How to: Create a Sound Annotation

The following code snippet creates a sound annotation and embeds a WAV audio file:

C#

using DevExpress.Docs.Pdf;
using System.Drawing;

using (PdfDocument pdfDocument =
    new PdfDocument(File.OpenRead(@"Document.pdf")))
{
    // Create a sound annotation
    SoundAnnotation annotation =
                new SoundAnnotation(
                        new RectangleF(50, 420, 20, 20));

    annotation.Title = "John Smith";
    annotation.Content = "Voice note";
    annotation.IconName = SoundAnnotationIconName.Mic;

    // Load sound data from a WAV file
    Sound sound = new Sound();
    sound.SamplingRate = 44100;
    sound.SoundChannels = 2;
    sound.BitsPerSample = 16;
    sound.Encoding = SoundEncoding.Raw;
    sound.Data = File.ReadAllBytes(Path.Combine(Directory.GetCurrentDirectory(), "VoiceNote.wav"));
    annotation.Sound = sound;

    //  Add the annotation to the first page of the PDF document
    pdfDocument.Pages[0].Annotations.Add(annotation);

    pdfDocument.Save(File.OpenWrite(@"DocumentWithAnnotation.pdf"));
}

VB.NET

Import DevExpress.Docs.Pdf
Import System.Drawing

Using pdfDocument As New PdfDocument(File.OpenRead("Document.pdf"))
    ' Create a sound annotation
    Dim annotation As New SoundAnnotation(New RectangleF(50, 420, 20, 20))

    annotation.Title = "John Smith"
    annotation.Content = "Voice note"
    annotation.IconName = SoundAnnotationIconName.Mic

    ' Load sound data from a WAV file
    Dim sound As New Sound()
    sound.SamplingRate = 44100
    sound.SoundChannels = 2
    sound.BitsPerSample = 16
    sound.Encoding = SoundEncoding.Raw
    sound.Data = File.ReadAllBytes(Path.Combine(Directory.GetCurrentDirectory(), "VoiceNote.wav"))
    annotation.Sound = sound

    ' Add the annotation to the first page of the PDF document
    pdfDocument.Pages(0).Annotations.Add(annotation)

    pdfDocument.Save(File.OpenWrite("DocumentWithAnnotation.pdf"))
