AnnVideoObject Class

Summary

Defines a video annotation object.

Syntax

C++

public class AnnVideoObject : Leadtools.Windows.Annotations.AnnImageObject, Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnImage, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnPicture, Leadtools.Windows.Annotations.IAnnRectangle

Public Class AnnVideoObject  
   Inherits Leadtools.Windows.Annotations.AnnImageObject 
   Implements Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnImage, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnPicture, Leadtools.Windows.Annotations.IAnnRectangle

public ref class AnnVideoObject : public Leadtools.Windows.Annotations.AnnImageObject, Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnImage, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnPicture, Leadtools.Windows.Annotations.IAnnRectangle

Remarks

The video annotation object is a scaled image that can be activated to play a video clip. The video file path is stored in the Uri property, so the video data itself is not stored in this object, only the physical path. In run mode, when this video object is clicked, the framework will try to locate and then play the video file stored in Uri. This object will use the default image of a video icon. To change this default image, change the Picture value.

The AnnVideoObject class inherits the AnnImageObject class and accesses the common Picture property mentioned above through this inheritance.

Example

This example creates a new video object at location 100, 200 and with dimensions of 400 x 600 and then adds it to a container.

Imports Leadtools.Windows.Annotations 
Imports Leadtools.Windows.Controls 
 
Private Sub AnnVideoObject_AnnVideoObject(ByVal container As AnnContainer, ByVal videoFileName As String) 
   Dim video As New AnnVideoObject() 
   video.Rect = New Rect(100, 200, 400, 600) 
   video.Uri = videoFileName 
   container.Children.Add(video) 
End Sub

using Leadtools.Windows.Controls; 
using Leadtools.Windows.Annotations; 
using Leadtools.Demos; 
using Leadtools.Help; 
 
private void AnnVideoObject_AnnVideoObject(AnnContainer container, string videoFileName) 
{ 
   AnnVideoObject video = new AnnVideoObject(); 
   video.Rect = new Rect(100, 200, 400, 600); 
   video.Uri = videoFileName; 
   container.Children.Add(video); 
}
