The Invert component inverts the curve provided by the Source input, converting its value at each point to its opposite: 0.05 to 0.95, 0.25 to 0.75, etc. This is a curve component, it can be located in the Curve Ops category on the Components Bar.
Invert: Map Input
When turned on, inverts the curve provided by the Source input. When turned off, the component has no effect. When a map component is connected to this input, the state of the checkbox is determined separately for different image areas by the brightness level of the image supplied by that component. The brightness level of 0 to 50 corresponds to unchecked Invert, and the level of 50 to 100 corresponds to checked Invert.
