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 show the name, with the name as the empty string. It can be changed using the AnnSetName method.
Line width	Defaults to 1. It can be changed using the AnnSetLineWidth method. (Values equate to a minimum of 1 pixel when displayed.)
Line style	Defaults to solid. It can be changed using the AnnSetLineStyle method.
ROP2	Defaults to Copy. See ROP2 Dialog Box for Annotations
Foreground color	Defaults to black. It can be changed using the AnnSetForeColor method.
Background color	Defaults to white. It can be changed using the AnnSetBackColor method.
Font size	Defaults to 10 point, translated with a scaling factor of 1. It can be changed using the AnnSetFontSize method.

Protractor	Defaults to the acute angle, measured in degrees, to a precision of two places right of the decimal, and an arc radius of 30. These can be changed using the AnnSetProtractorOptions method.
Tag (identifier)	Defaults to 0. It can be changed using the AnnSetTag method.

	To get the angle of the Protractor object in the object's unit of measurement, use AnnGetAnglemethod.
