Protractor Tool

(Document and MedicalImaging toolkits)

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. Holding down the Shift key while drawing either of the two lines will draw the line at an angle that is a multiple of 45 degrees.
