public ref class AnnPointObject : public AnnObject, IAnnHeader, IAnnObject, IAnnPicture, IAnnPoint

'Declaration
 
Public Class AnnPointObject 
   Inherits AnnObject
   Implements IAnnHeader, IAnnObject, IAnnPicture, IAnnPoint

'Usage
 
Dim instance As AnnPointObject

The point object is a single point. This object works in two ways: If the value of ShowPicture is true; this object will draw the picture in Picture with CenterPoint as the center point. Stroke, StrokeBrush, Fill, FillBrush and Radius will be ignored. If ShowPicture is false; this object will draw an ellipse using Stroke, Fill and Radius around CenterPoint.

This class implements the IAnnPicture interface and accesses the IAnnPicture.Picture property that handles the picture associated with the annotation object.

For more information about the point annotation object refer to AnnPointObject for WPF. For more information about the automated point annotation object, refer to WPF Annotation Objects - Automated Features and WPF Automated Annotations - Point Tab.
