AnnCrossProductObject Class

Summary

Defines an annotation cross product object.

Syntax

C++

public class AnnCrossProductObject : Leadtools.Windows.Annotations.AnnObject, Leadtools.Windows.Annotations.IAnnCrossProduct, Leadtools.Windows.Annotations.IAnnFont, Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnRuler

Public Class AnnCrossProductObject  
   Inherits Leadtools.Windows.Annotations.AnnObject 
   Implements Leadtools.Windows.Annotations.IAnnCrossProduct, Leadtools.Windows.Annotations.IAnnFont, Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnRuler

public ref class AnnCrossProductObject : public Leadtools.Windows.Annotations.AnnObject, Leadtools.Windows.Annotations.IAnnCrossProduct, Leadtools.Windows.Annotations.IAnnFont, Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnRuler

Remarks

The cross-product annotation object consists of two rulers intersecting at right angles. The intersection point of a cross product object updates dynamically and can be obtained through the IntersectionPoint property.

For more information about the CrossProduct annotation object refer to AnnCrossProductObject for WPF. For more information about the automated CrossProduct annotation object, refer to WPF Annotation Objects - Automated Features.
