Use this property to associate a data channel with the alpha channel of an output image.

Color channel assignments are not exclusive i.e. the same data channel can be associated with more than one output color. If no alpha channel data was available upon instantiation of the current object, this property defaults to -1. Likewise, to disassociate alpha data from an output image alpha channel, assign this property the value of -1.
