NORMALIZEDRECT

The NORMALIZEDRECT structure is used with the VMR filter in mixing operations to specify or retrieve the location of a video rectangle in composition space.

Syntax

typedef struct _NORMALIZEDRECT {
    float  left;
    float  top;
    float  right;
    float  bottom;
} NORMALIZEDRECT;
typedef struct _NORMALIZEDRECT *PNORMALIZEDRECT;

Members

left

Specifies left.

top

Specifies top.

right

Specifies right.

bottom

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.

Requirements

Requires Microsoft® Windows® XP.
