Copy

Function
The Copy function copies selected channels from Image B to Image A (replacing the images entirely). It is common to copy over the alpha channel. To copy channels within the same image, use Reorder. SwitchMatte depends on Copy, but is a macro with MMult and Invert placed inside of the node.
