I just setup a new 64-bit Ubuntu 9.10 machine and ran into a nasty
problem with per pixel alpha. The minimal code fragment below works
correctly under 32-bit 9.04 (and lower) machines, but fails completely
under 9.10:
import pygame
pygame.init()
screen = pygame.display.set_mode((1024, 768), 0)
alpha = pygame.surfarray.pixels_alpha(\
pygame.Surface((1, 1), flags=0, depth=32).convert_alpha())
alpha[:] = 128
print alpha
Ubuntu 9.04 (pygame 1.8.1release + python 2.6.2)
[ [255] ]
Ubuntu 9.10 (pygame 1.8.1release + python 2.6.4)
[ [128] ]
Is this a bug? Or is the code I've been using for years to get per
pixel alpha values just plain wrong?? What's the OFFICIAL way to
instantiate a sprite with per pixel alpha?
Thanks,
