Summary

Gets the logical origin of this AnnObject.

Syntax

C++

public virtual Point Origin {get;}

Public Overridable ReadOnly Property Origin As Point

public: 
virtual property Point Origin { 
   Point get(); 
}

Property Value

The logical origin of this AnnObject.

Remarks

This method returns the logical origin of this AnnObject. This value is calculated by returning the origin of the DefiningGeometry value. You can use this origin to Rotate or Scale this object around itself. For more information, refer to Low-Level Coordinate System for WPF Annotations.

Example

Silverlight C#

Silverlight VB
