screencapture using java applet

Question

Trying to figure out how can I create a screencapture applet like screenr.com does .. i want to be able to produce a similar result.

I found that there are ways to capture screenshot.. from a signed applet.. but can't seem to find any information on video capture.

thoughts?

Answer 1

Use java.awt.Robot to take screenshot .... This is simple Java code snippet .. you can break the video in individual frames and then use the capture code...

import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import java.io.File;

import javax.imageio.ImageIO;

public class FilePrinter 
{
public static void main(String[] args) {
    try {
        Robot robot = new Robot();
        Rectangle captureSize = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
        BufferedImage bufferedImage = robot.createScreenCapture(captureSize);
        ImageIO.write(bufferedImage, "png", new File("c:/temp/test.png"));
    }
    catch(Exception e) {
        System.err.println("Someone call a doctor!");
    }

}
}

Hope this will be useful ...

Update: Refer to the following link for getting individual frames. The guy is using 'Java Media Framework' to do that ...
