D3DKMDT_GDISURFACEDATA structure (d3dkmdt.h)
The D3DKMDT_GDISURFACEDATA structure describes surfaces that are used by GDI hardware acceleration and the Desktop Window Manager (DWM).
Syntax
typedef struct _D3DKMDT_GDISURFACEDATA {
[in] UINT Width;
[in] UINT Height;
[in] D3DDDIFORMAT Format;
[in] D3DKMDT_GDISURFACETYPE Type;
[in] D3DKMDT_GDISURFACEFLAGS Flags;
[out] UINT Pitch;
} D3DKMDT_GDISURFACEDATA;
Members
[in] Width
The width of the surface, in pixels.
[in] Height
The height of the surface, in pixels.
[in] Format
A D3DDDIFORMAT-typed value that indicates the pixel format of the surface. The following formats are supported:
D3DDDIFMT_A8B8G8R8
D3DDDIFMT_X8B8G8R8
D3DDDIFMT_A8R8G8B8
D3DDDIFMT_X8R8G8B8
D3DDDIFMT_A8
The D3DDDIFMT_A8 format is used only for D3DKMDT_GDISURFACE_STAGING and D3DKMDT_GDISURFACE_STAGING_CPUVISIBLE staging surface types from the D3DKMDT_GDISURFACETYPE enumeration.
[in] Type
A D3DKMDT_GDISURFACETYPE-typed value that indicates the surface type.
[in] Flags
Reserved for future use. Must be zero.
[out] Pitch
The width of the surface, which includes padding, in bytes. The display miniport driver must return the pitch value for all allocations of D3DKMDT_GDISURFACETYPE type D3DKMDT_GDISURFACE_STAGING_CPUVISIBLE, D3DKMDT_GDISURFACE_EXISTINGSYSMEM, and D3DKMDT_GDISURFACE_TEXTURE_CROSSADAPTER.
Remarks
The D3DKMDT_GDISURFACEDATA structure is passed by the Microsoft DirectX graphics kernel subsystem in a call to the display miniport driver's DxgkDdiGetStandardAllocationDriverData function. This call generates a description of a surface that can be used for redirection by GDI hardware acceleration and the DWM.
