I use render images to create object textures / sprites on the fly. On windows, I am able to create a render image and it has all pixel values set to zero so I am able to treat it as a transparent canvas (no call to ClearScreen()). When I test on android, however, the images are not transparent and seem to have pixel data in them. Is there a difference between platforms and initilaisation of new images?

How can I get around this?

Probably. Different hardware. It's the same as AppGameKit variables being zeroed on creation, but C variables being uninitialised.

Call ClearScreen() before use?

Unfortunately if I use ClearScreen() then the alpha channel gets set to opaque. I guess I can use SetImageMask() to reset the alpha channel, but that's going to have a performance impact.

Actually, ClearScrren() seems to be doing the job. Strange, I'm sure that didn't happen before. Never mind
