AnnPointObject Class

Show in webframe
Example 





Members 
Defines an annotation point object.
Object Model
Syntax
public class AnnPointObject : AnnObject, IAnnHeaderIAnnObjectIAnnPictureIAnnPoint  
'Declaration
 
Public Class AnnPointObject 
   Inherits AnnObject
   Implements IAnnHeaderIAnnObjectIAnnPictureIAnnPoint 
'Usage
 
Dim instance As AnnPointObject

            

            
public ref class AnnPointObject : public AnnObject, IAnnHeaderIAnnObjectIAnnPictureIAnnPoint  
Remarks
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.
