45625eceb4 [libpng16] Don't recognize known sRGB profiles as sRGB if they have been hacked, 
but don't reject them and don't issue a copyright violation warning.
Simplified code in pngrutil.c that decides whether to warn about an
incorrect ancillary PLTE chunk.

eb657ae68f [libpng16] Added png_ptr->process_mode = PNG_READ_IDAT_MODE in 
png_push_read_chunk after recognizing the IDAT chunk, which avoids an
infinite loop while reading a datastream whose first IDAT chunk is of
zero-length.

dd6679dce8 [libpng16] Check for __has_extension before using it in pngconf.h, to 
support older Clang versions (Jeremy Sequoia).

9c5a1baea5 [libpng16] Check for info_ptr == NULL early in png_read_end() so we don't need 
to run all the png_handle_*() and depend on them to return if info_ptr == NULL.
This improves the performance of png_read_end(png_ptr, NULL) and makes
it more robust against future programming errors.

dba54b8888 [libpng16] Moved OS dependent code from arm/arm_init.c, to allow the included 
implementation of the ARM NEON discovery function to be set at
build-time and provide sample implementations from the current code in the
contrib/arm-neon subdirectory. The __linux__ code has also been changed to
compile and link on Android by using /proc/cpuinfo, and the old linux code
is in contrib/arm-neon/linux-auxv.c.  The new code avoids POSIX and Linux
dependencies apart from opening /proc/cpuinfo and is C90 compliant.

103b04170d [libpng16] Moved redefines of png_error(), png_warning(), png_chunk_error(),

d0479d24a0 [libpng16] Allow unversioned links created on install to be disabled in 
configure.  In configure builds 'make install' changes/adds links like png.h
and libpng.a to point to the newly installed, versioned, files (e.g.
libpng17/png.h and libpng17.a). Three new configure options and some
rearrangement of Makefile.am allow creation of these links to be disabled.

John Bowler
8f1150eb75 [libpng16] Made transform implementation functions static. This makes the 
internal functions called by png_do_{read|write}_transformations static. On an
x86-64 DLL build (Gentoo Linux) this reduces the size of the text
segment of the DLL by 1208 bytes, about 0.6%. It also simplifies
maintenance by removing the declarations from pngpriv.h and allowing
easier changes to the internal interfaces.
 2013-12-19 15:33:49 -06:00
John Bowler
c10930a4fc [libpng16] Bookkeeping: Moved functions around (no changes). Moved transform 
function definitions before the place where they are called so that
they can be masde static. Move the intrapixel functions and the
grayscale palette builder out of the png?tran.c files. The latter
isn't a transform function and is no longer used internally, and the
former MNG specific functions are better placed in pngread/pngwrite.c

0f6303301f [libpng16] Fixed pngvalid 'fail' function declaration on the Intel C Compiler.

Glenn Randers-Pehrson
c912050a7b [libpng16] Fixed 'minimal' builds. Various obviously useful minimal 
configurations don't build because of missing contrib/libtests test programs
and overly complex dependencies in scripts/pnglibconf.dfa. This change adds
contrib/conftest/*.dfa files that can be used in automatic build
scripts to ensure that these configurations continue to build.

Removed recently-added #ifdef from pngpread.c; moving the prototype
in pngpriv.h fixed the compiler warning that the #ifdef was trying

fd8bba4b80 [libpng16] Changed NEON implementation selection mechanism to allow assembler 
or intrinsics to be turned on during the build by defining
PNG_ARM_NEON_IMPLEMENTATION to the correct value (2 or 1).  The
default is "undefined" and the build type is selected in pngpriv.h.

34ac3691cb [libpng16] Make autogen.sh work with automake 1.13 as well as 1.14. Do this 
by always removing the 1.14 'compile' script but never checking for it.
 2013-10-06 11:29:55 -05:00
John Bowler
236e105170 [libpng16] Simplified error message code in pngunknown. The simplification has 
the useful side effect of avoiding a bogus warning generated by the latest
version of the Intel C compiler (it objects to
condition ? string-literal : string-literal).
 2013-10-04 20:28:33 -05:00
John Bowler
5b1df53a82 [libpng16] Cleaned up (char*) casts of zlib messages. The latest version of 
the Intel C compiler complains about casting a string literal as (char*), so
copied the treatment of z_const from the library code into pngfix.c
 2013-10-04 20:13:17 -05:00
John Bowler
940b37b197 [libpng16] Made changes for compatibility with automake 1.14: 
1) Added the 'compile' program to the list of programs that must be cleaned
       in autogen.sh
    2) Added 'subdir-objects' which causes .c files in sub-directories to be
       compiled such that the corresponding .o files are also in the
       sub-directory.  This is because automake 1.14 warns that the
       current behavior of compiling to the top level directory may be removed
       in the future.
    3) Updated dependencies on pnglibconf.h to match the new .o locations and
       added all the files in contrib/libtests and contrib/tools that depend
       on pnglibconf.h
    4) Added 'BUILD_SOURCES = pnglibconf.h'; this is the automake recommended
       way of handling the dependencies of sources that are machine generated;
       unfortunately it only works if the user does 'make all' or 'make check',
       so the dependencies (3) are still required.

de723276e5 [libpng16] Bump version to 1.6.7beta02 2013-10-02 13:47:02 -05:00
John Bowler
8f381901e3 [libpng16] Avoid up-cast warnings in pngvalid.c. On ARM the alignment 
requirements of png_modifier are greater than that of png_store and as a
consequence compilation of pngvalid.c results in a warning about increased
alignment requirements because of the bare cast to (png_modifier*). The code
is safe, because the pointer is known to point to a stack allocated
png_modifier, but this change avoids the warning.

  Fixed default behavior of ARM_NEON_API. If the ARM NEON API option was
    compiled without the CHECK option it defaulted to on, not off.

  Check user callback behavior in pngunknown.c. Previous versions compiled
    if SAVE_UNKNOWN was not available but did nothing since the callback
    was never implemented.

  Merged pngunknown.c with 1.7 version and back ported 1.7 improvements/fixes
 2013-09-30 11:24:17 -05:00
John Bowler
15a80443de [libpng16] Allow HANDLE_AS_UNKNOWN to work when other options are configured 
off. Also fixed the pngminim makefiles to work when $(MAKEFLAGS) contains stuff
which terminates the make options (as by default in recent versions of Gentoo).
 2013-09-21 10:06:32 -05:00
Glenn Randers-Pehrson
6f8f004fe1 [libpng16] Added #ifdef PNG_READ_SUPPORTED/endif around the

John Bowler
f5f1206778 [libpng16] Fixed undefined behavior in contrib/tools/pngfix.c and added new 
strip option. pngfix relied on undefined behavior and even a simple change from
gcc to g++ caused it to fail.  The new strip option 'unsafe' has been
implemented and is the default if --max is given.  Option names have
been clarified, with --strip=transform now stripping the bKGD chunk,
which was stripped previously with --strip=unused.
Added all documented chunk types to pngpriv.h

f260f6d156 [libpng16] Protect symbol prefixing against CC/CPPFLAGS/CFLAGS useage. 
Previous iOS/Xcode fixes for the ARM NEON optimizations moved the test
on __ARM_NEON__ from configure time to compile time.  This breaks symbol
prefixing because the definition of the special png_init_filter_functions
call was hidden at configure time if the relevant compiler arguments are
passed in CFLAGS as opposed to CC.  This change attempts to avoid all
the confusion that would result by declaring the init function even when
it is not used, so that it will always get prefixed.

John Bowler
18dd07e3e6 [libpng16] 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.

aa22442a9c [libpng16] 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

294d0b8408 [libpng16] Detect wrong libpng versions linked to pngdeflate, 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.

fixitxt when the chunk length is more than 65535 (untested, no test case).
