title: python - OpenCV mat::convertTo in python
body: <p>Is there any function in the OpenCV python wrapper that does the same thing as Mat's convertTo method in OpenCV 2? </p>
  
  <p>I basically want to call this function in python</p>
  
  <pre><code>out.convertTo( out, CV_32F, 1.0/255, 0 );
  </code></pre>
  
  <p>where out is a grayscale image.</p>
  
  <p>I have already made use of cv.ConvertScale by keeping my dst argument as type CV_32FC1, but I am trying to keep my python code as cv2 conformant as possible. Any clues?</p>
