20e0daa74a [libpng15] Update CHANGES and ANNOUNCE about rowbytes fix 2015-10-30 13:02:20 -05:00
John Bowler
8678f9c3f4 rowbytes check correction 
The old code incorrectly calculated the output rowbytes when the
application decreased either the number of channels or the bit depth (or
both) in a user transform.  This was safe; libpng overallocated buffer
space (potentially by quite a lot; up to 4 times the amount required)
but, from 1.5.4 on, resulted in a png_error.

e87d502b16 png_set_filler with 16-bit output byte swapped the value 
A simple case of assigning the low and high byte in the wrong order, may
cause problems for some apps if they already have a work-round.  The
code executes before the 16-bit byte swap so the order is always the PNG
one.

84dc479108 [libpng15] De-configured build fixes to make a range of deconfiguration options 
(such as switching off read or write support) work in more cases.  Also
upgraded pngtest and pngvalid to the libpng 1.6 versions (with some
modifications) which provide more extensive testing.  Replaced pngtest.png
because pngtest writes the ancillary chunks in a different order.

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.

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.
