192e92d681 [libpng16] Fixed some indentation to comply with our coding style. 2016-07-13 14:43:42 -05:00

01a0e8062d [libpng16] Reverted addition of png_set_filler_16 and png_set_add_alpha_16() 
functions. They unnecessarily duplicate png_set_filler() and png_set_add_alpha()
which now work properly with 16-bit images.

efe4e5d10d [libpng16] Reverted the fix of byte order in png_do_read_filler() with 16-bit 
input that was made in version 1.6.17beta01, to preserve legacy
behavior even though it was incorrect.  Instead, added new API
png_set_filter_16() and png_set_add_alpha_16() that set a flag to
make png_do_read_filter() interpret the filler bytes properly.

61ea3eacb0 [libpng16] Reverted use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING 
in the manual, example.c, pngtest.c, and applications in the contrib directory.
It was incorrect advice.

cad0150d12 [libpng16] Corrected handling of row_pointers in example.c and added some 
comments.  It has apparently been wrong since libpng-1.0.1c (confusing
use of a 1D and a 2D array for the image source).

f2715a558a [libpng16] Revised example.c to put text strings in a temporary character array 
instead of directly assigning string constants to png_textp members.
This avoids compiler warnings when -Wwrite-strings is enabled.

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.
