在Windows上快速捕获桌面屏幕

Question

I want to capture the desktop screen image on Windows.

I know about the CreateCompatibleDC and CreateCompatibleBitmap... functions in C++ but it they are very slow. I need a more rapid method that does a screen capture suitable for real-time updates. In Linux I could use Xlib functions, for example. Are there any similar high-speed or system-level screencap functions for Windows?

Answer 1

For Windows 8 (and later) there is native API: Desktop Duplication API

For Windows 7 (and earlier) you may consider using a mirror driver. For example, the DFMirage driver
