Questions tagged [directdraw]

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.
