AnnCurveObject Object


Defines an annotation curve object.


JavaScript Syntax
function lt.Annotations.Engine.AnnCurveObject 
	extends lt.Annotations.Engine.AnnPolylineObject 
	implements IAnnObjectCloneable 

TypeScript Syntax
class lt.Annotations.Engine.AnnCurveObject() 
	extends AnnPolylineObject 
	implements IAnnObjectCloneable 


The curve object is a spline curve that contains a collection of LeadPointD points, a Tension value and an AnnStroke.

Programmatically, the boundaries and location of the curve object can be controlled using the following properties: Each object can be transformed with the following methods: The AnnCurveObject 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 curve object can be controlled using Labels property, inherited from the AnnObject class. The boundaries and location of the curve object can be controlled using the following properties: 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 AnnCurveObject:


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

JavaScript Example
// assumes _automation is valid 
var inch = 720.0; 
// Add a red curve object 
var curveObj = new lt.Annotations.Engine.AnnCurveObject(); 
// Set the points for curve 
curveObj.get_points().add(lt.LeadPointD.create(1 * inch, 2 * inch)); 
curveObj.get_points().add(lt.LeadPointD.create(2 * inch, 1 * inch)); 
curveObj.get_points().add(lt.LeadPointD.create(3 * inch, 2 * inch)); 
curveObj.get_points().add(lt.LeadPointD.create(4 * inch, 1 * inch)); 
// Set the tension 
// Set the stroke 
curveObj.set_stroke(lt.Annotations.Engine.AnnStroke.create(lt.Annotations.Engine.AnnSolidColorBrush.create("red"), lt.LeadLengthD.create(1))); 
// Add the object to the automation container 
// Select the object
