The Python Imaging Library (PIL) adds image processing capabilities to your Python interpreter. This library supports many file formats, and provides powerful image processing and graphics capabilities.
This is a text (into image) distortion library. It is useful if you want to create a site which wants to keep out the various bots and ensure that a human is reading your page. The library is written in C and is based on various distortion modules, completely independed of the actual library (and easily programmable).
