java打印屏幕两台显示器

我正在尝试使用打印屏幕图像区域来获取2台显示器，但仅适用于一台显示器。您能建议我如何获得图2的显示器吗？

        Robot robot = new Robot();
        Rectangle screenRect = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
        BufferedImage capture = new Robot().createScreenCapture(screenRect);
        ImageIO.write(capture, "bmp", new File("printscreen.bmp"));

最佳答案

合并每个屏幕的边界:

Rectangle screenRect = new Rectangle(0, 0, 0, 0);
for (GraphicsDevice gd : GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices()) {
    screenRect = screenRect.union(gd.getDefaultConfiguration().getBounds());
}
BufferedImage capture = new Robot().createScreenCapture(screenRect);
