Chapter 1 An Overview of the Shake User Interface 87

There may be cases, however, where you want to take advantage of the DOD for

masking purposes. In this tree, an image is scaled down, and the brightness increased

with an Add node. This, however, turns the area outside of the image a medium gray.

Since this area is recognized as outside of the DOD, it can be returned to black with a

Color–SetBGColor node, which sets the color for the area outside of the DOD.

The Layer–Constraint node also limits a process. For more information on masking

using the Constraint node, see Chapter 19, “U

sing Masks,” on page 527.
