NORMALIZEDRECT Structure

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

Syntax

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

Members

left

Specifies the left corner of the normalized rectangle.

top

Specifies the top corner of the normalized rectangle.

right

Specifies the right corner of the normalized rectangle.

bottom

Specifies the bottom corner of the normalized rectangle.

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.
