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.
