title: Why ZXing.net doesn't decode EAN-13 barcodes, created by itself
body: <p>I'm trying to generate and scan EAN-13 barcode : </p>
  
  <pre><code>BarcodeReader barcodeReader = new BarcodeReader();
          BarcodeWriter barcodeWriter = new BarcodeWriter
          {
              Format = BarcodeFormat.EAN_13
          };
          barcodeWriter.Options.Height = 200;
          barcodeWriter.Options.Width = 200;
  
          barcodeReader.Options.PossibleFormats = new List&lt;BarcodeFormat&gt;();
          barcodeReader.Options.PossibleFormats.Add(BarcodeFormat.EAN_13);
          barcodeReader.Options.TryHarder = true;
  
  
          string content = "123123123123";
          Bitmap barcodeBitmap = barcodeWriter.Write(content);
          var res = barcodeReader.Decode((Bitmap)barcodeBitmap); //res == null
          Console.WriteLine(res.Text);
  </code></pre>
  
  <p>Why ZXing.net can't scan barcodes generated by itself?</p>
  
  <p>UPD: 
  I print barcode on A4 paper, scan it and crop by image editor like this :
  <a href="https://i.stack.imgur.com/NUPvV.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NUPvV.jpg" alt="barcode"></a></p>
  
  <p>ZXing can't scan this barcode too</p>
