How can I display an image in the Applet?

Question

I have an image and I want to display it in the applet, The problem is the image wont display. Is there something wrong with my code?

Thanks...

Here\'s my co

Answer 1

aang = getImage(getDocumentBase(), getParameter("images.jpg"));

I suspect you are doing something wrong, and that should be just plain:

aang = getImage(getDocumentBase(), "images.jpg");

What is the content of HTML/applet element? What is the name of the image? Is the image in the same directory as the HTML?

Update 1

The 2nd (changed) line of code will try to load the images.jpg file in the same directory as the HTML.

Of course, you might need to add a MediaTracker to track the loading of the image, since the Applet.getImage() method returns immediately (now), but loads asynchronously (later).

Update 2

Try this exact experiment:

Save this source as ${path.to.current.code.and.image}/FirstAirBender.java .

/*


*/
import javax.swing.*;
import java.awt.*;
import java.net.URL;
import javax.imageio.ImageIO;

public class FirstAirBender extends JApplet {

    Image aang;

    public void init() {
        try {
            URL pic = new URL(getDocumentBase(), "images.jpg");
            aang = ImageIO.read(pic);
        } catch(Exception e) {
            // tell us if anything goes wrong!
            e.printStackTrace();
        }
    }

    public void paint(Graphics g) {
        super.paint(g);
        if (aang!=null) {
            g.drawImage(aang, 100, 100, this);
        }
    }
}

Then go to the prompt and compile the code then call applet viewer using the source name as argument.

C:\Path>javac FirstAirBender.java
C:\Path>appletviewer FirstAirBender.java
C:\Path>

You should see your image in the applet, painted at 100x100 from the top-left.
