The AnnHotspotObject object is designed to work as a scaled picture drawn inside a rectangle. The AnnHotspotObject object will draw the picture if the owner container is in design mode. If the container is in run mode, the AnnHotspotObject object will not draw the picture.
With the automated functions, in design mode, the rectangle contains a scaled image. The user clicks / taps and drags to specify the rectangle in the current window. In run mode, the object is transparent, but the mouse pointer changes to a hand when it is over the object.
Programmatically, the boundaries and location of the hotspot object can be controlled using the following properties:
Each object can be transformed with the following methods:
The AnnHotspotObject class inherits a number of properties from the AnnObject class, providing support for font, stroke and fill characteristics. These properties are listed below:
The name of the hotspot object can be controlled using AnnObject.Labels property, inherited from the AnnObject class.
An object can be part of a group annotation object or part of a container object. It cannot be part of both a group and a container at the same time.
The following properties can also be used to programmatically set characteristics of an AnnHotspotObject:
