Ellipse Mask [Elp]

The Ellipse Mask is most useful for masking round objects. It is a circle by default but independent control is offered over the width, height and angle, providing for a wide variety of ellipsoidal shapes.

Many of the controls found in this mask tool are common to all mask tools. These controls are documented at Common Mask Controls.

Controls Tab

Level, Filter, Soft Edge and Border Width

Please refer to the Common Mask Controls.

Width

This control allows independent control of the ellipse mask's Width. In addition to the slider in the mask's controls, interactively drag the width (left or right edge) of the mask on the view using the pointer. Any changes will be reflected on this control.

Height

Height allows independent control of the ellipse mask's height. In addition to the slider in the mask's controls, interactively drag the height (top or bottom edge) of the mask on the view using the pointer. Any changes will be reflected on this control.

To change the mask's size without affecting the aspect ratio, drag the on screen control between the edges (diagonal). This will modify both the width and height proportionately.

Angle

Change the rotational angle of the mask by moving the Angle control left or right. Values can be entered in the input boxes provided. Alternately, use the onscreen controls by click-dragging the little circle at the end of the dashed angle line to interactively adjust the rotation of the ellipse.
