Summary

Defines an annotation curve object.

Syntax

Objective-C

C++/CLI

Java

Python

public class AnnCurveObject : AnnPolylineObject

@interface LTAnnCurveObject : LTAnnPolylineObject<NSCoding, NSCopying>

public class AnnCurveObject extends AnnPolylineObject

public: 
   ref class AnnCurveObject : AnnPolylineObject

class AnnCurveObject(AnnPolylineObject):

Remarks

The curve object is a spline curve that contains a collection of Leadtools.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 AnnObject.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:

Example

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

using Leadtools.Annotations.Automation; 
using Leadtools.Annotations.Engine; 
using Leadtools.Codecs; 
using Leadtools.Annotations; 
using Leadtools.Annotations.WinForms; 
 
public void AnnCore_AnnCurveObject() 
{ 
   // assumes _automation is valid 
   double inch = 720.0; 
   // Add a red curve object 
   AnnCurveObject curveObj = new AnnCurveObject(); 
   // Set the points for curve 
   curveObj.Points.Add(LeadPointD.Create(1 * inch, 2 * inch)); 
   curveObj.Points.Add(LeadPointD.Create(2 * inch, 1 * inch)); 
   curveObj.Points.Add(LeadPointD.Create(3 * inch, 2 * inch)); 
   curveObj.Points.Add(LeadPointD.Create(4 * inch, 1 * inch)); 
   // Set the tension 
   curveObj.Tension = 0.8; 
   // Set the stroke 
   curveObj.Stroke = AnnStroke.Create(AnnSolidColorBrush.Create("Red"), LeadLengthD.Create(1)); 
   // Add the object to the automation container 
   _automation.Container.Children.Add(curveObj); 
}
