title: convert openCV image into PIL Image in Python (for use with Zbar library)
body: <p>I'm trying to use the Zbar library's QR code detection methods on images I extract with OpenCV's camera methods. Normally the QR code detection methods work with images (jpg, png, etc.) on my computer, but I guess the captured frames of OpenCV are different.<br>
  Is there a way of making the captured frame into a PIL Image?</p>
  
  <p>Thank you.</p>
  
  <pre><code>from PIL import Image
  import zbar
  import cv2.cv as cv
  
  capture = cv.CaptureFromCAM(1)
  imgSize = cv.GetSize(cv.QueryFrame(capture))
  img = cv.QueryFrame(capture)
  
  #SOMETHING GOES HERE TO TURN FRAME INTO IMAGE
  img = img.convert('L')
  width, height = img.size
  
  scanner = zbar.ImageScanner()
  scanner.parse_config('enable')
  zbar_img = zbar.Image(width, height, 'Y800', img.tostring())
  
  # scan the image for barcodes
  scanner.scan(zbar_img)
  
  for symbol in zbar_img:
      print symbol.data
  </code></pre>
