--- Comment #3 from Jan-Peter Nilsson peppe@bsnet.se 2009-05-04 00:20:23 --- Created an attachment (id=20898) --> (http://bugs.winehq.org/attachment.cgi?id=20898) A hack using hbmMask to populate the alpha channel
This is not a solution, just a hack verifying my assumption. I'm using hbmMask from IPicture to set the pixel format to ARGB in GdipLoadImageFromStream and to populate the alpha channel in GdipBitmapLockBits.
I'm using an offset into OLEPictureImpl to get hold of hbmMask, as it (as far as I can tell) is not otherwise available outside of the implementation. I'm not proposing this is something that should be done.
Using this the launcher window appear.
