class	ArithmeticalDSS< TCoordinate, TInteger, adjacency >

Detailed Description

template<typename TCoordinate, typename TInteger = TCoordinate, unsigned short adjacency = 8>
class DGtal::ArithmeticalDSL< TCoordinate, TInteger, adjacency >

Aim: This class represents a naive (resp. standard) digital straight line (DSL), ie. the set of digital points \( (x,y) \in \mathbb{Z}^2 \) such that \( \mu \leq ax - by < \mu + \omega \) with \( a,b,\mu,\omega \in \mathbb{Z} \), \( \gcd(a,b) = 1 \) and \( \omega = \max(|a|,|b|) \) (resp. \( \omega = |a| + |b| \)). Note that any DSL such that \( \omega = \max(|a|,|b|) \) (resp. \( \omega = |a| + |b| \)) is simply 8-connected (resp. 4-connected).

[Reveilles, 1991 : [69]].

A naive DSL can be declared and constructed as follows:

#include "DGtal/arithmetic/geometry/curves/ArithmeticalDSL.h"
...
ArithmeticalDSL<DGtal::int32_t, DGtal::int64_t, 8> line( 17711, 28657, 1607895256 );
// equivalent to ArithmeticalDSL<DGtal::int32_t, DGtal::int64_t> line( 17711, 28657, 1607895256 );

See Digital straight lines and segments for further details.

This class is a model of CPointFunctor and of CConstBidirectionalRange.

In the standard case, it is enough to replace 8 by 4.

Template Parameters

TCoordinate	a model of integer for the DGtal point coordinates and the slope parameters.
TInteger	a model of integer for the intercepts and the remainders that represents a larger range of integers than TCoordinate.
adjacency	an unsigned integer equal to 8 (default) for naive DSL, and 4 for standard DSL.
