Defines an annotation polyline object.
public class AnnPolylineObject : AnnObject
@interface LTAnnPolylineObject : LTAnnObject<NSCoding,NSCopying>
public class AnnPolylineObject extends AnnObject
ref class AnnPolylineObject : AnnObject
The polyline object is a simple polyline that contains a collection of Leadtools.LeadPointD points and a stroke
With the automated functions, on systems with mouse support, each line segment is formed with a mouse click, and the object is completed on a double-click.
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, 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 polyline object can be controlled using the following properties:
Each object can be transformed with the following methods:
The AnnPolylineObject class inherits a number of properties from the AnnObject class, providing support for font, stroke and fill characteristics. These properties are listed below:
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 AnnPolylineObject:
This example creates a polyline object and adds it to the automation container.
public void AnnCore_AnnPolylineObject()
// assumes _automation is valid
double inch = 720.0;
// Add a freehand hotspot object
AnnPolylineObject polyLineObj = new AnnPolylineObject();
// Set the points for the freehand hotspot
polyLineObj.Points.Add(LeadPointD.Create(1 * inch, 1 * inch));
polyLineObj.Points.Add(LeadPointD.Create(2 * inch, 2 * inch));
polyLineObj.Points.Add(LeadPointD.Create(1 * inch, 5 * inch));
polyLineObj.Points.Add(LeadPointD.Create(5 * inch, 5 * inch));
polyLineObj.Points.Add(LeadPointD.Create(4 * inch, 2 * inch));
polyLineObj.Points.Add(LeadPointD.Create(5 * inch, 1 * inch));
// Set the stroke
polyLineObj.Stroke = AnnStroke.Create(AnnSolidColorBrush.Create("Red"), LeadLengthD.Create(3));
// Set the fill
polyLineObj.Fill = AnnSolidColorBrush.Create("Green");
// Set the figure to closed
polyLineObj.IsClosed = true;
// Add the object to the automation container
