AnnPointObject Class

Summary

Defines an annotation point object.

Syntax

C++

[SerializableAttribute()] 
public class AnnPointObject : IAnnPictureObject, AnnObject

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

[SerializableAttribute()] 
public ref class AnnPointObject : public Leadtools.Annotations.AnnObject, Leadtools.Annotations.IAnnPictureObject, System.ICloneable, System.IDisposable, System.Runtime.Serialization.ISerializable

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. 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.

Example

This example adds a new point object to a container.

using Leadtools; 
using Leadtools.Annotations; 
using Leadtools.Codecs; 
using Leadtools.WinForms; 
 
private void AnnPointObject_AnnPointObject(RasterImageViewer viewer, AnnContainer container) 
{ 
   AnnPointObject point = new AnnPointObject(); 
   point.CenterPoint = new AnnPoint(100, 100, AnnUnit.Pixel); 
   point.ShowPicture = true; 
   // default picture, no need to change anything 
   container.Objects.Add(point); 
 
   viewer.Invalidate(point.InvalidRectangle); 
   MessageBox.Show("Picture"); 
 
   // show with a radius 
   point.Radius = new AnnLength(16, AnnUnit.Pixel); 
   point.Pen = new AnnPen(Color.Red, new AnnLength(1, AnnUnit.Pixel)); 
   point.ShowPicture = false; 
   viewer.Invalidate(point.InvalidRectangle); 
   MessageBox.Show("No picture"); 
}

Imports Leadtools 
Imports Leadtools.Annotations 
Imports Leadtools.Codecs 
Imports Leadtools.WinForms 
 
Private Sub AnnPointObject_AnnPointObject(ByVal viewer As RasterImageViewer, ByVal container As AnnContainer) 
   Dim point As AnnPointObject = New AnnPointObject() 
   point.CenterPoint = New AnnPoint(100, 100, AnnUnit.Pixel) 
   point.ShowPicture = True 
   ' default picture, no need to change anything 
   container.Objects.Add(point) 
 
   viewer.Invalidate(point.InvalidRectangle) 
   MessageBox.Show("Picture") 
 
   ' show with a radius 
   point.Radius = New AnnLength(16, AnnUnit.Pixel) 
   point.Pen = New AnnPen(Color.Red, New AnnLength(1, AnnUnit.Pixel)) 
   point.ShowPicture = False 
   viewer.Invalidate(point.InvalidRectangle) 
   MessageBox.Show("No picture") 
End Sub
