0ace9f589f [libpng16] PNG_sRGB_PROFILE_CHECKING = (-1) now means no sRGB profile checking. 2014-04-20 20:06:14 -05:00
Glenn Randers-Pehrson
72855fb11e [libpng16] Made progressive reading of interlaced images consistent with the 
behavior of the sequential reader and consistent with the manual. The
row_callback now receives the proper pass number and unexpanded rows,
when png_combine_row is not used or not built, by moving some code
out of the PNG_READ_INTERLACING_SUPPORTED blocks.

Cosmin Truta
82200daec2 [libpng16] $(CP) is now used alongside $(RM_F). Also, use 'copy' instead 
of 'cp' where applicable, and applied other minor makefile changes.
 2014-03-22 09:29:59 -05:00

a518abd582 [libpng16] Removed #if/#else/#endif from inside two pow() calls in pngvalid.c 
because they were handled improperly by Portland Group's PGI-14.1 - PGI-14.3
when using its "__builtin_pow()" function.

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.

e3ae583514 [libpng16] Don't recognize known sRGB profiles as sRGB if they have been hacked. 2014-02-22 22:22:15 -06:00
Glenn Randers-Pehrson
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.
 2014-02-22 21:59:40 -06:00
Glenn Randers-Pehrson
f5df058bee [libpng16] Use a user warning handler in contrib/gregbook/readpng2.c 
instead of the default.
 2014-02-22 07:15:48 -06:00
Glenn Randers-Pehrson
dd6679dce8 [libpng16] Check for __has_extension before using it in pngconf.h, to 
support older Clang versions (Jeremy Sequoia).
 2014-02-20 07:06:59 -06:00
Glenn Randers-Pehrson
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.
 2014-02-17 09:12:52 -06:00
John Bowler
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.

Glenn Randers-Pehrson
103b04170d [libpng16] Moved redefines of png_error(), png_warning(), png_chunk_error(),

Glenn Randers-Pehrson
4ea97d8bc7 [libpng16]Revised png_check_IHDR() to use PNG_SIZE_MAX instead of

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.

1fc0171278 [libpng16] Revised pngvalid.c to support libpng 1.5, which does not support the 
PNG_MAXIMUM_INFLATE_WINDOW option, so #define it out when appropriate in
pngvalid.c
 2013-12-29 15:09:28 -06:00

38f49403bd [libpng16] Update "last changed" dates in recently-patched files. 2013-12-22 15:04:00 -06:00
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. 
This reverts to the previous 'static' implementation and works round
the 'unused static function' warning by using PNG_UNUSED().
 2013-11-22 18:49:58 -06:00
Glenn Randers-Pehrson
503a49458b [libpng16] Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder. 2013-11-22 15:16:04 -06:00
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.

Glenn Randers-Pehrson
bd757acf26 [libpng16] Reverted change of ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED 
to PNG_SET_UNKNOWN_SUPPORTED in pngpread.c; it led to the possibility of
calling png_handle_unknown() twice.
 2013-11-18 18:40:39 -06:00

7976b3c3e3 [libpng16] Moved prototype for png_handle_unknown() in pngpriv.h outside of 
the #ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED/#endif block.
Removed recently-added #ifdef from pngpread.c; moving the prototype
in pngpriv.h fixed the compiler warning that the #ifdef was trying
to solve.

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.

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.

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.
 2013-06-08 13:13:53 -05:00
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.

John Bowler
aa22442a9c [libpng16] Make ARM NEON support work at compile time (not just configure time).

b44cd59ad9 [libpng16] Corrected the test on user transform changes on read. It was in the 
png_set of the transform function, but that doesn't matter unless the
transform function changes the rowbuf size, and that is only valid if
transform_info is called.

43c07e1b48 [libpng16] Fixed incorrect warning of excess deflate data. End condition - the 
warning would be produced if the end of the deflate stream wasn't read
in the last row.  The warning is harmless.

2286a7cef4 [libpng16] Eliminated a warning from the Intel C compiler. The warning is 
technically valid, although a reasonable treatment of division would
show it to be incorrect.

0281dee877 [libpng16] 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 expact 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.

59ae38984f [libpng16] Corrected simplified API default gamma for color-mapped output, added 
a flag to change default. In 1.6.0 when the simplified API was used
to produce color-mapped output from an input image with no gamma
information the gamma assumed for the input could be different from
that assumed for non-color-mapped output.  In particular 16-bit depth
input files were assumed to be sRGB encoded, whereas in the 'direct'
case they were assumed to have linear data.  This was an error.  The
fix makes the simplified API treat all input files the same way and
adds a new flag to the png_image::flags member to allow the
application/user to specify that 16-bit files contain sRGB data
rather than the default linear.
Fixed bugs in the pngpixel and makepng test programs.

f3728100d9 [libpng16] 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.

09a5ca72ac [libpng16] Allow run-time ARM NEON checking to be disabled. A new configure 
option:
    --enable-arm-neon=always will stop the run-time checks. New checks
    within arm/arm_init.c will cause the code not to be compiled unless
    __ARM_NEON__ is set. This should make it fail safe (if someone asks
    for it on then the build will fail if it can't be done.)
Fixed ALIGNED_MEMORY support.

Since all .dfn output is now protected in double quotes unless it is to be macro
substituted the fix should work everywhere.
