'Declaration
 
Public Class AnnAudioObject 
   Inherits AnnImageObject
   Implements IAnnHeader, IAnnImage, IAnnObject, IAnnPicture, IAnnRectangle

'Usage
 
Dim instance As AnnAudioObject

public sealed class AnnAudioObject : IAnnHeader, IAnnImage, IAnnObject, IAnnPicture, IAnnRectangle

function Leadtools.Windows.Annotations.AnnAudioObject()

public ref class AnnAudioObject : public AnnImageObject, IAnnHeader, IAnnImage, IAnnObject, IAnnPicture, IAnnRectangle

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

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

For more information about the audio annotation object refer to AnnAudioObject for WPF. For more information about the automated annotation audio object, refer to WPF Annotation Objects - Automated Features and WPF Automated Annotations - Audio Tab.
