    The box is (left, upper, right, lower) so maybe you meant (2407, 804, 2407+71, 804+796)?

    Edit: All four coordinates are measured from the top/left corner, and describe the distance from that corner to the left edge, top edge, right edge and bottom edge.

    Your code should look like this, to get a 300x200 area from position 2407,804:

    left = 2407
    top = 804
    width = 300
    height = 200
    box = (left, top, left+width, top+height)
    area = img.crop(box)

    Try this:

    it's a simple code to crop an image, and it works like a charm ;)

    import Image
    
    def crop_image(input_image, output_image, start_x, start_y, width, height):
        """Pass input name image, output name image, x coordinate to start croping, y coordinate to start croping, width to crop, height to crop """
        input_img = Image.open(input_image)
        box = (start_x, start_y, start_x + width, start_y + height)
        output_img = input_img.crop(box)
        output_img.save(output_image +".png")
    
    def main():
        crop_image("Input.png","output", 0, 0, 1280, 399)
    
    if __name__ == '__main__': main()
    

    In this case the Input image is 1280 x 800 px and the croped is 1280 x 399px starting at the top left corner.
