I can't think of a way to set the alpha by itself, without setting the RGB. Say I wanted to set the alpha ONLY with fill() then I don't think I can do it. Is there some way you could do that by passing mask to a blit call? If there's no way to do it already, then perhaps we could create a separate function which only acts on one channel at once. eg, only R, or only A. This could be added as a 'special flag' the same way the BLEND_ADD etc have recently been added to Surface.fill() Or maybe I'm forgetting some way?

Hi, I have a couple of questions regarding surfaces with an alpha channel. 1. Is this the correct way of creating an surface with an alhpa-per-pixel channel? surface = pygame.Surface((w, h), pygame.SRCALPHA) 2. How do you clear an alpha channel surface? I guesss you can't use the fill method? Best Regards /John
