function lt.Annotations.Engine.AnnImageObject 
	extends lt.Annotations.Engine.AnnRectangleObject 
	implements IAnnObjectCloneable 

TypeScript Syntax
class lt.Annotations.Engine.AnnImageObject() 
	extends AnnRectangleObject 
	implements IAnnObjectCloneable 

Remarks

The AnnImageObject is a raster image defined by a bounding rectangle. This object does not support stroke or fill.

For more information, refer to Using Pictures in Annotation Objects.

Programmatically, the boundaries and location of the image object can be controlled using the following properties: Each object can be transformed with the following methods: The AnnImageObject 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 image 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 AnnImageObject:

Example

This example creates an image object and adds it to the automation container.

JavaScript Example
// assumes _automation is valid 
var inch = 720.0; 
// Add an image object 
var imageObj = new lt.Annotations.Engine.AnnImageObject(); 
// Set the points for the the image 
imageObj.get_points().add(lt.LeadPointD.create(1 * inch, 1 * inch)); 
imageObj.get_points().add(lt.LeadPointD.create(2 * inch, 1 * inch)); 
imageObj.get_points().add(lt.LeadPointD.create(2 * inch, 2 * inch)); 
imageObj.get_points().add(lt.LeadPointD.create(1 * inch, 2 * inch)); 
// Set the picture 
var picture = new lt.Annotations.Engine.AnnPicture("http://demo.leadtools.com/images/png/pngimage.png"); 
imageObj.set_picture(picture); 
// Add the object to the automation container 
this._automation.get_container().get_children().add(imageObj); 
// Select the object 
this._automation.selectObject(imageObj); 
 
// Hook to rendering engine loadPicture event to render the container immediately after resources get loaded 
var automation = this._automation; 
automation.get_manager().renderingEngine.add_loadPicture(function(sender, e) { 
  automation.invalidate(lt.LeadRectD.empty); 
 });
