using (Signature signature = new Signature("sample.pdf"))
{
    BarcodeSignOptions options = new BarcodeSignOptions("JohnSmith")
    {
        // setup Barcode encoding type
        EncodeType = BarcodeTypes.Code128,
        // set signature position
        Left = 100,
        Top = 100
    };
    signature.Sign("SampleSigned.pdf", options);
}
