Python Imaging Library (Fork)

Pillow is the friendly PIL fork by Jeffrey 'Alex' Clark and contributors. PIL is the Python Imaging Library by Fredrik Lundh and contributors. Development is supported by:

Overview

The Python Imaging Library adds image processing capabilities to your Python interpreter.

This library provides extensive file format support, an efficient internal representation, and fairly powerful image processing capabilities.

The core image library is designed for fast access to data stored in a few basic pixel formats. It should provide a solid foundation for a general image processing tool.
