void avl::SurfaceNormalsImage
(
	const avl::Surface& inSurface,
	atl::Optional<const avl::Region&> inRoi,
	const float inScale,
	avl::Image& outNormalsImage,
	atl::Optional<avl::Region&> outComputedRegion = atl::NIL
)

Parameters

	Name	Type	Range	Default	Description
	inSurface	const Surface&
	inRoi	Optional<const Region&>		NIL	Range of pixels to be processed
	inScale	const float	0.0 -	1.0f
	outNormalsImage	Image&
	outComputedRegion	Optional<Region&>		NIL
