Reorder
The Reorder node lets you shuffle channels. The argument to this command specifies
the new order. A channel can be copied to several different channels. The letter “l”
refers to the luminance pseudo-channel which can be substituted in place of the RGBA.
If an expression is on a channel that does not exist, Shake creates the channel. You can
use the Z channel as well. For example:
shake -reorder zzzz
places the Z channel into the RGBA channels for viewing.
To copy a channel from another image, use the Copy node.
