AnnCrossProductObject Class

Summary

Defines an annotation cross product object.

Syntax

C++

[SerializableAttribute()] 
public class AnnCrossProductObject : Leadtools.Annotations.AnnObject, Leadtools.Annotations.IAnnRulerObject, System.ICloneable, System.IDisposable, System.Runtime.Serialization.ISerializable

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

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

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.

Example

This example creates a cross product object.

using Leadtools; 
using Leadtools.Annotations; 
using Leadtools.Codecs; 
using Leadtools.WinForms; 
 
private void AnnCrossProductObject_AnnCrossProductObject(AnnContainer container) 
{ 
   AnnCrossProductObject crossProduct = new AnnCrossProductObject(); 
   crossProduct.Pen = new AnnPen(Color.Red, new AnnLength(1, AnnUnit.Pixel)); 
   crossProduct.Font = new AnnFont("Arial", new AnnLength(10, AnnUnit.Point), FontStyle.Regular); 
   crossProduct.FirstStartPoint = new AnnPoint(5, 5, AnnUnit.Inch); 
   crossProduct.FirstEndPoint = new AnnPoint(10, 10, AnnUnit.Inch); 
   // make this cross product symmetrical 
   crossProduct.UpdateSecondPoints(); 
   // update the intersection point 
   crossProduct.UpdateIntersectionPoint(); 
   crossProduct.MeasurementUnit = AnnUnit.Inch; 
   crossProduct.TickMarksLength = new AnnLength(0.25F, AnnUnit.Inch); 
   crossProduct.ShowTickMarks = true; 
   crossProduct.GaugeLength = new AnnLength(1.0F, AnnUnit.Inch); 
   crossProduct.ShowGauge = true; 
   crossProduct.ShowLength = true; 
   crossProduct.Precision = 2; 
   container.Objects.Add(crossProduct); 
 
   // show the intersection point 
   MessageBox.Show(String.Format("Intersection point is at: {0}", crossProduct.IntersectionPoint)); 
}
