(Document and Medical Imaging toolkits)
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.
