I'm trying to create an Automator folder action to automatically crop images that are added to a specific folder. It works; however, it crops the images towards the center. How can I crop starting from the right edge? I found Propper Cropper, which looks like it does what I need, but unfortunately it was compiled for PPC, and is therefore not a universal action. Is there an alternative (preferably an Automator action)? If this is not possible with Automator, is there some other software I can download to achieve this?
Install Homebrew and then install ImageMagick with
