Libpng 1.7.0beta30 - January 30, 2014
Libpng 1.7.0beta30 - February 1, 2014
This is not intended to be a public release. It will be replaced
within a few weeks by a public version or by another test version.
@ -496,7 +496,13 @@ Version 1.7.0beta28 [January 20, 2014]
Version 1.7.0beta29 [January 30, 2014]
Quiet an uninitialized memory warning from VS2013 in png_get_png().
Version 1.7.0beta30 [January 30, 2014]
Version 1.7.0beta30 [February 1, 2014]
Fixed a large number of instances where PNGCBAPI was omitted from
function definitions.
Added pngimage test program for png_read_png and png_write_png. This
is a work-in-progress, no tests are run automatically at present and
the program by virtue of exhaustively testing all the transforms is
very slow.
