Why can't I resize jpg images in the applet?

Question

I used this code to display images in an html page. One applet for one image. But out of the 8 images I loaded, 6 adjusted themselves to 320x240 automatically, 1 randomly jumps around to certain parts of the image every 250millisecs, and 1 just cuts the top left hand part of 320x240. How can .jpg files give 3 different situations? I tried using the resize() method in the code but it doesn't do anything! How can I size those .jpg images to the size I want?
/**This video stream applet loads a new image every 250ms
import java.applet.*;
import java.awt.*;
import java.net.*;
import java.io.*;
import java.awt.event.*;
public class Video extends Applet implements Runnable{
private Image img,buffer;
private Thread video = null;
private URL url;
private MediaTracker tracker;
public synchronized void init(){
tracker = new MediaTracker(this);
try{url = new URL(getCodeBase(),"Camera1.jpg");}
catch(MalformedURLException e){}
img = getImage(url);
tracker.addImage(img, 0);
buffer = createImage(320,240);
resize(320,240);
if(video!=null)return;
video = new Thread(this,"VideoStream");
video.start();
public synchronized void destroy(){
if(video!=null)video=null;
public void run(){
while(!Thread.interrupted()){
// Load new image.
try{tracker.waitForID(0);}
catch(InterruptedException e){}
// Draw new Image.
repaint();
// Remove old image & add new one.
tracker.removeImage(img,0);
img.flush();
tracker.addImage(img,0);
// Sleep
try{Thread.sleep(250);}
catch(InterruptedException e){}
public synchronized void update(Graphics g){
Graphics bufGraph = buffer.getGraphics();
bufGraph.drawImage(img,0,0,this);
paint(bufGraph);
g.drawImage(buffer,0,0,this);
public void paint(Graphics g){
g.drawImage(buffer,0,0,this);
Also how can I add more than 1 .jpg in an applet since the applet tag for html is
<applet code = Video.class width =... height = ...>
<param name = "buffer" value = "Camera1.jpg"> ...and I can only put
</applet> one file for "value
Thanks a lot for ur help!

Answer 1

you may try the function getScaledInstance(int,int,int) in Class Image.
the first and second parameters are the width and height you want,the third parameter is hints-flags to indicate the type of algorithm to use for image resampling.
