Working with Channel objects The Channel object gives you access to much of the available functionality on Photoshop channels. You can create, delete, and duplicate channels or retrieve a channel's histogram and change its kind. See "Creating New Objects in a Script" on page 23 for information on creating a Channel object in your script. You can set or get (that is, find out about) a Channel object's type using the kind property. See "Loading and storing selections" on page 45 for script samples that demonstrate how to create a selected area channel. Changing channel types You can change the kind of any channel except component channels. The following examples demonstrate how to change a masked area channel to a selected area channel: NOTE: Component channels are related to the document mode. Refer to Photoshop Help for information on channels, channel types, and document modes.
