Crossproduct Annotation Object

Note:

This topic is for Document/Medical only.

The cross-product annotation object (ANNOBJECT_CROSSPRODUCT) consists of two rulers intersecting at right angles. With the automated functions, the cross product is started on a mouse-down event and completed on a mouse-up event.

With low-level functions, the points must be defined by calling the AnnSetPoints method . The points are ordered as follows:
