MiniMagick gives you access to all the command-line options ImageMagick has (found at http://www.imagemagick.org/script/mogrify.php). Using MiniMagick as an alternative to RMagick allows the Ruby processes memory to remain small because it spawns ImageMagick's mogrify program, which has much lower memory usage than RMagick.
