AnnPointObject Class

Summary

Defines an annotation point object.

Syntax

C++

public class AnnPointObject : Leadtools.Windows.Annotations.AnnObject, Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnPicture, Leadtools.Windows.Annotations.IAnnPoint

Public Class AnnPointObject  
   Inherits Leadtools.Windows.Annotations.AnnObject 
   Implements Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnPicture, Leadtools.Windows.Annotations.IAnnPoint

public ref class AnnPointObject : public Leadtools.Windows.Annotations.AnnObject, Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnPicture, Leadtools.Windows.Annotations.IAnnPoint

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.

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.

Example

This example adds a new point object to a container.
