I am developing application where I need to crop the empty part (white part) of the image to move it left. The picture format is JPEG and only 2 colors are used: white (background) and black (signature). Please see for below for a sample. How to do this on PHP?

If you want the image to stay the same size you'll need to extend the height and width back to the original values, but that should be a much easier problem to solve – iainn Nov 03 '21 at 14:18

Then the suggested duplicate about cropping whitespace should be everything you need – iainn Nov 03 '21 at 14:23
