I have a image of some rectangles and I want to draw a line across some of the rectangles. How can I count the pixels along the line and find out which part has the minimum intercepts?
Thanks, Gene

Let's say you drew the line with improfile(). Then you'll have the endpoints of the line and you can use the Pythagorean theorem to get the distance.
I don't know what you mean by the part that has the minimum intercepts. Perhaps uploading an image and a better explanation would help.
