Rectangular Masks

Use the rectangular mask to mask out a rectangular portion on the current layer. In the following example, a rectangular mask is used to partially isolate the subject (Little Mermaid) from its original background and composite it over the back layer.

To draw a rectangular mask:

1. Select the front layer (the layer to which you want to add a mask).
2. Choose Operators | Mask | Rectangular Mask.

The mask operator opens and a default size rectangular mask is added to the layer.



3. On the Toolbar, click the Arrow tool .
4. In the viewport, use the bounding box to adjust the size and rotation of the rectangular mask. For more information, see Editing Object Transform Properties.
5. Click the Back button to return to the composite and see the results of the masking operation.

Note: To switch back to the mask operator to make more adjustments, click the Forward button. You can also double-click an operator in the Workspace panel to make it current.
