from PIL import Image

##
# 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.
# 
# At this time, channel operations are only implemented for 8-bit
# images (e.g. &quot;L&quot; and &quot;RGB&quot;).
# 
# 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).
##

# with the given pixel value.

# @param image Reference image.
