Public bug reported:
The built in Java screen grabber
(java.awt.Robot.createScreenCapture(...)) does not work correctly with
unity-2d. When attempting to create a screen capture for the whole
screen only the dash and menu bars are captured - everything else is
black. This only affects unity-2d not unity or KDE.
Simple test case:
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.File;
import javax.imageio.ImageIO;
public class ScreenGrab {
public static void main(String[] args) {
try {
Rectangle grabRect = new
Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
Robot robot = new Robot();
BufferedImage capture = robot.createScreenCapture(grabRect);
ImageIO.write(capture, "PNG", new File("java-screen-shot.png"));
} catch (Exception e) {
e.printStackTrace();
}
}
}
