Need urgent help ..save BMP image

Question

I have a BMP image .I m extracting its pixels (using PixelGrabber)and formatting those values as per requirements.
Now,I have to create an image using this pixels array again.
Image img;
img = createImage(new MemoryImageSource(iw,ih,pixels,0,iw)) ;This is creating an[b] image "img" of type Image.
Now,I have to save this image as BMP.
for this I am using
ImageIO.write(img,"BMP",new File("a.bmp"));The problem is this[b] write method require an image of type Buffered Image.
I am not able to typecast an object of type Image into BufferedImage.
BufferedImage is subclass of Image class..
I just hope i m making sense..
Please help me..
Is there any other way too to save an BMP image created by createImage()

Thnx a lot for help I used a method u told me ...
here is the code i hve:
import java.io.*;
import java.awt.*;
import javax.swing.*;
import javax.imageio.*;
import java.awt.image.*;
import java.awt.image.PixelGrabber;
import javax.imageio.ImageIO;
public class RecreateImage2
        public static void main(String args[])
                ImageFrame frame = new ImageFrame();
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setVisible(true);
class ImageFrame extends JFrame
        public ImageFrame()
             Toolkit kit=Toolkit.getDefaultToolkit();
          Dimension screenSize=kit.getScreenSize();
          int screenHeight=screenSize.height;
          int screenWidth=screenSize.width;
          setSize(screenWidth/2,screenHeight/2);
          setLocation(screenWidth/4,screenHeight/4);
          setTitle("Centered Frame");
          ImagePanel1 panel=new ImagePanel1();
             add(panel);                                     
class ImagePanel1 extends JPanel
        Image img;
        public ImagePanel1()
                try
               Image image;
               Dimension d;
               int iw,ih;
                        image = ImageIO.read(new File("bug_apple.bmp"));
               iw = image.getWidth(null);
               ih = image.getHeight(null);
                        int pixels[] = new int[ih*iw];
               PixelGrabber pg = new    PixelGrabber(image,0,0,iw,ih,pixels,0,iw);
                        pg.grabPixels();
                        img = createImage(new MemoryImageSource(iw,ih,pixels,0,iw));      
               BufferedImage bi = new BufferedImage(iw,ih,BufferedImage.TYPE_INT_ARGB)
               Graphics2D g2d = bi.createGraphics();
                  g2d.drawImage(img, 0, 0, null);
                  g2d.dispose();
               img=bi;
               ImageIO.write(img,"BMP",new File("a.bmp")) ;          
                catch(InterruptedException e)
                catch(IOException e)
                        e.printStackTrace();
}Its giving error ...saying
cannot find method write(java.awt.Image,java.lang.String,java.io.File)But If i use Method
ImageIO.write((BufferedImage)img,"BMP",new File("a.bmp")) ;It saves the Image as "a.bmp" but preview of image is not available...
Please help me..I really dono whr the proplem is..
