• Call Sign method of Signature class instance and pass signatureoptions and PresentationSaveOptions  object to it.

Following example demonstrates how to save signed Presentation document with different output type

{
    // create QRCode option with predefined QRCode text
    QrCodeSignOptions signOptions = new QrCodeSignOptions("JohnSmith")
    {
        // setup QRCode encoding type
        EncodeType = QRCodeTypes.QR,
        // set signature position
        Left = 100,
        Top = 100
    };
    PresentationSaveOptions saveOptions = new PresentationSaveOptions()
    {
        FileFormat = PresentationSaveFileFormat.Tiff,
        OverwriteExistingFiles = true
    };
    // sign document to file
    signature.Sign("SignedPPsx", signOptions, saveOptions);
}
