#268 closed bug (fixed)

Transparent support broken for B_CMAP8

Looks like your recent BBitmap changes broke transparent handling for icons. Visible with the FileTypes application: all icons have white background, instead of shining through, as before.

This is actually a BeOS misbehaviour. BeOS uses the alpha channel of B_RGB32 like the one of B_RGBA32 even though according to GraphicsDefs.h and the BeBook B_RGB32 does not include an alpha channel at all. Fixed this by handling B_RGB32 and B_RGBA32 in the same way. Will commit the change when I get home today.

Even though BeOS might have this bug (dunno), I'm drawing B_CMAP8 bitmaps here, so I don't see the connection (even if this fix does the trick, at least I'm clueless) :-)

Ok, you are right, the problem was caused by converting the B_CMAP8 icon to B_RGB32 instead of B_RGBA32 before blitting it in the app_server. Changed this and will commit tonight.
