:py:mod:`ImageChops` ("Channel Operations") 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).

|
|
|
Returns a copy of the image where data has been offset by the given
|
|
distances. Data wraps around the edges. If **yoffset** is omitted, it
|
|
is assumed to be equal to **xoffset**.
