    XRBarCode barCode = new XRBarCode();

    // Set the bar code's type to Code 39.
    barCode.Symbology = new Code39Generator();

    // Adjust the bar code's main properties.
    barCode.Text = BarCodeText;
    barCode.Width = 400;
    barCode.Height = 100;

    // Adjust the properties specific to the bar code type.
    ((Code39Generator)barCode.Symbology).CalcCheckSum = false;
    ((Code39Generator)barCode.Symbology).WideNarrowRatio = 2.5F;

    return barCode;
