title: Detecting letters using pyocr(tesseract) on a grid
body: <p>I have successfully used pyocr with tesseract to detect text on this <a href="https://i.stack.imgur.com/R8OwI.png" rel="nofollow noreferrer">image</a></p>
  
  <p>Code:</p>
  
  <pre><code>from PIL import Image
  import sys
  
  import pyocr
  import pyocr.builders
  
  # Tools
  tools = pyocr.get_available_tools()
  if len(tools) == 0:
      print("No OCR tool found")
      sys.exit(1)
  tool = tools[0]
  print("Will use tool '%s'" % (tool.get_name()))
  
  # Language
  langs = tool.get_available_languages()
  lang = langs[0]
  print("Will use lang '%s'" % (lang))
  
  # Get text
  txt = tool.image_to_string(
      Image.open('1.jpg'),
      builder=pyocr.builders.TextBuilder()
  )
  
  print(txt)
  </code></pre>
  
  <p>Unfortunately when I try this <a href="https://i.stack.imgur.com/nJKc5.jpg" rel="nofollow noreferrer">image</a>, I dont get any result at all.
  My plan is to have an array such as (R, U, S, L)</p>
