DXGI_DDI_ARG_BLT1 structure (dxgiddi.h)
Describes the parameters of a bit-block transfer (bitblt) that include specifications for a source rectangle. Used by Windows Display Driver Model (WDDM) 1.2 and later user-mode display drivers.
Syntax
typedef struct DXGI_DDI_ARG_BLT1 {
[in] DXGI_DDI_HDEVICE hDevice;
[in] DXGI_DDI_HRESOURCE hDstResource;
[in] UINT DstSubresource;
[in] UINT DstLeft;
[in] UINT DstTop;
[in] UINT DstRight;
[in] UINT DstBottom;
[in] DXGI_DDI_HRESOURCE hSrcResource;
[in] UINT SrcSubresource;
[in] UINT SrcLeft;
[in] UINT SrcTop;
[in] UINT SrcRight;
[in] UINT SrcBottom;
[in] DXGI_DDI_ARG_BLT_FLAGS Flags;
[in] DXGI_DDI_MODE_ROTATION Rotate;
} DXGI_DDI_ARG_BLT1;
Members
[in] hDevice
A handle to the display device (graphics context) on which the driver performs the bitblt. The Direct3D runtime passes this handle to the driver in the hDrvDevice member of the D3D10DDIARG_CREATEDEVICE structure when the runtime calls the driver's CreateDevice(D3D10) function to create the display device.
[in] hDstResource
A handle to the destination resource.
[in] DstSubresource
The index to the destination surface within the resource.
[in] DstLeft
The x-coordinate of the upper-left corner of the destination rectangle.
[in] DstTop
The y-coordinate of the upper-left corner of the destination rectangle.
[in] DstRight
The x-coordinate of the lower-right corner of the destination rectangle.
[in] DstBottom
The y-coordinate of the lower-right corner of the destination rectangle.
[in] hSrcResource
A handle to the source resource.
[in] SrcSubresource
The index to the source surface within the resource.
[in] SrcLeft
The x-coordinate of the upper-left corner of the source rectangle.
[in] SrcTop
The y-coordinate of the upper-left corner of the source rectangle.
[in] SrcRight
The x-coordinate of the lower-right corner of the source rectangle.
[in] SrcBottom
The y-coordinate of the lower-right corner of the destination rectangle.
[in] Flags
A DXGI_DDI_ARG_BLT_FLAGS structure that identifies the type of bitblt to perform.
[in] Rotate
A value of type DXGI_DDI_MODE_ROTATION that identifies the orientation of the display mode.
Remarks
The source rectangle specified by the members SrcLeft, SrcTop, SrcRight, and SrcBottom is typically a dirty subrectangle.
