This project, called image_paradise, allows you to manipulate images, primarily by using ImageMagick. For a more complete overview, have a look at the documentation, but just to give an overview - it is possible to animate .gif files, make use of gruff, or batch-generate automatically created image files through confree_generator (if you have cfdg installed). Images can be cropped through the toplevel method ImageParadise.crop(). class Optimizer can be used to optimize .jpg and .png files, if pngquant is installed.
