title: opencv c and c++ interface conversion table
body: <p>i'l learning opencv with c++ and so i'm trying to use new c++ interface. but a lot of code i found on internet is based on old c interface.</p>
  
  <p>for example i fond a lot of algorithm based on</p>
  
  <pre><code>IplImage, cvCvtPixToPlane, cvThreshold
  </code></pre>
  
  <p>and i have to translate them in</p>
  
  <pre><code>cv::Mat, cv::threshold, ..
  </code></pre>
  
  <p>in <a href="http://opencv.willowgarage.com/documentation/cpp/introduction.html" rel="nofollow">here</a> (i think the official manual) i haven't find anything of really complete.</p>
  
  <p>and each time i have to google for get the right conversion in the new c++ interface.
  where can i find a conversion table?</p>
