Summary

Defines an annotation point object.

Syntax
C#
VB
Java
Objective-C
C++
public class AnnPointObject : AnnObject 
Public Class AnnPointObject  
   Inherits AnnObject 
   Implements IAnnObjectCloneable  
@interface LTAnnPointObject : LTAnnObject<NSCoding,NSCopying> 
public class AnnPointObject extends AnnObject 
public: 
   ref class AnnPointObject : AnnObject 

Remarks

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

With the automated functions, in design mode, each point is formed with a click or tap event.

Programmatically, the boundaries and location of the point object can be controlled using the following properties:

Each object can be transformed with the following methods:

The AnnPointObject class inherits a number of properties from the AnnObject class, providing support for font, stroke and fill characteristics. These properties are listed below:

The name of the point object can be controlled using Labels property, inherited from the AnnObject class.

An object can be part of a group annotation object or part of a container object. It cannot be part of both a group and a container at the same time.

The following properties can also be used to programmatically set characteristics of an AnnPointObject:

Example

This example creates a point object and adds it to the automation container.

C#
using LeadtoolsExamples.Common; 
using Leadtools.Annotations.Automation; 
using Leadtools.Annotations.Engine; 
using Leadtools.Codecs; 
using Leadtools.Annotations.WinForms; 
 
public void AnnCore_AnnPointObject() 
{ 
   // assumes _automation is valid 
   double inch = 720.0; 
   // Add a point object 
   AnnPointObject pointObj = new AnnPointObject(); 
   // Set the point for the pointer 
   pointObj.CenterPoint = LeadPointD.Create(1 * inch, 1 * inch); 
   // Set the radius 
   pointObj.Radius = LeadLengthD.Create(75); 
   // Hide the picture 
   pointObj.ShowPicture = false; 
   // Add the object to the automation container 
   _automation.Container.Children.Add(pointObj); 
}
