Here is the code of FreehandRoiBis :

import ij.*;
import ij.gui.*;

public class FreehandRoiBis extends FreehandRoi {

     public FreehandRoiBis(int x, int y, ImagePlus imp) {
         super(x, y, imp);
     }

     public void grow(int ox, int oy) {
         super.grow(ox, oy);
     }

}

Hope that will help you &;)

>(e.g. for roi.drawPixels(myImageProcessor);  I'm getting a compiler error
>(drawPixels() in ij.gui.Roi cannot be applied to
>(ij.process.ImageProcessor)). Thanks a lot!
