The 

Channel

 object gives you access to much of the available functionality on Photoshop CS3 channels. 

You can create, delete, and duplicate channels or retrieve a channel's histogram and change its kind. See 

 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 

 for script samples that demonstrate how to create a selected area 

channel.

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:

Component channels are related to the document mode. Refer to Photoshop CS3 Help for 
information on channels, channel types, and document modes.
