'Declaration
 
<SerializableAttribute()>
Public Class AnnPointObject 
   Inherits AnnObject
   Implements IAnnPictureObject, System.ICloneable, System.IDisposable, System.Runtime.Serialization.ISerializable

'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. AnnDrawable.Pen, AnnDrawable.Brush and Radius will be ignored. If ShowPicture is false; this object will draw an ellipse using AnnDrawable.Pen, AnnDrawable.Brush and Radius around CenterPoint.

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

For more information, refer to Using Pictures in Annotation Objects

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

This example adds a new point object to a container.
