DirectX Graphics

DirectDraw,微软Direct X的一员,是基于COM架构下的2D API,例如DirectDraw的Blt()用于表面间整体图像或是部分图像的移动。

DirectDraw渐被Direct3D所取代,DirectShow的VMR-7 是以 DirectDraw 7 建造,因为使用DirectDraw 7 控制graphic card,所以称为VMR-7. VMR-9 则是基于 Direct3D 9. DirectX 8.0发表时,Direct3D与DirectDraw编程接口合并并改名为DirectX Graphics

DirectDraw DirectX Graphics

DirectDraw is a deprecated API that used to be a part of Microsoft's DirectX API. DirectDraw is used to accelerate rendering of graphics in applications. DirectDraw also allows applications to run fullscreen or embedded in a window such as most other MS Windows applications. DirectDraw uses hardware acceleration if it is available on the client's computer. DirectDraw allows direct access to video memory, hardware overlays, hardware blitters, and page flipping. Its video memory manager can manipulate video memory with ease, taking full advantage of the blitting and color decompression capabilities of different types of display adapters.
