Syntax

typedef struct _NORMALIZEDRECT {
  float  left;
  float  top;
  float  right;
  float  bottom;

typedef struct _NORMALIZEDRECT *PNORMALIZEDRECT;

Remarks

This structure is used in methods involving "composition space," which refers to the visible video rectangle, as well as the "offscreen" space necessary to contain rectangles from secondary streams. See Using the Video Mixing Renderer for more information.
