Protractor Annotation Object

Note:

This topic is for Document/Medical only.

The protractor annotation object (ANNOBJECT_PROTRACTOR) consists of two simple lines joined at a vertex to create an angle. With the automated functions, the first line of the protractor is started on a mouse-down event and completed on a second mouse-down event. The second line is completed on a third mouse-down event.

With low-level functions, you must define the size and position of the rectangle. Other applicable properties have the following defaults, which you can change:

Visible	Defaults to FALSE. It can be changed using the AnnSetVisible method.
Selected	Defaults to FALSE. It can be changed using the AnnSetSelected method.
Name	Defaults to an empty string. It can be changed using the AnnSetNameOptions method.
