Hi Ed,
Maybe this could help you.
There should be better ways of doing that but at least it works. ;-)

public void grayscale() {
BufferedImage bi = getSourceImage(); // getBufferedImage();
int width = bi.getWidth() ;
int height = bi.getHeight() ;
int type = bi.getType() ;
BufferedImage grayBi = new BufferedImage(width, height,
BufferedImage.TYPE_BYTE_GRAY);
Graphics g = grayBi.getGraphics();
g.drawImage(bi, 0, 0, null);
bi = null ;
// put grayscale image back to the same image type
BufferedImage bf = new BufferedImage(width, height,type);
bf.getGraphics().drawImage(grayBi, 0, 0, null);
setSourceImage(bf,true);
// free resources allocated
g.dispose();
g = null ;
grayBi = null ;
}
