Note: |
This topic is for Document/Medical only. |
The Freehand Hot Spot annotation object (ANN_OBJECT_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. on the button triggers an AnnClicked event.
The points can be changed using the AnnGetPointX method, AnnGetPointY method and AnnSetPoints method.
