I wanted to use pyCairo with pyGame but can’t find any sample on the net.
So, here is a little bit of code to do this without using pyGTK.
#!/usr/bin/env python
import cairo
import pygame
import array
import math
def draw(surface):
x,y, radius = (250,250, 200)
ctx = cairo.Context(surface)
ctx.set_line_width(15)
ctx.arc(x, y, radius, 0, 2.0 * math.pi)
ctx.set_source_rgb(0.8, 0.8, 0.8)
ctx.fill_preserve()
ctx.set_source_rgb(1, 1, 1)
ctx.stroke()
def input(events):
for event in events:
if event.type == pygame.QUIT:
sys.exit(0)
else:
print event
#Create Cairo Surface
Width, Height = 512, 512
data = array.array('c', chr(0) * Width * Height * 4)
stride = Width * 4
surface = cairo.ImageSurface.create_for_data (data, cairo.FORMAT_ARGB32,Width, Height, stride)
#init PyGame
pygame.init()
window = pygame.display.set_mode( (Width,Height) )
screen = pygame.display.get_surface()
#Draw with Cairo
draw(surface)
#Create PyGame surface from Cairo Surface
image = pygame.image.frombuffer(data.tostring(),(Width,Height),"ARGB",)
#Tranfer to Screen
screen.blit(image, (0,0))
pygame.display.flip()
while True:
input(pygame.event.get())

Notes
- This is working on Linux and Windows.
- I’m using pyGame 1.7.1. There seems to be a bug in the surface creation with the “ARGB” byte order…
