--- Comment #27 from Anastasius Focht focht@gmx.net 2013-05-09 12:50:46 CDT --- Hello folks,
maybe Dmitry can attach a cleaned up version, incorporating his additional findings (comment #23) which should work for WPF 3.0 and 3.5 Though 3.5 SP1 behaviour still needs to be investigated ...
WPF 4.x doesn't seem have any problems connected to this bug (windowscodecs interfaces), most likely due to different engines/code rewrite.
Regards
