Added support for ARM processor, when decoding all PNG up-filtered rows

and any other-filtered rows with 3 or 4 bytes per pixel (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

Removed an obsolete line from the manual.

===========================================================================
|
||||
NOTICE November 17, 2012:
|
||||
The location of the git repository at SourceForge has changed.
|
||||
Visit http://libpng.sf.net/ for details.
|
||||
===========================================================================
|
||||
Version 1.5.15beta01 [February 4, 2013]
|
||||
Enabled renaming of the extern (but not DLL exported) ARM filter functions.
|
||||
Also enabled inclusion of pngpriv.h in non-C files by preventing C/C++
|
||||
specific definitions if PNG_VERSION_INFO_ONLY is defined.
|
||||
Added png_get_palette_max() function.
|
||||
|
||||
Version 1.5.15beta02 [February 5, 2013]
|
||||
Made a probably general fix for the preprocessing used to generate source
|
||||
files. This change might make the check for a special C preprocessor
|
||||
unnecessary, and it also eliminates the requirement for sed in the
|
||||
configure build process.
|
||||
Fix typo in Makefile.am, fix scripts/pnglibconf.mak and makefile.std
|
||||
Rebuilt Makefile.in, configure, etc., with autoconf-2.69 and automake-1.13
|
||||
Fix 'setting' handling in options.awk and fixed palette_max API
|
||||
|
||||
Version 1.5.15beta03 [February 7, 2013]
|
||||
Remove SUN OS cc -E workround - no longer required
|
||||
Turn serial tests back on (recently turned off by autotools upgrade).
|
||||
|
||||
Version 1.5.15beta04 [February 15, 2013]
|
||||
Enclosed the new png_get_palette_max in #ifdef PNG_GET_PALETTE_MAX_SUPPORTED
|
||||
block, and revised pnglibconf.h and pnglibconf.h.prebuilt accordingly.
|
||||
|
||||
Version 1.5.15beta05 [February 17, 2013]
|
||||
Use approved/supported Android method to check for NEON, use Linux/POSIX
|
||||
1003.1 API to check /proc/self/auxv avoiding buffer allocation and other
|
||||
library calls.
|
||||
Fixed a race condition in the creation of the build 'scripts' directory
|
||||
while building with a parallel make.
|
||||
Use parentheses more consistently in "#if defined(MACRO)" tests.
|
||||
|
||||
Version 1.5.15beta06 [February 22, 2013]
|
||||
Fixed PNG_ALIGN(ED)_MEMORY and add ability to turn off ARM_NEON
|
||||
runtime checks
|
||||
Updated the INSTALL document.
|
||||
|
||||
Version 1.5.15beta07 [February 27, 2013]
|
||||
Revised INSTALL to recommend using CPPFLAGS instead of INCLUDES.
|
||||
Revised scripts/makefile.freebsd to respect ZLIBLIB and ZLIBINC.
|
||||
Revised scripts/dfn.awk to work with the buggy MSYS awk that has trouble
|
||||
with CRLF line endings.
|
||||
|
||||
Version 1.5.15beta08 [March 5, 2013]
|
||||
Avoid a possible memory leak in contrib/gregbook/readpng.c
|
||||
Made the _SUPPORTED macro definitions consistent. The change made in
|
||||
libpng15 to #define *_SUPPORTED 1, to match the use of -D*_SUPPORTED
|
||||
(which means -D*_SUPPORTED=1) and avoid compiler warnings from GCC was made
|
||||
inconsistently and causes problems as a result, also some additions in
|
||||
pnglibconf.h.prebuilt were inconsistent (omitting the 1). This changes 1.5
|
||||
back to the scheme used both before (1.4) and after (1.6). This might cause
|
||||
some build scripts to issue warnings, and might, in the extreme, cause some
|
||||
applications to fail (but they would fail anyway against 1.6). It seems
|
||||
safer to go for consistency, given the change in 1.6, not correctness here,
|
||||
particularly as 'make check' currently warns anyway on the symbols.dfn check
|
||||
because of the inconsistencies.
|
||||
Corrected Android builds and corrected libpng.vers with symbol
|
||||
prefixing This adds an API to set optimization options externally,
|
||||
providing an alternative and general solution for the non-portable
|
||||
run-time tests used by the ARM Neon code. It also makes those tests
|
||||
compile and link on Android.
|
||||
The order of settings vs options in pnglibconf.h is reversed to allow
|
||||
settings to depend on options and options can now set (or override) the
|
||||
defaults for settings.
|
||||
|
||||
Version 1.5.15beta09 [March 13, 2013]
|
||||
Fixed CMakelists.txt to allow building a single variant of the library
|
||||
(Claudio Bley):
|
||||
Introduced a PNG_LIB_TARGETS variable that lists all activated library
|
||||
targets. It is an error if this variable ends up empty, ie. you have
|
||||
to build at least one library variant.
|
||||
Made the *_COPY targets only depend on library targets actually being build.
|
||||
Use PNG_LIB_TARGETS to unify a code path.
|
||||
Changed the CREATE_SYMLINK macro to expect the full path to a file as the
|
||||
first argument. When symlinking the filename component of that path is
|
||||
determined and used as the link target.
|
||||
Use copy_if_different in the CREATE_SYMLINK macro.
|
||||
Eliminated two warnings from the Intel C compiler. The warnings are
|
||||
technically valid, although a reasonable treatment of division would
|
||||
show it to be incorrect.

*******************************************************************************
|

|

* Support for arbitrary implementation-specific optimizations. The API allows
|

* particular options to be turned on or off. 'Option' is the number of the

* by the PNG_OPTION_ defines below.
|

|

* HARDWARE: normally hardware capabilites, such as the Intel SSE instructions,
|
||||
* are detected at run time, however sometimes it may be impossible
|
||||
* to do this in user mode, in which case it is necessary to discover
|
||||
* the capabilities in an OS specific way. Such capabilities are
|
||||
* listed here when libpng has support for them and must be turned
|
||||
* ON by the application if present.
|
||||
*
|
||||
* SOFTWARE: sometimes software optimizations actually result in performance
|
||||
* decrease on some architectures or systems, or with some sets of
|
||||
* PNG images. 'Software' options allow such optimizations to be
|

* selected at run time.
