学习图形学时做的大作业

计算机图形学之应用之屏保编程源码及其程序。-Application of computer graphics programming screen saver source code and its procedures.

在中小型电力行业系统中，曲线的要求比较严格，虽然网络上面各种曲线控件非常多，但是很多只能提供一段时间的曲线显示或者历史若干个点的显示。比如在一个普通的小型水电站系统中我们会牵涉到许多的点（可能甚至达到400到500多个），一般的电站运行人员或者管理者希望能够对这类点的历史运行状况进行还原（即能够将历史运行的各个点状况进行还原），曲线就是非常重要的一个环节了 -SMEs in the power industry system, the curve of more stringent requirements, While the Network Control curve above all very, but many can only provide for a period of time curve or historical point of a number of shows. For example, in an ordinary small hydropower system, which will involve many of the points (which may even reach 4-500 many), Utility general operating personnel or managers hope to be able to point to the history of such operations conducted reduction (that is, to history Operation of each of the state reduction), the curve is a very important link in the

用GDI函数抓屏 如果我们不太在意抓屏的效率，并且我们想要的只是一个屏幕快照的话，可以考虑使用GDI方式。这种抓屏机制是以“桌面也是一个窗口，桌面也有一个窗口句柄（HWND）”这个简单的常识为基础的，如果我们得到了桌面的设备上下文（DC），就可以利用blit（复制）它的内容到我们创建的DC中。我们可以用GetDeskWindow（）得到桌面的窗口句柄，从句柄得到DC也是很容易的 -GDI function with screenshots screenshots if we do not care about efficiency, and we want only a snapshot of the screen, you can consider using GDI mode. This mechanism is based on the screenshots Desktop is also a window, the desktop also has a window handle (HWND) This simple knowledge-based, if we get the desktop device context (DC), can be used on the blit (copy) its contents that we created in DC. We can use GetDeskWindow () get desktop window handle from the handle to get DC is also very easy
