For instance from fluorescent images to "normal" images. (FiSH to "normal" images):
works like this: newpixelvalue = 255 - pixelvalue

This works for single layer images as well as RGB images.


Code:
   /**
    * Inverts image, single layer
    * @author   Ramon Fincken, http://www.ramonfincken.com/permalink/topic243.html
    * @param fullpath
    * @param write_to_png
    */
   public void invert(String fullpath, String write_to_png)
   {
       ImagePlus img = IJ.openImage(fullpath);
       ImageProcessor IP = img.getProcessor();
      
       IP.invert();
       img.setProcessor(IP);

       IJ.save(img, write_to_png);
   }
