title: Generate barcode from text and convert it to base64
body: <p>Does someone knows a tool to generate barcode image (preferably code 39) from a string and converts it to base64 string, something to use like this:  </p>
  
  <pre><code>var text = "11220"; // text to convert
  var base64Str = textToBase64Barcode(text); // function to convert its input 
          // to an image formatted in a base64 string like : "data:image/jpeg;base64..."
  </code></pre>
  
  <p>?</p>
