AnnProtractorObject Object

Summary

Defines an annotation protractor object.

Syntax

JavaScript Syntax
function lt.Annotations.Engine.AnnProtractorObject 
	extends lt.Annotations.Engine.AnnPolyRulerObject 
	implements IAnnObjectCloneable 

TypeScript Syntax
class lt.Annotations.Engine.AnnProtractorObject() 
	extends AnnPolyRulerObject 
	implements IAnnObjectCloneable 

Remarks

The protractor annotation object consists of two rulers joined at a point to create an angle. The center point is CenterPoint, the first line ends at FirstPoint and the second point ends at SecondPoint.

With the automated functions, the first line of the protractor is started on a click or tap event and completed on a second click or tap event. The second line is completed on a third click or tap event.

With the automated functions, on systems with touch support, the first line segment starts with the first tap and hold. Each successive tap and hold for 1.5 seconds results in a new line segment. The object is completed by the user removing the finger from the device.

Programmatically, the boundaries and location of the protractor object can be controlled using the following properties: Each object can be transformed with the following methods: The AnnProtractorObject 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 protractor object can be controlled using Labels property, inherited from the AnnObject class. 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. Since the annotation protractor 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: The following properties can also be used to programmatically set characteristics of an AnnProtractorObject:

Example

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

JavaScript Example
// assumes _automation is valid 
var inch = 720.0; 
// Add a protractor object 
var protractorObj = new lt.Annotations.Engine.AnnProtractorObject(); 
// Set the points for the protractor 
protractorObj.set_firstPoint(lt.LeadPointD.create(5 * inch, 1 * inch)); 
protractorObj.set_centerPoint(lt.LeadPointD.create(1 * inch, 3 * inch)); 
protractorObj.set_secondPoint(lt.LeadPointD.create(5 * inch, 5 * inch)); 
// Set the radius 
protractorObj.set_arcRadius(lt.LeadLengthD.create(350)); 
// Add the object to the automation container 
this._automation.get_container().get_children().add(protractorObj); 
// Select the object 
this._automation.selectObject(protractorObj);
