Thread: Create image Jpeg from an object of Image class.

I am working on a project on Steganography. I've succesfully encripted the source image with the text to be hidden, but i am unable to create an output image/encripted Jpeg from that object.
How to create an image file (Jpeg) from an object of Image class? please reply asap.

 
img2= createImage(new MemoryImageSource(iw,ih,pixels,0,iw));
	     BufferedImage image = toBufferedImage(img2);
	    save(image, "jpg");
 
 private static BufferedImage toBufferedImage(Image src) {
	        int w = src.getWidth(null);
	        int h = src.getHeight(null);
	        int type = BufferedImage.TYPE_USHORT_565_RGB;  // other options
	        BufferedImage dest = new BufferedImage(w, h, type);
	        Graphics2D g2 = dest.createGraphics();
	        g2.drawImage(src, 0, 0, null);
	        g2.dispose();
	        return dest;
	    }
 
	  private static void save(BufferedImage image, String ext) {
	        String fileName = "savingAnImage";
	        File file = new File(fileName + "." + ext);
	        try {
	            ImageIO.write(image, ext, file);  // ignore returned boolean
	        } catch(IOException e) {
	            System.out.println("Write error for " + file.getPath() +
	                               ": " + e.getMessage());
	        }
	    }
