title: c# OCR can't recognize digits (tesseract 2)
body: <p>I'm trying to extract digits from the following: <a href="https://i.stack.imgur.com/r76ab.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/r76ab.png" alt="" /></a></p>
  
  <p>It fails, I get a <strong>~</strong> in return. I'm using google's tesseract 2, using C# (open source c# wrapper) and now I'm wondering, is this image too crappy to be used for OCR?</p>
  <p>Because imho the digits are straight clear.</p>
  <p>Do you have any other OCR engine in mind that would nail this down?</p>
  <p><strong>EDIT</strong></p>
  <p>I've also tried with <strong>Asprise OCR</strong> (<a href="http://asprise.com/product/ocr/selector.php" rel="nofollow noreferrer">http://asprise.com/product/ocr/selector.php</a>) but it fails to parse the image too...</p>
