Well, you could try getting the alpha array via pygame.surfarray.pixels_alpha and then running: alphas[...] = 128 # Sets all alpha values to 128.
Might have to run it through Surface.convert_alpha before it's got an alpha array to work with, though. -FM On Sat, Oct 4, 2008 at 11:47 PM, Ian Mallett <[EMAIL PROTECTED]> wrote: > On Sat, Oct 4, 2008 at 8:51 PM, Brad Montgomery <[EMAIL PROTECTED]> > wrote: >> >> Would something like PIL's putalpha do what you want?
