D3DDDIARG_VIEWPORTINFO structure

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

Syntax


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

Members

X

Width

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