AnnAudioObject Class

Summary

Defines an audio annotation object.

Syntax

C++

[SerializableAttribute()] 
public class AnnAudioObject : AnnImageObject

  
<SerializableAttribute()> 
Public Class AnnAudioObject  
   Inherits Leadtools.Annotations.AnnImageObject 
   Implements Leadtools.Annotations.IAnnPictureObject, System.ICloneable, System.IDisposable, System.Runtime.Serialization.ISerializable

[SerializableAttribute()] 
public ref class AnnAudioObject : public Leadtools.Annotations.AnnImageObject, Leadtools.Annotations.IAnnPictureObject, System.ICloneable, System.IDisposable, System.Runtime.Serialization.ISerializable

Remarks

The audio annotation object is a scaled image that can be activated to play an audio (WAV) clip. The WAV file path is stored in the FileName 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 FileName. 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 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 (Deprecated). For more information about the automated annotation audio object, refer to Annotation Objects - Automated Features (Deprecated) and Automated Annotations - Audio Tab (Deprecated).

Example

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

using Leadtools; 
using Leadtools.Annotations; 
using Leadtools.Codecs; 
using Leadtools.WinForms; 
 
private void AnnAudioObject_AnnAudioObject(AnnContainer container, string waveFileName) 
{ 
   AnnAudioObject audio = new AnnAudioObject(); 
   audio.Bounds = new AnnRectangle(100, 200, 400, 600, AnnUnit.Pixel); 
   audio.FileName = waveFileName; 
   container.Objects.Add(audio); 
   // play the audio to test it 
   if ((audio.CanPlay)) 
      audio.Play(); 
}

Imports Leadtools 
Imports Leadtools.Annotations 
Imports Leadtools.Codecs 
Imports Leadtools.WinForms 
 
Private Sub AnnAudioObject_AnnAudioObject(ByVal container As AnnContainer, ByVal waveFileName As String) 
   Dim audio As AnnAudioObject = New AnnAudioObject() 
   audio.Bounds = New AnnRectangle(100, 200, 400, 600, AnnUnit.Pixel) 
   audio.FileName = waveFileName 
   container.Objects.Add(audio) 
   ' play the audio to test it 
   If (audio.CanPlay) Then 
      audio.Play() 
   End If 
End Sub
