The Standard Ellipse Tool draws solid or hollow circular or oval shapes. To draw an ellipse, position the mouse cursor over your picture where you want the top left side of the ellipse to begin. Hold down the left mouse button and drag the cursor to where you would like the opposite side. When your ellipse reaches the desired size and shape, release the mouse button.

You can enable the Option Panel's Anti-alias option to smooth the edges of the shape.

To create an ellipse without a border, set the Line Width slider on the Option Panel to zero. A hollow ellipse can be created by selecting the Hollow/No Fill button from the Fill Selector.
