:mod:`ImageChops` Module
========================
The :py:mod:`ImageChops` module contains a number of arithmetical image
operations, called channel operations (“chops”). These can be used for various
purposes, including special effects, image compositions, algorithmic painting,
and more.
For more pre-made operations, see :py:mod:`ImageOps`.
At this time, most channel operations are only implemented for 8-bit images
(e.g. “L” and “RGB”).
Functions
---------
Most channel operations take one or two image arguments and returns a new
image. Unless otherwise noted, the result of a channel operation is always
clipped to the range 0 to MAX (which is 255 for all modes supported by the
operations in this module).
