2312167d51 [libpng16] Increased warning buffer in pngerror.c from 128 to 192. 2012-01-23 22:34:15 -06:00

04336ba10f [libpng16] Add palette support to the simplified APIs. This commit 
changes some of the macro definitions in png.h, app code may need
corresponding changes.

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.

681c1fc02a [libpng16] Correct configure builds where build and source directories are 
separate.  The include path of 'config.h' was erroneously made relative in
pngvalid.c in libpng 1.5.7.

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.
