Decompose separates an image into its constituent color channels, each in a separate layer. The current image (including all layers) is rendered to an image which is then separated in channels as determined by the chosen color space (e.g. RGB, CMKY, etc). The output may be rendered as either independent gray-scale channels or as a composite image consisting of colored channel representations.

If the image has transparent/translucent pixels, a layer for the alpha channel is generated as well.
