pnglibconf.h, allowing more of the decisions to be made internally
(pngpriv.h) during the compile. Without this, symbol prefixing is broken
under certain circumstances on ARM platforms. Now only the API parts of
the optimizations ('check' vs 'api') are exposed in the public header files
except that the new setting PNG_ARM_NEON_OPT documents how libpng makes the
decision about whether or not to use the optimizations.

Libpng 1.6.3beta07 - June 8, 2013

|
Source files with LF line endings (for Unix/Linux) and with a
|
|
"configure" script

Changes since the last public release (1.6.2):
|
|
|
|
Version 1.6.3beta01 [April 25, 2013]
|
|
Revised stack marking in arm/filter_neon.S and configure.ac.
|
|
Ensure that NEON filter stuff is completely disabled when switched 'off'.
|
|
Previously the ARM NEON specific files were still built if the option
|
|
was switched 'off' as opposed to being explicitly disabled.
|
|
|
|
Version 1.6.3beta02 [April 26, 2013]
|
|
Test for 'arm*' not just 'arm' in the host_cpu configure variable.
|
|
Rebuilt the configure scripts.
|
|
|
|
Version 1.6.3beta03 [April 30, 2013]
|
|
Expanded manual paragraph about writing private chunks, particularly
|
|
the need to call png_set_keep_unknown_chunks() when writing them.
|
|
Avoid dereferencing NULL pointer possibly returned from
|
|
png_create_write_struct() (Andrew Church).
|
|
|
|
Version 1.6.3beta05 [May 9, 2013]
|
|
Calculate our own zlib windowBits when decoding rather than trusting the
|
|
CMF bytes in the PNG datastream.
|
|
Added an option to force maximum window size for inflating, which was
|
|
the behavior of libpng15 and earlier.
|
|
Added png-fix-itxt and png-fix-too-far-back to the built programs and
|
|
removed warnings from the source code and timepng that are revealed as
|
|
a result.
|
|
Detect wrong libpng versions linked to png-fix-too-far-back, which currently
|
|
only works with libpng versions that can be made to reliably fail when
|
|
the deflate data contains an out-of-window reference. This means only
|
|
1.6 and later.
|
|
Fixed gnu issues: g++ needs a static_cast, gcc 4.4.7 has a broken warning
|
|
message which it is easier to work round than ignore.
|
|
Updated contrib/pngminus/pnm2png.c (Paul Stewart):
|
|
Check for EOF
|
|
Ignore "#" delimited comments in input file to pnm2png.c.
|
|
Fixed whitespace handling
|
|
Added a call to png_set_packing()
|
|
Initialize dimension values so if sscanf fails at least we have known
|
|
invalid values.
|
|
Attempt to detect configuration issues with png-fix-too-far-back, which
|
|
requires both the correct libpng and the correct zlib to function
|
|
correctly.
|
|
Check ZLIB_VERNUM for mismatches, enclose #error in quotes
|
|
Added information in the documentation about problems with and fixes for
|
|
the bad CRC and bad iTXt chunk situations.
|
|
|
|
Version 1.6.3beta06 [May 12, 2013]
|
|
Allow contrib/pngminus/pnm2png.c to compile without WRITE_INVERT and
|
|
WRITE_PACK supported (writes error message that it can't read P1 or
|
|
Improved png-fix-too-far-back usage message, added --suffix option.
|
|
Revised contrib/pngminim/*/makefile to generate pnglibconf.h with the
|
|
right zlib header files.
|
|
Separated CPPFLAGS and CFLAGS in contrib/pngminim/*/makefile
|
|
|
|
Version 1.6.3beta07 [June 8, 2013]
|
|
Removed a redundant test in png_set_IHDR().
|
|
Added set(CMAKE_CONFIGURATION_TYPES ...) to CMakeLists.txt (Andrew Hundt)
|
|
Deleted set(CMAKE_BUILD_TYPE) block from CMakeLists.txt
|
|
Enclose the prototypes for the simplified write API in
|
|
#ifdef PNG_STDIO_SUPPORTED/#endif
|
|
Make ARM NEON support work at compile time (not just configure time).
|
|
This moves the test on __ARM_NEON__ into pngconf.h to avoid issues when
|
|
using a compiler that compiles for multiple architectures at one time.
|
|
Removed PNG_FILTER_OPTIMIZATIONS and PNG_ARM_NEON_SUPPORTED from
|
|
pnglibconf.h, allowing more of the decisions to be made internally
|
|
(pngpriv.h) during the compile. Without this, symbol prefixing is broken
|
|
under certain circumstances on ARM platforms. Now only the API parts of
|
|
the optimizations ('check' vs 'api') are exposed in the public header files
|
|
except that the new setting PNG_ARM_NEON_OPT documents how libpng makes the
|
|
decision about whether or not to use the optimizations.
