I see. In that case, you can't use the method I described; that only
works if you load the image from disk (as far as I know). I think you'd
better use getdata() as Alan described.
Something like this, if you need to access the pixels column-by-column
(Is that really what you want? You still haven't told us):
# ...
image = ImageGrab.grab ((rect.left, rect.top, rect.right, rect.bottom))
pixels = image.getdata()
for x in xrange(0, 1024):
for y in xrange(0, 768):
print pixels[x + y * 768]
Note: pixel indices start from 0, not from 1.
If you want to access them row-by-row (as is generally more often the
case) and you don't have a special need to have the x and y available:
image = ImageGrab.grab ((rect.left, rect.top, rect.right, rect.bottom))
for pixel in image.getdata():
print pixel
Anyway, you're printing a lot of pixels (786432 actually)... is that
really what you want?
