Hi Andrew,

sorry, quite a late response; maybe you have found it in the  
meanwhile anyhow.

ImageStack.getProcessor creates a new ImageProcessor each time; any  
information written to the previous ImageProcessor gets lost with it.  
So you need:

      ImageProcessor ip = iplus2.getStack().getProcessor
(image.getCurrentSlice());

ant then ip.setFont, ip.setColor, ip.drawString.
