AnnCrossProductObject Object

Summary

Defines an annotation cross-product object.

Syntax
TypeScript
JavaScript
function lt.Annotations.Engine.AnnCrossProductObject 
	extends lt.Annotations.Engine.AnnPolyRulerObject 
	implements IAnnObjectCloneable 
class lt.Annotations.Engine.AnnCrossProductObject() 
	extends AnnPolyRulerObject 
	implements IAnnObjectCloneable 

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.

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 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:

Example

This example creates a cross product object and adds it to the automation container.

TypeScript
JavaScript
// assumes _automation is valid 
var inch = 720.0; 
// Add a red crossproduct object, from 1in 1in to 2in 2in 
var crossProductObj = new lt.Annotations.Engine.AnnCrossProductObject(); 
// Set the points for the first ruler 
crossProductObj.set_firstStartPoint(lt.LeadPointD.create(1 * inch, 1 * inch)); 
crossProductObj.set_firstEndPoint(lt.LeadPointD.create(2 * inch, 2 * inch)); 
// Set the points for the second ruler 
crossProductObj.set_secondStartPoint(lt.LeadPointD.create(2 * inch, 1 * inch)); 
crossProductObj.set_secondEndPoint(lt.LeadPointD.create(1 * inch, 2 * inch)); 
// Calculate the intersection point 
crossProductObj.updateIntersectionPoint(); 
// Set the stroke 
crossProductObj.set_stroke(lt.Annotations.Engine.AnnStroke.create(lt.Annotations.Engine.AnnSolidColorBrush.create("red"), lt.LeadLengthD.create(1))); 
// Add the object to the automation container 
this._automation.get_container().get_children().add(crossProductObj); 
// Select the object 
this._automation.selectObject(crossProductObj); 
// assumes _automation is valid 
const inch: number = 720.0; 
// Add a red crossproduct object, from 1in 1in to 2in 2in 
const crossProductObj: lt.Annotations.Engine.AnnCrossProductObject = new lt.Annotations.Engine.AnnCrossProductObject(); 
// Set the points for the first ruler 
crossProductObj.firstStartPoint = lt.LeadPointD.create(1 * inch, 1 * inch); 
crossProductObj.firstEndPoint = lt.LeadPointD.create(2 * inch, 2 * inch); 
// Set the points for the second ruler 
crossProductObj.secondStartPoint = lt.LeadPointD.create(2 * inch, 1 * inch); 
crossProductObj.secondEndPoint = lt.LeadPointD.create(1 * inch, 2 * inch); 
// Calculate the intersection point 
crossProductObj.updateIntersectionPoint(); 
// Set the stroke 
crossProductObj.stroke = lt.Annotations.Engine.AnnStroke.create(lt.Annotations.Engine.AnnSolidColorBrush.create("red"), lt.LeadLengthD.create(1)); 
// Add the object to the automation container 
this._automation.container.children.add(crossProductObj); 
// Select the object 
this._automation.selectObject(crossProductObj);
