--- Comment #33 from Vincent Povirk madewokherd@gmail.com 2013-08-14 14:58:20 CDT --- Oh, actually that's pretty much the same as Samuel's last patch, which was a partial revert. The code looks right to me (a WIC encoder can set a different pixel format from the one requested, in which case it's up to the caller to convert the image data to that format), so I wonder why Dmitry's patch removed it.
