Line Annotation Object

The line annotation object (ANNOBJECT_LINE) is a simple line. With the automated functions, the line is started on a mouse-down event and completed on a mouse-up event.

The class for Line Annotation objects is LAnnLine.

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