Line Annotation Object

Note: This topic is for Document/Medical only.

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.

With low-level functions, you must provide the points that define the line. 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.
Foreground color	Defaults to black. It can be changed using the AnnSetForeColor 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.
Tag (identifier)	Defaults to 0. It can be changed using the AnnSetTag method.
Window handle	Defaults to NULL or the handle inherited from the container. It can be changed for all objects using the AnnSetWnd method.
User mode	Defaults to design mode or the mode inherited from the container. It can be changed for all objects using the AnnUserMode property.
