template<typename xy_locator , typename SrcP >

void terry::sampler::details::getPixelsPointers	(	const xy_locator &	loc,
		const point2< std::ptrdiff_t > &	p0,
		const int &	windowWidth,
		const int &	imageWidth,
		const EParamFilterOutOfImage &	outOfImageProcess,
		std::vector< SrcP > &	src
	)

Get pixels around a particular position.

Parameters:

[in]	loc	locator which points to a pixel
[in]	pt0	x,y position of loc
[in]	windowWidth	the region inside which we search our pixels
[out]	ptN	pixel value to retrieve

it's to use with (B,C) filter number of points need to be even

----------------- | A | B | C | D | ----------------- ^..... loc is pointing to D point
