Freehand Hot Spot Annotation Object
Note: This topic is for Document/Medical only.
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 triggers an AnnClicked event.
You cannot flip, reverse, or rotate a hot spot. If you flip, reverse, or rotate a container that includes a hot spot, the object will move to the new position, but will retain its orientation.
The points can be changed using the AnnGetPointX method, AnnGetPointY method and AnnSetPoints method.
With low-level functions, you must define the size and position of the rectangle. Other applicable properties have the following defaults, which you can change:
