Most efficient way to get pixelcolors of an image?

[defn noob]

i want to process a large number of images and store their respective
pixels in a matrix.

what is the mostt efficient way of opening and checking them?
i doubt pygame is made for this purpose :)

i guess i could also use tkinter?


and why cant i print out matrix after getting the pixels? do i have to
deinit() pygame somehow?

import pygame
import sys
import os

print os.path.exists( 'C:/users/saftarn/desktop/images/bloba.bmp')

pygame.init()
screen = pygame.display. set_mode((800, 600))

image = pygame.image.lo ad('C:/users/saftarn/desktop/images/bloba.bmp')
imrect = image.get_rect( )
imrect = imrect.move(200 , 200)

matrix = []

while 1:
pygame.display. flip()
screen.fill((25 5,255,255))
screen.blit(ima ge, imrect)
pygame.event.wa it()
event = pygame.event.wa it()

for x in range(1, 301):
for y in range(1, 301):
matrix.append(s creen.get_at((x , y)))

#print matrix
if event.type == pygame.QUIT:
#print matrix
sys.exit()

Most likely PIL (Pyhton Imaging Library).

this just shows a GUI that normally shows pictures but it doesnt show
any picture...


from PIL import Image

im = Image.open('C:/Users/saftarn/Desktop/images/giffer.gif')
im2 = Image.open('C:/Users/saftarn/Desktop/images/blob.jpg')

im.rotate(45).s how()
im2.show()
