Editing Masks

Once you create a mask, you can edit its shape, mode, inner and outer edge softness, and other properties. To see the mask edges more closely, use the Magnify tool to zoom in. See Mask Toolbar.

To edit a mask:

1. In the Workspace panel, double-click the mask operator.



2. Show the Toolbar to access the mask tools, then click the Arrow tool and select a mask.

You can also select the mask object in the Workspace panel (below the mask operator).

3. On the Mask Controls panel, click Modes to edit the mask's color, opacity, feathering, mask mode, and other settings.
4. With the mask selected, click Transform on the Mask Controls panel to edit the mask's position, rotation, scaling, shear, and pivot point.

Note: You can also edit the mask's shape (scale), position, and rotation in the active viewport as you would any object.

5. To change the shape of the mask, click the Control Points option .

The mask bounding box is replaced by control points.

• Ctrl-drag (Windows) or Command-drag (Macintosh) on a linear control point (no tangents) to make it a Bezier control point with tangent handles that you can drag to change the shape of the curve.



• Press Ctrl (Windows) or Command (Macintosh) and click the Bezier control point to make it a linear control point.



The tangent lines disappears, the shape of the curve is flat at that point.

• Alt-drag on a point to adjust the length of both sides of the unbroken tangent handle at the same time.



• Press Ctrl (Windows) or Command (Macintosh) while dragging a tangent handle to break a tangent handle. Press Ctrl / Command again to make the handle continuous.
• Once a tangent handle is broken, you can continue working with the broken handle (pressing Ctrl / Command again will make the tangent handle continuous).



Note: Press Shift while dragging a tangent handle to rotate the handle in multiples of 45 degrees.

6. Drag the control points to give the mask a different shape.

Note: You can nudge the position of mask control points (in increments of one pixel) by selecting a point and pressing the arrow keys on the keyboard.



Note: To nudge the position of a control point in larger increments (of 10 pixels), hold Shift while pressing the arrow keys on the keyboard.

7. To add a control point, move the cursor over the mask's outline. When the cursor changes to a , click to add a control point.
8. Delete a control point by selecting it, and then pressing the Delete key.

Note: To delete a mask, select it and press the Delete key.
