Remarks

The hot spot annotation object is designed to work as a scaled picture inside a rectangle. The hot spot object will draw the picture if the owner container that is in design mode. If the container is in run mode, the hot spot object will not draw the picture.

The AnnHotspotObject class inherits the AnnImageObject class and accesses the common AnnImageObject.Picture property mentioned above through this inheritance.

For more information about the hotspot annotation object refer to WPF AnnHotspotObject. For more information about the automated hotspot annotation object, refer to WPF Annotation Objects - Automated Features and WPF Automated Annotations - Hotspot Picture Tab.
