Sorry i don't understand the question. Do you want to place a transparent bitmap on the canvas? Or do you want to see the desktop or something what is behind your application? Like a sort of overlay.
At least a2dAggDrawerRgba has an alpha channel. But never tried it. In principle a a2dCanvas is a wxWindow, so if you can do such a thing with a wxWindow, it can be done here. But maybe you prefer without a double buffer approach, and instead just draw objects. Like a2dDcDrawer is used to draw on a printer without bitmap in between. But again it not clear to me what you want.
