function Leadtools.Annotations.Core.AnnCrossProductObject()

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.

With the automated functions, the cross-product is started on a drag started event and completed on a drag completed event.

Programmatically, the points that define this cross-product are contained in the FirstStartPoint, FirstEndPoint, SecondStartPoint, SecondEndPoint and IntersectionPoint properties.

Programmatically, the boundaries and location of the cross-product object can be controlled using the following properties:

Each object can be transformed with the following methods:

The AnnCrossProductObject class inherits a number of properties from the AnnObject class, providing support for font, stroke and fill characteristics. These properties are listed below:

The name of the cross-product object can be controlled using AnnObject.Labels property, inherited from the AnnObject class.

Since the cross-product object consists of two rulers, it has certain ruler characteristics pertaining to the length, tick marks and gauge. The following properties may be used to customize these ruler characteristics and determine what exactly is displayed when the cross-product object is drawn:

An object can be part of a group annotation object or part of a container object. It cannot be part of both a group and a container at the same time.

The following properties can also be used to programmatically set characteristics of an AnnCrossProductObject:
