import pygame

pygame.init()
screen = pygame.display.set_mode( (640, 480) )
andre = pygame.image.load('andre16.bmp')
screen.blit( andre, (0,0) )

input("Press enter to continue..")
pygame.quit()



I am trying to load a bitmap using pygame. The code shown above is what I tried. It is suppose to blit the bitmap to the screen, but I get nothing. Can someone tell me what I'm doing wrong. Thanks in advance, Glen.

After you draw a frame, call pygame.display.flip(). Pygame uses double-buffering, so you're drawing your images to one surface, while another surface is visible on-screen. After you're done, you flip the two, so the latest stuff becomes visible on-screen. Without double-buffering, you could be drawing an image to the screen while the screen is refreshing, which often leads to tearing effects.
