eSign document with multiple signatures

GroupDocs.Signature allows to sign document with several signatures simultaneously and even apply signatures of different types to the same document. Doing this is as simple as:

This code snippet below demonstrates how to eSign PDF document with multiple signatures at the same time.

using (Signature signature = new Signature("sample.pdf"))
{
    // define several signature options of different types and settings
    TextSignOptions textOptions = new TextSignOptions("This is test message")
    {
        VerticalAlignment = VerticalAlignment.Top,
        HorizontalAlignment = HorizontalAlignment.Left
    };

    BarcodeSignOptions barcodeOptions = new BarcodeSignOptions("123456")
    {
        EncodeType = BarcodeTypes.Code128,
        Left = 100,
        Top = 100
    };
    QrCodeSignOptions qrcodeOptions = new QrCodeSignOptions("JohnSmith")
    {
        EncodeType = QrCodeTypes.QR,
        Left = 100,
        Top = 200
    };
    DigitalSignOptions digitalOptions = new DigitalSignOptions("certificate.pfx")
    {
        ImageFilePath = Constants.ImageHandwrite,
        VerticalAlignment = VerticalAlignment.Center,
        HorizontalAlignment = HorizontalAlignment.Center,
        Password = "1234567890"
    };
    // define list of signature options
    List<SignOptions> listOptions = new List<SignOptions>();
    listOptions.Add(textOptions);
    listOptions.Add(barcodeOptions);
    listOptions.Add(qrcodeOptions);
    listOptions.Add(digitalOptions);

    // sign document to file
    signature.Sign("signed.pdf", listOptions);
