复制屏幕的一部分 [英] Copy Part of the Screen

问题描述

嘿;)

遇到问题了.我想写一个小程序.我有2个屏幕.
我想复制左侧屏幕的一部分，并将其显示在我的程序的右侧屏幕上.到目前为止听起来很容易.我已经在C#中做到了.
好了，问题是，我想在游戏运行时复制零件.因此，简单的桌面截屏类将无法正常工作.如果游戏正在运行，它们只会返回黑色图像.我需要直接访问屏幕的后台缓冲区...
有人可以帮忙吗?
我自己可以使用DirectX 11进行操作，但这将是一个巨大的矫kill过正...
问候，
Shera

Hey ;)

Got a problem. I want to write a small program. I have 2 Screens.
I want to copy a part of the left screen and display it in my program on the right screen. Sounds pretty easy so far. I did it already in C#.
Well the problem is, that i want to copy the part while a game is running. So simple Desktop-Screenshot-Classes wont work. They just return a black image if game is running. I need a direct access to the backbuffer of the screen ...
Anyone can help ?
I could do it myself using DirectX 11, but that would be a huge overkill...

greets,
Shera

Take a look at that article[^] from Fade (Amit BS)[^].
