Hi Pavan,
what probably happens is that you're trying to display
an image which is not fully loaded at that time. Try
to modify your code to use MediaTracker class.
Here is an example:
import java.awt.*;
import java.awt.image.*;
public class Test extends Frame {
Image image;
public Test() {
image = Toolkit.getDefaultToolkit().getImage("duke2.gif");
MediaTracker tracker = new MediaTracker(this);
tracker.addImage(image, 1);
try {
tracker.waitForAll();
} catch (Exception e) {
image = null;
System.err.println("Can't load image");
}
setSize(200, 200);
setVisible(true);
}
public void paint(Graphics g0) {
if (image != null) {
g.drawImage(image, 50, 50, null);
}
}
public static void main(String argv[]) {
new Test();
}
}
Thank you,
Dmitri
