The :pyImageChops 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 :pyImageOps.
At this time, most channel operations are only implemented for 8-bit images (e.g. “L” and “RGB”).
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).
