Example 86 with GraphicsEnvironment

use of java.awt.GraphicsEnvironment in project karaf by apache.

the class ScreenshotDumpProvider method createDump.

/**
	 * {@inheritDoc}
	 */
public void createDump(DumpDestination destination) throws Exception {
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    // get all graphic devices attached to computer
    GraphicsDevice[] gs = ge.getScreenDevices();
    // create dump entry for each device  
    for (int i = 0; i < gs.length; i++) {
        DisplayMode mode = gs[i].getDisplayMode();
        Rectangle bounds = new Rectangle(0, 0, mode.getWidth(), mode.getHeight());
        BufferedImage screenshot = new Robot(gs[i]).createScreenCapture(bounds);
        // to attach your entry to destination you have to execute this line
        OutputStream outputStream = destination.add("screenshot/display_" + i + ".png");
        ImageIO.write(screenshot, "PNG", outputStream);
        outputStream.close();
    }
