i can't find that in the documentation. do you know where it says that?

> FWIW, this doesn't render the graphic transparent.

a very important point i just remembered: you need to be using
wxWindows 2.5.0 or later. previous versions do not support transparent
PNG. maybe this is your problem.

> Which values does alpha_data need?  Just True/1?

alpha_data must be a character array of values between 0 and 255.
There must be one alpha value for each image pixel. This array is used
if the image data itself does not contain alpha information (PNG is
the only supported format that does).
