How to Double Image Size

Use the following code to scale an image into double its original size:

import java.applet.*;
import java.awt.*;
import java.net.*;
public class ScaleImage extends Applet
{
    Image img;
    public void init()
    {
        try
        {
            img = getImage (new URL(getDocumentBase(),flo.jpg));
        }catch (MalformedURLException e)
       {
       	 System.out.println(URL not valid:+e);
        }
    }
    public void paint (Graphics g)
    {
        g.drawImage
(img,0,0,img.getWidth(null)*2,img.getHeight(null)*2,this);
    }
}
/*<applet CODE =ScaleImage   WIDTH =400 HEIGHT = 400>
</applet>*/
