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>

/// </summary>
/// <returns></returns>

{
return CaptureWindow(User32.GetDesktopWindow());
}
/// <summary>
/// 指定窗口截图
/// </summary>
/// <param name="handle">窗口句柄. (在windows应用程序中, 从Handle属性获得)</param>
/// <returns></returns>
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, , , width, height, hdcSrc, , , GDI32.SRCCOPY);
GDI32.SelectObject(hdcDest, hOld);
GDI32.DeleteDC(hdcDest);
User32.ReleaseDC(handle, hdcSrc);
Image img = Image.FromHbitmap(hBitmap);
GDI32.DeleteObject(hBitmap);
return img;
}
