Hot Spot Annotation Object
Note: |
This topic is for Document/Medical only. |
The Hot Spot annotation object (ANN_OBJECT_HOTSPOT) is a rectangle that can be activated for an application-defined purpose. With the automated functions, in design mode, the rectangle contains a scaled image. The user clicks 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. Clicking on the button triggers an AnnClicked event.
For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.
With low-level functions, you must specify the defining rectangle. Other applicable properties have the following defaults, which you can change:
