有没有办法使用Java截取屏幕截图并将其保存为某种图像？ [英] Is there a way to take a screenshot using Java and save it to some sort of image?

问题描述

简单如标题所述：您是否可以仅使用Java命令截取屏幕并保存？或者，我是否需要使用特定于操作系统的程序来截取屏幕截图，然后将其从剪贴板中取出？

Simple as the title states: Can you use only Java commands to take a screenshot and save it? Or, do I need to use an OS specific program to take the screenshot and then grab it off the clipboard?

推荐答案

相信它或不，您实际上可以使用 java.awt.Robot 以创建包含从屏幕读取的像素的图像。然后，您可以将该图像写入磁盘上的文件。

Believe it or not, you can actually use java.awt.Robot to "create an image containing pixels read from the screen." You can then write that image to a file on disk.

我刚尝试过，整个过程最终结果如下：

I just tried it, and the whole thing ends up like:

Rectangle screenRect = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
BufferedImage capture = new Robot().createScreenCapture(screenRect);
ImageIO.write(capture, "bmp", new File(args[0]));

注意：这只会捕获主监视器。有关多显示器支持，请参见 GraphicsConfiguration 。

NOTE: This will only capture the primary monitor. See GraphicsConfiguration for multi-monitor support.
