public class AnnCrossProductObject : AnnObject, IAnnCrossProduct, IAnnFont, IAnnHeader, IAnnObject, IAnnRuler

'Declaration
 
Public Class AnnCrossProductObject 
   Inherits AnnObject
   Implements IAnnCrossProduct, IAnnFont, IAnnHeader, IAnnObject, IAnnRuler

'Usage
 
Dim instance As AnnCrossProductObject

public ref class AnnCrossProductObject : public AnnObject, IAnnCrossProduct, IAnnFont, IAnnHeader, IAnnObject, IAnnRuler

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.

This example creates a cross product object.
