What size image are you requesting and what size are you drawing it as?
I've noticed that there is some crud around the edges of the image
content on XP, that is turned into the shadow on the native dialog.
It's probably some alpha blending info that is just getting converted to
a flat mask in wxArtProvider someplace. (Other than that, the rest of
the 32x32 image looks okay.)
I'm requesting the default size (not supplying the size argument) and
drawing without scaling. On second viewing you're probably right that this
is an artefact of the alpha channel being flattened. Do you know at what
point the this happens? Any chance I could get it out of ArtProvider, into
PIL and composite it onto my background colour before loosing the alpha
channel? Otherwise there's not a lot I can do, other than wait for wxPython
2.5, right?
Cheers,
Rich
