DirectDraw Structures (SDK) (Windows CE 5.0)
The following topics contain information about the following structures used with DirectDraw.
| Programming element | Description |
|---|---|
| DDALPHABLTFX | This structure passed details about blit operations to the IDirectDrawSurface5::AlphaBlt method. |
| DDBLTFX | This structure passes raster operations, effects, and override information to the IDirectDrawSurface5::Blt method. |
| DDCAPS | This structure represents the capabilities of the hardware exposed through the DirectDraw object. |
| DDCOLORCONTROL | This structure defines the color controls associated with a DirectDrawVideoPort object, an overlay surface, or a primary surface. |
| DDCOLORKEY | This structure describes a source color key, destination color key, or color space. |
| DDOVERLAYFX | This structure passes override information to the IDirectDrawSurface5::UpdateOverlay method. |
| DDPIXELFORMAT | This structure describes the pixel format of a DirectDrawSurface object for the IDirectDrawSurface5::GetPixelFormat method. |
| DDSCAPS | This structure defines the capabilities of a DirectDrawSurface object. |
| DDSCAPS2 | This structure defines the capabilities of a DirectDrawSurface object. |
| DDSCAPSEX | This structure contains the extended surface capabilities as defined by the application. |
| DDSURFACEDESC | This structure contains a description of a surface. This structure is passed to the IDirectDraw2::CreateSurface method. |
| DDSURFACEDESC2 | This structure contains a description of a surface. This structure is used to pass surface parameters to the IDirectDraw4::CreateSurface and IDirectDrawSurface5::SetSurfaceDesc methods. |
| DDVIDEOPORTBANDWIDTH | This structure describes the bandwidth characteristics of an overlay surface when used with a particular video port and pixel format configuration. |
| DDVIDEOPORTCAPS | This structure describes the capabilities and alignment restrictions of a video port. |
| DDVIDEOPORTCONNECT | This structure describes a video port connection. |
| DDVIDEOPORTDESC | This structure describes a video-port object to be created. |
| DDVIDEOPORTINFO | This structure describes the transfer of video data to a surface. |
| DDVIDEOPORTSTATUS | This structure describes the status of a video-port object. |
**Note **The memory for all DirectX structures should be initialized to zero before use. In addition, all structures that contain a dwSize member should set the member to the size of the structure, in bytes, before use.
DDCAPS ddcaps; // Cannot use this yet.
ZeroMemory(&ddcaps, sizeof(DDCAPS));
ddcaps.dwSize = sizeof(DDCAPS);
// Now the structure can be used.
