Channel Swap
Substitutes the color value of a color channel with that of either a selected channel, or
its inverse. If you select Blue from Red, the value of blue in the object will match the value
of red across the entire object. The Channel Swap filter can be used in a variety of ways,
including simply inverting the alpha channel of an object.
