Ellipse Annotation Object

Note:

This topic is for Document/Medical only.

The ellipse annotation object (ANNOBJECT_ELLIPSE) is a simple ellipse. With the automated functions, the user clicks and drags to specify the ellipse in the current window.

For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.

With low-level functions, you must specify the defining rectangle. Other applicable properties have the following defaults, which you can change:

Visible

Defaults to FALSE. It can be changed using the L_AnnSetVisible function.

Selected

Defaults to FALSE. It can be changed using the L_AnnSetSelected function.
