Freehand Hot Spot Annotation Object

(Document and Medical Imaging toolkits)

The Freehand Hot Spot annotation object (ANNOBJECT_FREEHANDHOTSPOT) is an array of points that create a sequence of joined lines. With the automated functions, in design mode, 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. In run mode, the object is transparent, but the mouse pointer changes to a hand when it is over the object. Clicking on the button sends a WM_LTANNEVENT message that indicates an activation event.

You can change the points of a Freehand Hot Spot object using the L_AnnGetPoints and L_AnnSetPoints functions.
