Masking an Image

In the following example, a garbage mask is added to the matte from the previous

“Creating a Key” section.

To mask an image:

1 In the Layers tab or Canvas, select the object with the applied keying filter, or the filter

itself.

In the Toolbar, the Mask tools become available.

2 In the Toolbar, select the Bezier (default) Mask tool.

The pointer changes to a pen.

3 In the Canvas, click around the image area you want to remove (in this example, the

grass at the elephant’s feet).

Note: To create tangent handles as you draw the mask, drag outward as you add the

control points.

4 To close the mask, click the first point drawn, or press C.
