生活随笔 收集整理的這篇文章主要介紹了 java鼠标图片裁剪,如何用Java中的鼠标指针捕获屏幕图像 小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

How to capture screen image with mouse pointer on it in Java? In know that i can capture screen with Robot class, but it captures screen without mouse pointer on it, so this is not an solution for me.

解決方案

That's not directly possible, but you can use MouseInfo#getPointerInfo() to get information where the pointer is currently located.

int x = MouseInfo.getPointerInfo().getLocation().x;

int y = MouseInfo.getPointerInfo().getLocation().y;

After getting the screenshot as BufferedImage, you can place your own cursor image at exactly that location on the screenshot with help of Java 2D API.

Rectangle screen = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());

BufferedImage screenCapture = new Robot().createScreenCapture(screen);

Image cursor = ImageIO.read(new File("c:/cursor.gif"));

int x = MouseInfo.getPointerInfo().getLocation().x;

int y = MouseInfo.getPointerInfo().getLocation().y;

Graphics2D graphics2D = screenCapture.createGraphics();

graphics2D.drawImage(cursor, x, y, 16, 16, null); // cursor.gif is 16x16 size.

ImageIO.write(screenCapture, "GIF", new File("c:/capture.gif"));
