        if (image.generateBufferedImage()) {

            int width = image.getWidth();
            int height = image.getHeight();

            for (int h = 0; h < height; h++) {
                for (int w = 0; w < width; w++) {
                    image.getImage().setRGB(w, h, ImagingUtils.convertToGrayscale(image.getImage().getRGB(w, h)));
                }
