I was trying to make some data exported from cairo as a ARGB (literally
in this byte order on my big-endian machine, A beign in the lowest
address) buffer into a PyGame surface but run in to some problems.
The code which creates the bitmasks required by the SDL conversion
routine does some really strange things.
For RGBA it takes the notation as a literal byte order in memory, low
address first and simply swaps the 4 bytes on BE vs. LE.
I'm not sure the problem. Passing the mask arguments when creating
surfaces should allow any byte orderedering.
size = 100, 100
rgba_mask = 0xff000000, 0xff0000, 0xff00, 0xff
rgba_surf = pygame.Surface(size, 0, 32, rgba_masks)
argb_mask = 0xff0000, 0xff00, 0xff, 0xff000000
argb_surf = pygame.Surface(size, 0, 32, argb_masks)
I was thinking about pygame.image.frombuffer which requires a string
(and not an arbitrary bitmask tuple). I don't think pygame.Surface
allows for creating surfaces out of arbitrary python buffers.
