Version 1.5.7beta01 [November 4, 2011]
|
2011-11-03 05:47:55 +00:00
|
|
|
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.
|
2011-11-04 19:12:04 +00:00
|
|
|
The changes also slightly increase the clarity of the code.

Version 1.5.7beta02 [November 5, 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.
