Eliminating the Border Around a Generated Image
16 views (last 30 days)
I am creating images using the rectangle() function with various line and space sizes. I attached an example image to this question. I want to eliminate the border of white that surrounds the black rectangles. (It affects my pixel count calculations.) Currently, I am just using the imcrop() function, but the cropping dimensions have to change according to the line and space sizes. Is there a more efficient way than imcrop()?

There is a function that will do this for you in one step, but I forgot what it's called. Here's a primitive solution for you!
Basically you find the upper left and bottom right corners, and then crop a rectangle between those.
