ImageChops
(“Channel Operations”) Module¶
The 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 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).
- PIL.ImageChops.offset(image, xoffset, yoffset=None)¶
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.
