DXGI_DDI_ARG_BLT1 structure

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 {
  DXGI_DDI_HDEVICE       hDevice;
  DXGI_DDI_HRESOURCE     hDstResource;
  UINT                   DstSubresource;
  UINT                   DstLeft;
  UINT                   DstTop;
  UINT                   DstRight;
  UINT                   DstBottom;
  DXGI_DDI_HRESOURCE     hSrcResource;
  UINT                   SrcSubresource;
  UINT                   SrcLeft;
  UINT                   SrcTop;
  UINT                   SrcRight;
  UINT                   SrcBottom;
  DXGI_DDI_ARG_BLT_FLAGS Flags;
  DXGI_DDI_MODE_ROTATION Rotate;
} DXGI_DDI_ARG_BLT1;

Members

hDevice

[in] 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.

hDstResource

[in] A handle to the destination resource.

DstSubresource

[in] The index to the destination surface within the resource.

DstLeft

[in] The x-coordinate of the upper-left corner of the destination rectangle.

DstTop

[in] The y-coordinate of the upper-left corner of the destination rectangle.

DstRight

[in] The x-coordinate of the lower-right corner of the destination rectangle.

DstBottom

[in] The y-coordinate of the lower-right corner of the destination rectangle.

hSrcResource

[in] A handle to the source resource.

SrcSubresource

[in] The index to the source surface within the resource.

SrcLeft

[in] The x-coordinate of the upper-left corner of the source rectangle.

SrcTop

[in] The y-coordinate of the upper-left corner of the source rectangle.

SrcRight

[in] The x-coordinate of the lower-right corner of the source rectangle.

SrcBottom

[in] The y-coordinate of the lower-right corner of the destination rectangle.

Flags

[in] A DXGI_DDI_ARG_BLT_FLAGS structure that identifies the type of bitblt to perform.

Rotate

[in] 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.
