    * @param source
    * @param write_to_png
    * @param width_factor
    * @param height_factor
    */
   public void resize_by(String source, String write_to_png, double width_factor, double height_factor)
   {
      ImagePlus imp1 = IJ.openImage(source);
      ImageProcessor ip=imp1.getProcessor();
      
      int new_width = (int)(ip.getWidth() * width_factor); 
      int new_height = (int)(ip.getHeight() * height_factor);
      
      ip = ip.resize(new_width, new_height);
      
      imp1.setProcessor(ip);
      WindowManager.setTempCurrentImage(imp1);
      IJ.saveAs("PNG", write_to_png);
