用Java提取光标图像

public class CursorExtractor {

        // 读取屏幕截图
        Mat screenShot = Highgui.imread("screen_shot.png");

        // 获取光标图像的位置和大小
        Point cursorPosition = new Point(500, 300);
        int cursorSize = 32;
        Rect cursorRect = new Rect(cursorPosition.x - cursorSize / 2, cursorPosition.y - cursorSize / 2, cursorSize, cursorSize);

        // 提取光标图像
        Mat cursor = screenShot.submat(cursorRect);

        // 保存光标图像
        Highgui.imwrite("cursor.png", cursor);
