The freehand hot spot annotation object is designed to work as a scaled picture drawn inside a collection of points that create a sequence of joined lines. The freehand hot spot object will draw the picture if the owner container is in design mode. If the container is in run mode, the freehand hot spot object will not draw the picture.
