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.

dff6f4c4f0 [libpng16Cleanup of png_set_filler(). This function does very different things 
on read and write.  In libpng 1.6 the two cases can be distinguished and
considerable code cleanup, and extra error checking, is possible.  This
makes calls on the write side that have no effect be ignored with a
png_app_error(), which can be disabled in the app using
png_set_benign_errors(), and removes the spurious use of usr_channels
on the read side.

905cc94e3d [libpng16] Don't check palette indexes if num_palette is 0 (as it can be in 
MNG files).

14ca47b453 [libpng16] Improved performance of new do_check_palette_indexes() function 
(only update the value when it actually increases, move test for whether
the check is wanted out of the function.

9ff37ea94f [libpng16] Fix an off-by-one error in the palette index checking function. 2012-03-10 20:03:06 -06:00
John Bowler
29a6ba01a7 [libpng16] Fixed build warnings (MSVC, GCC, GCC v3). Cygwin GCC with default 
options declares 'index' as a global, causing a warning if it is used as a
local variable.  GCC 64-bit warns about assigning a (size_t) (unsigned 64-bit)
to an (int) (signed 32-bit).  MSVC, however, warns about using the
unary '-' operator on an unsigned value (even though it is well defined
by ANSI-C to be ~x+1).  The padding calculation was changed to use a
different method.  Removed the tests on png_ptr->pass.

eeb1bb678d [libng16] Added palette-index checking while writing.

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.

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.

0a5c9c02fa [devel] Corrected const_png_ in png.h to png_const_ to avoid polluting 
the namespace.  Added png_get_current_row_number and
 png_get_current_pass_number for the
 benefit of the user transform callback.
 Added png_process_data_pause and png_process_data_skip for the benefit of
 progressive readers that need to stop data processing or want to optimize
 skipping of unread data (e.g. if the reader marks a chunk to be skipped.)
