Each tiff file has 4 images in it. I do not wish to extract and save them if possible, I would just like to use a for loop to look at each of them. (Like look at the pixel [0,0] )and depending on what color it is in all 4 I will do something accordingly.
Is this possible using PIL? If not what should I use.
You can use the "seek" method of a PIL image to have access to the different pages of a tif (or frames of an animated gif).
from PIL import Image
img = Image.open('multipage.tif')
for i in range(4):
try:
img.seek(i)
print img.getpixel( (0, 0))
except EOFError:
# Not enough frames in img
break
