typedef std::vector<std::pair<int,result_t::value_t> > cass::pp311::ring_t

void pp311::fillRing	(	const result_t &	image,
		const int	rad,
		const int	x0,
		const int	y0,
		const int	nxx,
		ring_t &	ring
	)

private

fill the ring with the pixels that belong to a certain radius around a given center

Note: the ring that is passed to this function should already contain enough elements as it will not be refilled.

Parameters

image	the original image
rad	the radius for which the ring should be found
x0	the center in x
y0	the center in y
nxx	the number of columns of the original image
ring	the ring that will contain the result

Returns: the amount of pixels that belong to the radius

Parameters
