I am a programmer who likes to make sure his code is compatible with Windows, Linux and Mac through Wine. I would like to ask if there is a known issue with the Wine parallelogram blitter because I am trying to use the PlgBlt function from the gdi32.dll and it completely ignores my mask. Well, I say that it ignores my mask… actually, it allows images to show through the fully white areas of the mask but renders the black parts as black rather than transparent. I know that I am making the API call correctly as it works on Windows. Is anyone else having any transparency issues either as a programmer or user, in particular those involving black backgrounds showing up where transparency should be?
Any help on this matter would be greatly appreciated.
