_D3DDDIARG_VIEWPORTINFO structure

Description

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

Members

X [in]

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

Y [in]

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

Width [in]

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

Height [in]

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.
