Hi, I've tried your script, but I have a problem. My pictures are from a scanned book, opened, with a lot of black around the book. I want to crop the black borders, but not completely, so I want to expand the selection by 25 pixels instead of 2. I've changed the "expandSelectionBy(2)" to "expandSelectionBy(25)" but it doesn't work, the result is the same. What should I do? Is there something else I should change? I hope you can help me.
