PIL(low) talk¶
The "classic" Python Image Library (or PIL) is described in the (classic) handbook: http://www.effbot.org/imagingbook/pil-index.htm
In fact, the current library that people tend to use is called Pillow, but as a "friendly fork" it tries to acts just like the old PIL library, so you don't even notice (and your code still uses the name PIL). The Pillow project also maintains it's own documenation at:
