AnnCrossProductObject Class

Summary

Defines an annotation cross product object.

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.
