[Java-gnome-developer] Pixbuf

[Douglaz <do...@gm...>]

Hello everyone!

    I'm writing a small application which is collecting the image from a few
ip cameras and showing them in a grid.
    In order to do so, I have a few threads collecting the bytes, creating
new Pixbuf object with those bytes, and updating a DataColumnPixbuf.

    I noticed an increase of the memmory usage as time goes by.
    Should I by using some method in order to free those unused Pixbuf
objects?
    Or is there a way to update these existing objects?

Best regards,
Douglas

ps.: In the following tiny test you can see the memmory increase (checking
the system resources):

package camera;

import javax.swing.JOptionPane;
import org.gnome.gdk.Pixbuf;
import org.gnome.gtk.Gtk;

public class Main {

    public Main() {
        super();
        Loader loader = new Loader();
        loader.start();
        JOptionPane.showMessageDialog(null, "Press ok to exit the program");
    }

    public static void main(String[] arsg) {
        Gtk.init(new String[] {});
        new Main();
        System.exit(0);
    }

    protected class Loader extends Thread {

        public void run() {
            while (true) {
                try {
                    Pixbuf p1 = new Pixbuf("camera.jpg");
                    Pixbuf p2 = new Pixbuf("camera.jpg");
                    Pixbuf p3 = new Pixbuf("camera.jpg");
                    sleep(200);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }

    }

}
