Hi folks!
What's the standard way to erase an ROI drawn on an image? I had been using:
   ip.resetRoi();
   imp.updateAndDraw();
But this fails to erase the Roi sice I've updated to ImageJ 1.34s and Java 1.4.1
I am now using the kludge below:
        void eraseRoi(){
          Roi r = null;
          try{imp.setRoi(r);}
          catch(Exception e){};
          imp.updateAndDraw();
          }

thanks, Bill O'Connell
