Hi, I need to check lot of images to see if they have the right logo in them. Fortunately I know the co-ordinates of where the logo in the image should be but I'm not sure on the best way to compare a selection from the image with a template. Currently I'm cropping the target image to the right size and comparing it with ImageChops.difference() with the template but I'm not sure how to interpret the results - I had hoped for either a largely black or white image but I'm largely getting the inverse of the logo. Any tips?
