3167541570 [libpng16] Fixed 'prefix' builds on clean systems. The generation of pngprefix.h 
should not require itself.

42369ccd85 [libpng16] Added symbol prefixing that allows all the libpng external symbols 
to be prefixed (suggested by Reuben Hawkins).  This is work in progress that
breaks some non-configure builds.

572b078d8c [libpng16] Cleaned up pngpriv.h to consistently declare all functions and data. 
Also eliminated PNG_CONST_DATA, which is apparently not needed but we
can't be sure until it is gone.

40ca77a721 [libpng16] Improved pngstest speed by not doing redundant tests and add const 
to the background parameter of png_image_finish_read. The --background
option is now done automagically only when required, so that commandline
option no longer exists.

1eb2c48458 [libpng16] Updated configure.ac from autoupdate: added --enable-werror option. 
Also some layout regularization and removal of introduced tab characters
(replaced with 3-character indentation).  Obsolete macros identified by
autoupdate have been removed; the replacements are all in 2.59 so
the pre-req hasn't been changed.  --enable-werror checks for support
for -Werror (or the given argument) in the compiler.  This mimics the
gcc configure option by allowing -Werror to be turned on safely; without
the option the tests written in configure itself fail compilation because
they cause compiler warnings.

8fb6c6a9b3 [libpng16] Eliminated Intel icc/icl compiler warnings. The Intel (GCC derived) 
compiler issues slightly different warnings from those issued by the
current vesions of GCC. This eliminates those warnings by
adding/removing casts and small code rewrites.

when png_uint_32 and unsigned long are of different sizes.

fcd301daed [libpng16] Changed png_memcpy to C assignment where appropriate. Changed all 
those uses of png_memcpy that were doing a simple assignment to assignments
(all those cases where the thing being copied is a non-array C L-value.)
Added some error checking to png_set_*() routines and removed the
reference to the non-exported function png_memcpy() from example.c. Fixed
the Visual C 64-bit build - it requires jmp_buf to be aligned, but it had
become misaligned.

5d56786eff [libpng16] Implemented 'restrict' for png_info and png_struct. 
Added new "png_structrp" typedef. Because of the
way libpng works both png_info and png_struct are always accessed via a
single pointer.  This means adding C99 'restrict' to the pointer gives
the compiler some opportunity to optimize the code.  This change allows that.

29fca0d497 [libpng16] Enabled png_get_sCAL_fixed() if floating point APIs are enabled. 
Previously it was disabled whenever internal fixed point arithmetic was
selected, which meant it didn't exist even on systems where FP was available
but not preferred.

df477e4652 [libpng16] Eliminated png_info_destroy. It is now used only in png.c 
and only calls one other internal function and memset.

d332c67da7 [libpng16] Start-up code size improvements, error handler flexibility. 
These changes alter how the tricky allocation of the initial png_struct and
png_info structures are handled. png_info is now handled in pretty much the
same way as everything else, except that the allocations handle NULL return
silently.  png_struct is changed in a similar way on allocation and on
deallocation a 'safety' error handler is put in place (which should never
be required).  The error handler itself is changed to permit mismatches
in the application and libpng error buffer size; however, this means a
silent change to the API to return the jmp_buf if the size doesn't match
the size from the libpng compilation; libpng now allocates the memory and
this may fail.  Overall these changes result in slight code size
reductions; however, this is a reduction in code that is always executed
so is particularly valuable.  Overall on a 64-bit system the libpng DLL
decreases in code size by 1733 bytes.  pngerror.o increases in size by
about 465 bytes because of the new functionality.

efaeadaa86 [libpng16] Added pngconfig.h file. This indirect reference to config.h avoids 
problems with build scripts that search for config.h and find an
inappropriate one in the standard paths.

eb26ee6602 [libpng16] Fixed race conditions in parallel make builds. With higher degrees 
of parallelism during 'make' the use of the same temporary file names such
as 'dfn*' can result in a race where a temporary file from one arm of the
build is deleted or overwritten in another arm.  This changes the
temporary files for suffix rules to always use $* and ensures that the
non-suffix rules use unique file names.

17878c6e65 [libpng15] Work around compilers that don't support declaration of const data. 
Some compilers fault 'extern const' data declarations (because the data is
not initialized); this turns on const-ness only for compilers where
this is known to work.

John Bowler
4fa96a42f7 [libpng15] Fixes for C++ compilation using g++ When libpng source is compiled 
using g++. The compiler imposes C++ rules on the C source; thus it
    is desireable to make the source work with either C or C++ rules
    without throwing away useful error information.  This change adds
    png_voidcast to allow C semantic (void*) cases or the corresponding
    C++ static_cast operation, as appropriate.

a004e23a4c [libpng15] Fixed FP division by zero in pngvalid.c; the 'test_pixel' code left 
the sBIT fields in the test pixel as 0, which resulted in a floating
point division by zero which was irrelevant but causes systems where
FP exceptions cause a crash. Added code to pngvalid to turn on FP
exceptions if the appropriate glibc support is there to ensure this is
tested in the future.

88bcdc269b [libpng] 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.

aff44028ba [libpng15] 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.

92ef313c77 [libpng15] Fixed compiler warnings with Intel and MSYS compilers. 
The logical shift fix for Microsoft Visual C is required by other compilers,
so this enables that fix for all compilers when using compile-time constants.
Under MSYS 'byte' is a name declared in a system header file, so we
changed the name of a local variable to avoid the warnings that result.

John Bowler
fb5b3ac013 [libpng15] Prevent libpng overwriting unused bits at the end of the image when 
is not byte aligned, while reading. Prior to libpng-1.5.6 libpng would
overwrite the end of the image if the row width is not an exact multiple
of 8 bits and the image is not interlaced.

57cbcf6b8f [libpng15] Add ability to call png_read_update_info multiple times to pngvalid.c 2011-10-14 19:43:53 -05:00
John Bowler
07772cba07 [libpng15] Fixes for multiple calls to png_read_update_info. 
These fixes attend to most of the errors revealed in pngvalid, however doing
the gamma work twice results in inaccuracies that can't be easily fixed.
There is now a warning in the code if this is going to happen.

d58251b47e [libpng15] Reverted previous change; removed png_get_compression_buffer() API. 
It is too risky. Exactly how png_ptr->zbuf is used is under control of the
individual chunk implementation and there could easily be significant changes
within a major release.

John Bowler
8be28e3eb6 [libpng15] Optimized png_combine_row() when rows are aligned This gains a 
small percentage for 16-bit and 32-bit pixels in the typical case where the
output row buffers are appropriately aligned. The optimization was not
previously possible because the png_struct buffer was always misaligned.
 2011-10-07 18:36:37 -05:00
John Bowler
ac8375d000 [libpng15] Align png_struct::row_buf - previously it was always unaligned, 
caused by a bug in the code that attempted to align it; the code needs to
subtract one from the pointer to take account of the filter byte prepended to
each row.
 2011-10-06 22:27:16 -05:00
Glenn Randers-Pehrson
65c0339b5c [libpng15] Speed up png_combine_row() for interlaced images. This reduces the 
generality of the code, allowing it to be optimized for Adam7 interlace.  The
masks passed to png_combine_row() are now generated internally, avoiding
some code duplication and localizing the interlace handling somewhat.

John Bowler
f3f7e14727 [libpng15] Fixed 64-bit compilation errors (gcc). The errors fixed relate 
to conditions where types that are 32 bits in the GCC 32-bit
world (uLong and png_size_t) become 64 bits in the 64-bit
world.  This produces potential truncation errors which the
compiler correctly flags.

cd3b0cc4d9 [devel] Fixed a problem in png_do_expand_palette() exposed by optimization in 
1.5.3beta06
  Also removed a spurious (totally unused and confusing) member from png_info.
  The palette expand optimization prevented expansion to an intermediate RGBA
    form if tRNS was present but alpha was marked to be stripped; this exposed
    a check for tRNS in png_do_expand_palette() which is inconsistent with the
    code elsewhere in libpng.

59a6c379dd [devel] Revised pngvalid.c to test PNG_ALPHA_MODE_SUPPORTED correctly. 
This allows pngvalid to build when ALPHA_MODE is not supported, which is
required if it is to build on libpng 1.4.

0eadc27cd6 [devel] Added projects/owatcom, an IDE project for OpenWatcom to replace 
scripts/makefile.watcom.  This project works with OpenWatcom 1.9. The
    IDE autogenerates appropriate makefiles (libpng.mk) for batch processing.
    The project is configurable, unlike the Visual Studio project, so long
    as the developer has an awk.

b2bee3374c [devel] Make the 16-to-8 scaling accurate. Dividing by 256 with no rounding is 
wrong (high by one) 25% of the time. Dividing by 257 with rounding is
    wrong in 128 out of 65536 cases. Getting the right answer all the time
    without division is easy.

cc2770850a [devel] Revised documentation about png_set_user_limits() to say that it can 
only be used to reduce the defined limit, and that it also affects
png writing.

1921e6db90 [devel] Reversed earlier change of transformation order; move 
png_expand_16 back where it was before libpng-1.5.3beta07.
The change doesn't work because it requires 16 bit gamma tables when the code
only generates 8 bit ones.  This fails silently; the libpng code just doesn't
do any gamma correction.  Moving the tests back leaves the old, inaccurate, 8
bit gamma calculations, but these are clearly better than none!

cb0b29631f [devel] Documented png_set_alpha_mode(), other changes in libpng.3 and 
libpng-manual.txt.
  The cHRM chunk now sets the defaults for png_set_rgb_to_gray() (when negative
    parameters are supplied by the caller), while in the absence of cHRM
    sRGB/Rec 709 values are still used.
  The bKGD chunk no longer overwrites the background value set by
    png_set_background(), allowing the latter to be used before the file
    header is read. It never performed any useful function to override
    the default anyway.

f70c7d02e9 [devel] Added named value and 'flag' gamma support to png_set_gamma. Made a 
minor change from the previous (unreleased) ABI/API to hide the exact value
used for Macs - it's not a good idea to embed this in the ABI!

c5bef946b1 [devel] IDAT compression failed if preceded by a compressed text chunk 
This was because the attempt to reset the zlib stream in png_write_IDAT
happened after the first IDAT chunk had been deflated - much too late.
In this change internal functions are added to claim/release the z_stream
and, hopefully, make the code more robust.  Also deflateEnd checking is
added - previously libpng would ignore an error at the end of the stream.
