The Angle Measurement Tool

The angle measurement tool is used to measure angles in an image.

To make an angle measurement, you have to specify three points. Click the mouse on the first point, then again on the midpoint and again on the last point. After selection of the third point, the angle measurement dialog will appear. The angle measurement dialog displays the angle you just selected. By selecting the Draw Line and Label check boxes, you can show the measurement on the image. Pressing the text button allows you to edit the label text and to change the font used for the label (see The Text Tool for more information).

The measurement will be placed in the overlay as three separate objects-two lines and the label. Each of these can be manipulated independently.
