java打印屏幕两台显示器 [英] java print screen two monitors

问题描述

我正在尝试使用打印屏幕图像区域来获得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显示器吗？

I'm trying to use print screen image area to get 2 monitors, but only works for one monitor. Can you advise me how to get figure 2 monitors?

        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"));

推荐答案

结合每个屏幕的边界：

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);
