是GDI函数BitBlt和StretchBlt函数硬件加速的Win32？ [英] Are the GDI functions BitBlt and StretchBlt hardware accelerated in Win32?

问题描述

我似乎无法通过搜索得到一个明确的答案。是Win32的块传输操作的硬件加速（GDI，而不是GDI +）。我不知道这些功能如何与显卡驱动接口。是否有任何函数调用来验证这个功能，怎么样？GetCaps？为特定的图形设备（WIN32图形设备），看看是否这些功能的接收硬件加速？

I can't seem to get a definite answer to this via searching. Are the Win32 blitting operations hardware accelerated (GDI, not GDI+). I don't know how these functions interface with the graphics driver. Is there any function call to verify this functionality, like ?GetCaps? for a specific graphics device (win32 graphics device) to see if these functions are receiving hardware acceleration?

推荐答案

据的这个，GDI只是加快了Windows 7的硬件起。
这的名单如何指定哪些操作都不会被硬件加速。列入名单的BitBlt 和 StretchBlt ，所以是他们的硬件加速，但你需要有配套制度它，你需要启用它。

According to this, GDI is only hardware accelerated on windows 7 onwards. This lists how to specify which operations are to be hardware accelerated. included in the list is BitBlt and StretchBlt, so yes they are hardware accelerated, but you need to have a system supporting it, and you need to enable it.
