AnnPolylineObject Object

The polyline object is a simple polyline that contains a collection of 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:

• Bounds
• Points

Each object can be transformed with the following methods:

• Scale
• Translate
• Rotate

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:

• Fill
• Stroke
• Font
• SupportsFill
• SupportsStroke
• SupportsFont

The name of the polyline 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.

The following properties can also be used to programmatically set characteristics of an AnnPolylineObject:

• IsClosed
• FillRule
• Hyperlink
• IsLocked
• Password
• IsVisible

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

example: function SiteLibrary_DefaultPage$example() {
   // assumes _automation is valid
   var inch = 720.0;
   // Add a freehand hotspot object
   var polyLineObj = new lt.Annotations.Core.AnnPolylineObject();
   // Set the points for the freehand hotspot
   polyLineObj.get_points().add(lt.LeadPointD.create(1 * inch, 1 * inch));
   polyLineObj.get_points().add(lt.LeadPointD.create(2 * inch, 2 * inch));
   polyLineObj.get_points().add(lt.LeadPointD.create(1 * inch, 5 * inch));
   polyLineObj.get_points().add(lt.LeadPointD.create(5 * inch, 5 * inch));
   polyLineObj.get_points().add(lt.LeadPointD.create(4 * inch, 2 * inch));
   polyLineObj.get_points().add(lt.LeadPointD.create(5 * inch, 1 * inch));
   // Set the stroke
   polyLineObj.set_stroke(lt.Annotations.Core.AnnStroke.create(lt.Annotations.Core.AnnSolidColorBrush.create("red"), lt.LeadLengthD.create(3)));
   // Set the fill
   polyLineObj.set_fill(lt.Annotations.Core.AnnSolidColorBrush.create("green"));
   // Set the figure to closed
   polyLineObj.set_isClosed(true);
   // Add the object to the automation container
   this._automation.get_container().get_children().add(polyLineObj);
   // Select the object
   this._automation.selectObject(polyLineObj);
