Something like this should work:

     ImageProcessor ip = imp.getProcessor();
     ip.drawString("Some text", 20, 20);
     imp.updateAndDraw();

where imp is the ImagePlus object corresponding to the FFT image. You
will probably also need to use other ImageProcessor methods such as
setColor() and setFont().
