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...
