Hi Guy,

most ImageProcessor commands work on rectangular Rois.

You can either use the IJ.run method on the ImagePlus (which is the same
as when doing it via the GUI)
   IJ.run(imp, "Fill");
or make sure the ImageProcessor has a valid snapshot before filling and then
   ip.fill();
   ip.reset(ip.getMask());
