Namespace:	avl

Shrinks an image by a natural factor along each axis.

Syntax

void avl::ShrinkImageNTimes
(
	const avl::Image& inImage,
	atl::Optional<const avl::Box&> inRoi,
	int inNX,
	const atl::Optional<int>& inNY,
	avl::Image& outImage
)

Parameters

Name	Type	Range	Default	Description
inImage	const Image&			Input image
inRoi	Optional<const Box&>		NIL	Range of pixels to be processed
inNX	int	1 -	2
inNY	const Optional<int>&	1 -	NIL
outImage	Image&			Output image

Description

The operation shrinks the inImage reducing its dimensions by a natural factor.

Examples

ShrinkImageNTimes performed on the sample image with inNX = 2, inNY = 2.
