Comp Ops Tool

The Comp Ops tool lets you apply a variety of compositing operators to two source images.

To apply Comp Ops operations:

1. Drag a Comp Ops tool from the Composition folder in the Tools tab to the dependency graph in the Schematic view.
2. Connect a source image to input A and another source image into input B of the Comp Ops node.
3. Click the Operator button and select a compositing operator.

   Select:	To:
   A over B	Place input A on top of input B according to the alpha of the foreground image.
   B over A	Place input B on top of input A according to the alpha of the foreground image.
   A in B	Place the RGBA of input A into the alpha of input B.
   B in A	Place the RGBA of input B into the alpha of input A.
   A out B	Place the RGBA of input A into the invert alpha of input B.
   B out A	Place the RGBA of input B into the invert alpha of input A.
   A atop B	Place the RGBA of input A over the RGBA of input B but through the alpha of input B.
   B atop A	Place the RGBA of input B over the RGBA of input A but through the alpha of input A.
   A xor B	Create the union of the RGBA of inputs A and B minus the intersection of the RGBA of inputs A and B.
