new PNG_JOIN macro.
|
||||
Added versioning to pnglibconf.h comments.
|
||||
Simplified read/write API initial version; basic read/write tested on
|
||||
a variety of images, limited documentation (in the header file.)
|
||||
Installed more accurate linear to sRGB conversion tables. The slightly
|
||||
modified tables reduce the number of 16-bit values that
|
||||
convert to an off-by-one 8-bit value. The "makesRGB.c" code that was used
|
||||
to generate the tables is now in a contrib/sRGBtables sub-directory.
|
||||
|
||||
Version 1.5.7beta03 [November 17, 2011]
|
||||
Removed PNG_CONST from the sRGB table declarations in pngpriv.h and png.c
|
||||
Added run-time detection of NEON support.
|
||||
Added contrib/libtests; includes simplified API test and timing test and
|
||||
a color conversion utility for rapid checking of failed 'pngstest' results.
|
||||
Multiple transform bug fixes plus a work-round for double gamma correction.
|
||||
libpng does not support more than one transform that requires linear data
|
||||
at once - if this is tried typically the results is double gamma
|
||||
correction. Since the simplified APIs can need rgb to gray combined with
|
||||
a compose operation it is necessary to do one of these outside the main
|
||||
libpng transform code. This check-in also contains fixes to various bugs
|
||||
in the simplified APIs themselves and to some bugs in compose and rgb to
|
||||
gray (on palette) itself.
|
||||
Fixes for C++ compilation using g++ When libpng source is compiled
|
||||
using g++. The compiler imposes C++ rules on the C source; thus it
|
||||
is desireable to make the source work with either C or C++ rules
|
||||
without throwing away useful error information. This change adds
|
||||
png_voidcast to allow C semantic (void*) cases or the corresponding
|
||||
C++ static_cast operation, as appropriate.
|
||||
Added --noexecstack to assembler file compilation. GCC does not set
|
||||
this on assembler compilation, even though it does on C compilation.
|
||||
This creates security issues if assembler code is enabled; the
|
||||
work-around is to set it by default in the flags for $(CCAS)
|
||||
Work around compilers that don't support declaration of const data. Some
|
||||
compilers fault 'extern const' data declarations (because the data is
|
||||
not initialized); this turns on const-ness only for compilers where
|
||||
this is known to work.
|
||||
|
||||
Version 1.5.7beta04 [November 17, 2011]
|
||||
Since the gcc driver does not recognize the --noexecstack flag, we must
|
||||
use the -Wa prefix to have it passed through to the assembler.
|
||||
Also removed a duplicate setting of this flag.
|
||||
Added files that were omitted from the libpng-1.5.7beta03 zip distribution.
|
||||
|
||||
Version 1.5.7beta05 [(PENDING RELEASE)]
|
||||
Removed "zTXt" from warning in generic chunk decompression function.
|
||||
Validate time settings passed to pngset() and png_convert_to_rfc1123()
|
||||
(Frank Busse).
|
||||
Allow row_stride==0 to indicate default stride in simplified API.
|
||||
Added MINGW support to CMakeLists.txt
|
||||
Reject invalid compression flag or method when reading the iTXt chunk.

Backed out 'simplified' API changes. The API seems too complex and there
