在Pygame中使用Pillow / PIL

Question

I'm currently trying to use a .png of a Tic Tac Toe board in Pygame so that the white part is transparent. However, I'm getting "libpng warning: sBIT: invalid" and the white is showing when I blit the board onto the background. The code is as follows:

background = pygame.image.load("blah.bmp")
board_surface = pygame.image.load("board.png")
board_surface.convert_alpha()

I read on the Pygame docs that only .bmp is guaranteed to work, and since image.get_extended() is returning a 1, I'm assuming that I simply don't have enough image processing support.

I've installed Pillows and imported the module, but I have no idea how to use this with Pygame. The tutorial shows how to load images as Pillow's Image class and so forth, but I need to represent images as Pygame's Surfaces.

I would appreciate any help with integrating these two things, or any other solutions on how to get my .png to work! For reference, I'm using Python3.3 and Pygame1.9.2

Answer 1

I have encountered this problem too. I solved it by switching to .tif (only with one f !). If you have Gimp installed use that to turn the white spaces into alpha=0 spaces (if you have problems doing that I can help with a more detailed explanation). After that import the image just as normal and use the .convert_alpha() method.
