title: What is the max possible value of magnitude in polar system in OpenCV?
body: <p>In OpenCV I'm using cartToPolar function and I want to know the max possible value of calculated magnitude. Can it be greater than 255? I found something about calculation in the <a href="http://docs.opencv.org/2.4/doc/tutorials/imgproc/imgtrans/hough_lines/hough_lines.html" rel="nofollow noreferrer" title="documentation">documentation</a> about Hough Line Transform, but I still do not know the max value. I need this to calculate histograms, to devide the ranges for right buckets.</p>
  
  <p>Best regards,</p>
