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, *PNORMALIZEDRECT;

Members

left

The left corner of the normalized rectangle.

top

The top corner of the normalized rectangle.

right

The right corner of the normalized rectangle.

bottom

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.
