barCode.DpiY = 72;
barCode.Module = 2f;

//Specify the frame settings.
RectangleQRFrameOptions frameOpt = new RectangleQRFrameOptions() {
    FrameWidth = 4,
    FrameColor = System.Drawing.Color.DarkRed,
    Text = "Scan me",
    TextAlignment = QRFrameTextAlignment.Baseline,
    TextPosition = QRFrameTextPosition.Top,
