"""
with pycairo 1.4.12 and pygame 1.7.1 you get the error message:

Traceback (most recent call last):
  File "./pygame-test1.py", line 42, in <module>
    image = pygame.image.frombuffer(buf,(Width,Height),"ARGB",)
TypeError: char buffer type not available

This is because with
    buf = surface.get_data()
pycairo provides a binary image buffer,
whereas with
    image = pygame.image.frombuffer(buf,(Width,Height),"ARGB",)
pygame is expecting a text-based character buffer!
