Hello, I'm wondering the best way to apply alpha from one surface onto another -
I can get the alpha with pygame.surfarray.array_alpha But can't see a corresponding way to apply that to a surface without affecting the rgb values. Basically I have two images, one paletted, I manipulate the palette then blit it onto a 32 bit surface. The second image has the alpha, I want to apply this to the surface, keeping the rgb values - basically a very quick way of colourising things.
