eSign document with multiple signatures

GroupDocs.Signature allows signing a 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 a 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);
}
