Hi, I'm trying to use convert -crop to create equally sized tiles (for some sort of mapping software). The problem is that with some images I can't get 10x6@ tiles, for some images I can't even do 9x6@. When I run some math and do the same crop with variables (width and height) it's working fine. An...
