D3DDDIARG_VIEWPORTINFO structure (d3dumddi.h)

  • Article

The D3DDDIARG_VIEWPORTINFO structure describes the location and size of a view-clipping rectangle.

Syntax

typedef struct _D3DDDIARG_VIEWPORTINFO {
  [in] UINT X;
  [in] UINT Y;
  [in] UINT Width;
  [in] UINT Height;
} D3DDDIARG_VIEWPORTINFO;

Members

[in] X

The x coordinate, in screen coordinates, for the upper-left corner of the view-clipping rectangle.

[in] Y

The y coordinate, in screen coordinates, for the upper-left corner of the view-clipping rectangle.

[in] Width

The width, in screen coordinates, of the view-clipping rectangle where the application is rendering.

[in] Height

The height, in screen coordinates, of the view-clipping rectangle where the application is rendering.

Remarks

The user-mode display driver's SetViewport function should update the viewport portion of its internal rendering context with the location and size values that are specified in the D3DDDIARG_VIEWPORTINFO structure. The driver can use this information to perform guard band clipping.
