Mask drawing


The mask tools are used for drawing masks directly onto layers in the Viewer.

Detailed information on creating and using masks can be found in the Masking chapter.

Mask tools

There are three mask tools for use in the Viewer, each creating different shapes.

You must have a layer selected on the timeline or in the Viewer to use the mask tools.

The Freehand Mask tool is for creating your own mask shapes and editing shapes you have already created.

With the Freehand Mask tool selected you can click on the Viewer to draw points. Clicking and dragging creates a curved line, while clicking and releasing creates a linear, straight line.

The shape of curved points can be further adjusted using the extension handles.

You can change the type of any point by right clicking on it and choosing the required type from the menu:

Make Curved Locked - both extension handles work in tandem. Adjusting one will adjust the other simultaneously. This is useful for maintaining smooth curves.
Make Curved Unlocked - the extension handles can be adjust separately. This is useful for creating sharp corners while retaining a curved line.
Make Linear - the point forms an angled corner and the line either side is straight.

To activate a freehand mask you must close it. To do this simply click again on the first point you created. The mask will close and activate.

For more information on mask properties and editing your masks, check out the Masking chapter.

RECAP The mask tools work together with the Masking controls. You use them to draw your mask shapes directly onto the Viewer.
