Remarks

The AnnMediaObject derives from AnnHotspotObject object and is designed to hold the URL to a media file (audio or video).

The AnnMediaObject object will draw the picture if the owner container is in design mode. If the container is in run mode, the AnnMediaObject object will not draw the picture, instead, the automation framework will create a media control and play the URL into it.

With the automated functions, in design mode, the rectangle contains a scaled image. The user clicks / taps and drags to specify the rectangle in the current window.

using Leadtools.Annotations.Engine; 
using Leadtools.Codecs; 
using Leadtools.Annotations.WinForms; 
 
public void AnnCore_AnnMediaObject() 
{ 
   // assumes _automation is valid 
   double inch = 720.0; 
   // Add a Media object 
   AnnMediaObject mediaObj = new AnnMediaObject(); 
   // Set the points for the MediaObject 
   mediaObj.Points.Add(LeadPointD.Create(1 * inch, 1 * inch)); 
   mediaObj.Points.Add(LeadPointD.Create(2 * inch, 1 * inch)); 
   mediaObj.Points.Add(LeadPointD.Create(2 * inch, 2 * inch)); 
   mediaObj.Points.Add(LeadPointD.Create(1 * inch, 2 * inch)); 
 
   // create the AnnMedia with a source to the media to play 
   AnnMedia media = new AnnMedia(); 
   //Replace the source with your video file to be played on click 
   media.Source1 = "ms-appx:///Videos/TestVideo.avi"; 
   mediaObj.Media = media; 
   // Add the object to the automation container 
   _automation.Container.Children.Add(mediaObj); 
}
