sanpera is an image-editing Python library powered by ImageMagick.
While sanpera uses ImageMagick, it isn't designed as an ImageMagick wrapper; the underlying library is a mere implementation detail. The goal is to support all of ImageMagick's features with an idiomatic interface.
The examples from the ImageMagick Usage documentation are gradually being converted into unit tests in sanpera/tests/im_usage. An easy way to learn sanpera, then, is to find an example that does what you want and read the test's equivalent Python code.
