C#外挂QQ找茬辅助源码，早期开发

这是一款几年前开发的工具，当年作为一民IT纯屌，为了当年自己心目中的一位女神熬夜开发完成。女神使用后找茬等级瞬间从眼明手快升级为三只眼。。。每次看到这个就会想起那段屌丝与女神的回忆。今天特地把代码更新了一下，支持最新版的《大家来找茬》。下面上运行的截图，源码在本文最后：（对不起了，与我对战的那位玩家）

这个工具的主要运行流程很简单：游戏截图-》比较图片-》标记图片不同点
记得当时处理程序截图和比较图片的时候比较麻烦，下面是截图的处理类ScreenCapture：

    /// <summary>
    /// 提供全屏和指定窗口的截图 以及保存为文件的类
    /// </summary>
    public class ScreenCapture
    {
        /// <summary>
        /// 全屏截图
        /// </summary>
        public Image CaptureScreen()
        {
            return CaptureWindow(User32.GetDesktopWindow());
        }
        /// <summary>
        /// 指定窗口截图
        /// </summary>
        /// 窗口句柄. (在windows应用程序中, 从Handle属性获得)
        public Image CaptureWindow(IntPtr handle)
        {
            IntPtr hdcSrc = User32.GetWindowDC(handle);
            User32.RECT windowRect = new User32.RECT();
            User32.GetWindowRect(handle, ref windowRect);
            int width = windowRect.right – windowRect.left;
            int height = windowRect.bottom – windowRect.top;
            IntPtr hdcDest = GDI32.CreateCompatibleDC(hdcSrc);
            IntPtr hBitmap = GDI32.CreateCompatibleBitmap(hdcSrc, width, height);
            IntPtr hOld = GDI32.SelectObject(hdcDest, hBitmap);
            GDI32.BitBlt(hdcDest, 0, 0, width, height, hdcSrc, 0, 0, GDI32.SRCCOPY);
            GDI32.SelectObject(hdcDest, hOld);
            GDI32.DeleteDC(hdcDest);
            User32.ReleaseDC(handle, hdcSrc);
            Image img = Image.FromHbitmap(hBitmap);
            GDI32.DeleteObject(hBitmap);
