Freehand Line Annotation Object

The freehand annotation object (ANNOBJECT_FREEHAND) is an array of points that create a sequence of joined lines. With the automated functions, each line segment is formed with a mouse move event when the left button is down, and the object is completed on a mouse up event.

The class for Freehand Line Annotation objects is LAnnFreehand.

For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.

With low-level functions, you must provide the points that define the shape of the object. Other applicable properties have the following defaults, which you can change:
