title: iText DataMatrix barcode resolution and quality
body: <p>I'm trying to insert Data Matrix barcodes in a PDF using iText. This is kind of working, but the image quality is not good enough. Is it somehow possible to increase the image size and resolution?</p>
  
  <p>Example of my output: <a href="http://imgur.com/jdsEelv" rel="nofollow">http://imgur.com/jdsEelv</a></p>
  
  <pre><code>BarcodeDatamatrix dm = new BarcodeDatamatrix();
  dm.generate("1234567890");
  Image img = dm.createImage();
  cell = new PdfPCell(img, false);
  </code></pre>
