◆ arVideoUtilFindAspectRatio()

AR_VIDEO_ASPECT_RATIO arVideoUtilFindAspectRatio	(	int	w,
		int	h
	)

Determine the approximate aspect ratio for a given image resolution.

A convenience method which makes it easy to determine the approximate aspect ratio of an image with the given resolution (expressed in pixel width and height). Returns a symbolic constant for the aspect ratio, which makes it easy to determine whether two different resolutions have the same aspect ratio. Assumes square pixels.

Parameters

w	Width in pixels
h	Height in pixels

Returns: If a matching commonly-used aspect ratio can be found, returns symbolic constant for that aspect ratio.
