i originally had a similar problem, in that i wanted the bytes of a
png image of everything i was drawing with floatcanvas, so i do this
I = wx.ImageFromBitmap(Canvas._ForgroundBuffer)
pil = Image.new('RGB', (I.GetWidth(),I.GetHeight())
pil.fromstring(I.GetData())
imageData = StringIO.StringIO()
pil.save(imageData,format='PNG',optimize=True)
return imageData.getvalue()
not sure if it's useful to you, but I hope that helps.
