title: OpenCv: second cvPutText not executetd
body: <p>I am using <code>cvPutText</code> in a loop and it is working fine (printing some data connected to different contours near each contour). the thing is, when trying to use another <code>cvPutText</code> in or before the loop (for example, printing frame number in the upper left corner of the image) only the first <code>cvPutText</code> is executed and printed. the second is ignored.</p>
  
  <p>the code looks like that:</p>
  
  <pre><code>char text[80];
  </code></pre>
  
  <p>in every loop:</p>
  
  <pre><code>char nam[] = "id : ";
  char na[] = "  area : ";
  char ka[] = "\n cNr : ";
  sprintf(text,"%s%d%s%d%s%d", nam, (*obListIter)-&gt;id, ka, contNumber, na ,area);
  CvFont font;
  cvInitFont(&amp;font, CV_FONT_HERSHEY_SIMPLEX, 0.4, 0.4, 0, 1, 8);
  cvPutText(cv_obj_rgb, text, cvPoint(boxPoints[4].x, boxPoints[4].y), &amp;font, cvScalar(255, 255, 255, 0));
  </code></pre>
  
  <p>the other <code>cvPutText</code> looks exactly the same, only with a different font (font2), chars and text. </p>
  
  <p>Can anybody help? I wasted already a couple of days because of that and I really need this feature to analyse the performance of my kalman filter and to finally finish my bachelor thesis.</p>
