AnnFreehandHotspotObject Object

JavaScript

function Leadtools.Annotations.Core.AnnFreehandHotspotObject()

The freehand hot spot annotation object is designed to work as a scaled picture drawn inside a collection of points that create a sequence of joined lines. The freehand hot spot object will draw the picture if the owner container is in design mode. If the container is in run mode, the freehand hot spot object will not draw the picture.

In run mode, the object is transparent, but the mouse pointer changes to a hand when it is over the object. You can change the points of a freehand object using the Points collection property.

Programmatically, the boundaries and location of the freehand hotspot object can be controlled using the following properties:

Each object can be transformed with the following methods:

The AnnFreehandHotspotObject 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 freehand hotspot 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 AnnFreehandHotspotObject:

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

JavaScript

example: function SiteLibrary_DefaultPage$example() {
   // assumes _automation is valid
   // Create a new instance of AnnResources if the container does not already have one
   var resources = this._automation.get_container().get_resources();
   if (resources == null) {
      resources = new lt.Annotations.Core.AnnResources();
      this._automation.get_container().set_resources(resources);
   }
   // Get the images collection
   var imagesResources = resources.get_images();
   // Add our picture to it
   imagesResources.add(new lt.Annotations.Core.AnnPicture("Resources/Objects/Hotspot.png"));
   var pictureIndex = imagesResources.length - 1;

   var inch = 720.0;
   // Add a freehand hotspot object
   var hotspotObj = new lt.Annotations.Core.AnnFreehandHotspotObject();
   // Set the points for the freehand hotspot
   hotspotObj.get_points().add(lt.LeadPointD.create(1 * inch, 1 * inch));
   hotspotObj.get_points().add(lt.LeadPointD.create(2 * inch, 2 * inch));
   hotspotObj.get_points().add(lt.LeadPointD.create(1 * inch, 5 * inch));
   hotspotObj.get_points().add(lt.LeadPointD.create(5 * inch, 5 * inch));
   hotspotObj.get_points().add(lt.LeadPointD.create(4 * inch, 2 * inch));
   hotspotObj.get_points().add(lt.LeadPointD.create(5 * inch, 1 * inch));
   // Set the picture
   hotspotObj.set_defaultPicture(pictureIndex);
   // Set the hyperlink
   hotspotObj.set_hyperlink("https://www.leadtools.com");
   // Add the object to the automation container
   this._automation.get_container().get_children().add(hotspotObj);
   // Select the object
   this._automation.selectObject(hotspotObj);
