Problem using PixelGrabber ( cannot resolve symbol ) - newbie

Question

Hi All,
I have a problem with my short program because the compiler write this (jdk1.4) :
img.java:17: cannot resolve symbol
symbol : constructor PixelGrabber (java.awt.Image,int,int,int,int,int[],int)
location: class java.awt.image.PixelGrabber
PixelGrabber pg = new PixelGrabber(image,0,0,image.getWidth(this
),image.getHeight(this),pixels,0);
^
1 error
... And I wrote that in my code :
( all is OK, the bug is only when I uncomment the line where the PixelGrabber object
is needed in my program ).
Thanks if you have any idea of solution to solve this problem or a doc,
( I don't find the answer to my problem in http://java.sun.com/j2se/1.4/docs/api/java/awt/image/PixelGrabber.html ),
import java.awt.*;
import java.awt.image.*;
import java.applet.*;
import java.awt.image.PixelGrabber;
public class img extends Applet {
Image image;
int pixels[];
public void init() {
image = getImage(getDocumentBase(), "rouge.jpg");
pixels = new int[image.getWidth(this) * image.getHeight(this)];
PixelGrabber pg = new PixelGrabber(image,0,0,image.getWidth(this),image.getHeight(this),pixels,0);
     pg.grabPixels();
public void paint(Graphics g) {
          String s = Integer.toString(pixels[5], 16);
          g.drawString(s, 50, 50);

Hi,
PixelGrabber needs one more parameter scansize (width).
change this line;
PixelGrabber pg = new PixelGrabber(image,0,0,image.getWidth(this),image.getHeight(this),pixels,0);
to:
PixelGrabber pg = new PixelGrabber(image,0,0,image.getWidth(this),image.getHeight(this),pixels,0, image.getWidth(this)
);
