write an existing image to disk

Hi,
I want to save an image to a drive. I loaded it with getToolkit().getImage(..). I MUST use an Image because I want to scale it before saving. Can you help me please, I tried ImageIO from the jdk 1.4 but I find only a solution for BufferedImage. This I can't scale like
Image img;
img = img.getScaledInstance(400, 271, Image.SCALE_SMOOTH);
this does not work:
File f = new File("name.jpg");
BufferedImage bimage = new BufferedImage(..);
bimage = bimage.getScaledInstance(400, 271, Image.SCALE_SMOOTH); // <- problem
ImageIO.write(bImage, "jpg", f);

Thanks!!!

PLEEEEEEAAAAAAAAAAAAASSSSEEEEE.......

the solution:
Image medImage = getToolkit().getImage(..);
medImage = medImage.getScaledInstance(400, 277, Image.SCALE_SMOOTH);
BufferedImage medBImage = new BufferedImage(400, 277, BufferedImage.TYPE_INT_RGB);
add medImage to a mediatracker!
medBImage.createGraphics().drawImage(medImage,0,0,null);
File f = new File("image.jpg");
try
{
ImageIO.write(medBImage, "jpg", f);
}
catch(Exception e)
{
System.out.println(e);
}
Easy or ?
