如何在C＃中使用Zxing安排Qr代码的定位

Question

如何为标签打印安排二维码的位置？？我已经尝试过此代码。如何在标签中间获取二维码？

        Encoding m_encoding = Encoding.GetEncoding("ISO-8859-1");
        byte[] dataFromFile = System.IO.File.ReadAllBytes(op1.FileName);
        string txt = m_encoding.GetString(dataFromFile);
        int tt = txt.Length;

        BarcodeWriter writer = new BarcodeWriter
        {
            Format = BarcodeFormat.QR_CODE,
            Options = new EncodingOptions
            {
                Width = 50,
                Height = 50
               // Margin = 1

            }
