Thanks for the tip. I read the docs for mogrify just now, but it says it overwrites images and I don't see any option to change that or add a different output path. The need here is to take a source image from a folder like drawable-hdpi, and produce a new, converted image in a folder like drawable-ldpi. I guess maybe you could copy everything first, then modify it? Although that seems more clumsy than just running the find command already being used. Thanks for the help!
