7342fcaf92 [libpng] #define PNG_ALIGN_TYPE PNG_ALIGN_NONE in contrib/pngminim/*/pngusr.h 2011-10-27 19:56:36 -05:00

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.

ef02d563a3 [libpng15] Added LSR() macro to defend against buggy compilers that evaluate 
non-taken code branches and complain about out-of-range shifts.

c9e27d026d [libpng15] Made png_ptr->prev_row an aligned pointer into png_ptr->big_prev_row 
and removed a redundant assignment (Mans Rullgard).

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.

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.

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.

8e25a61277 [libpng15]` Revised test-pngtest.sh to report FAIL when pngtest fails. 
Added "--strict" option to pngtest, to report FAIL when the failure is
only because the resulting valid files are different.
