Detailed Description

template<typename TCoordinate, typename TInteger = TCoordinate>
class DGtal::StandardDSS4< TCoordinate, TInteger >

Aim: This class represents a standard digital straight segment (DSS), ie. the sequence of simply 4-connected digital points contained in a standard digital straight line (DSL) between two points of it. This class is an alias of ArithmeticalDSS.

A 4-connected DSS can be declared and constructed as follows:

  // Construct a standard DSS
  StandardDSS4<Integer> segment( 5, 8,                   //slope
                                 Point(0,0), Point(8,5), //ending points 
                                 Point(0,0), Point(8,5), //upper points
                                 Point(4,1), Point(4,1)  //lower points
                                 );

This requires the following include:

#include "DGtal/geometry/curves/ArithmeticalDSS.h"

See the documentation of NaiveDSS8 for a longer example and see Digital straight lines and segments for further details.

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.

This class is a model of CPointFunctor and of CConstBidirectionalRange.

Constructor & Destructor Documentation

◆ StandardDSS4() [1/6]

template<typename TCoordinate, typename TInteger = TCoordinate>

DGtal::StandardDSS4< TCoordinate, TInteger >::StandardDSS4	(	const Coordinate &	aA,
		const Coordinate &	aB,
		const Point &	aF,
		const Point &	aL,
		const Point &	aUf,
		const Point &	aUl,
		const Point &	aLf,
		const Point &	aLl
	)

Constructor. Minimal set of parameters to build the DSS in constant time. The user should be sure that the slope is consistent with the position of the leaning points.

Parameters

aA	y-component of the direction vector
aB	x-component of the direction vector
aF	the first point
aL	the last point
aUf	the first upper point
aUl	the last upper point
aLf	the first lower point
aLl	the last lower point

◆ StandardDSS4() [2/6]

template<typename TCoordinate, typename TInteger = TCoordinate>

DGtal::StandardDSS4< TCoordinate, TInteger >::StandardDSS4	(	const Point &	aF,
		const Point &	aL,
		const bool &	isOnTheUpperLine = `true`
	)

Construction of a sequence of patterns (or reversed patterns) from two end points.

Parameters

aF	the first point
aL	the last point
isOnTheUpperLine	boolean equal to 'true' if the two given end points are upper leaning points (pattern case, default), 'false' if they are lower leaning points (reversed pattern case).

NB: logarithmic-time in the greatest component of the vector starting from aF and pointing to aL

◆ StandardDSS4() [3/6]

template<typename TCoordinate, typename TInteger = TCoordinate>

DGtal::StandardDSS4< TCoordinate, TInteger >::StandardDSS4	(	const DSL &	aDSL,
		const Point &	aF,
		const Point &	aL
	)

Construction as the subsegment of minimal parameters of a given DSL.

Parameters

aDSL	bounding DSL
aF	first point of the subsegment
aL	last point of the subsegment

NB: logarithmic-time in the greatest component of the direction vector of the subsegment. Uses smartCH algorithm.

◆ StandardDSS4() [4/6]

template<typename TCoordinate, typename TInteger = TCoordinate>

DGtal::StandardDSS4< TCoordinate, TInteger >::StandardDSS4	(	const StandardDSS4< TCoordinate, TInteger > &	aDSS,
		const Point &	aF,
		const Point &	aL
	)

Construction as the subsegment of minimal parameters of a greater DSS.

Parameters

aDSS	bounding DSS
aF	first point of the subsegment
aL	last point of the subsegment

NB: logarithmic-time in the greatest component of the direction vector of the subsegment. Uses reversedSmartCH algorithm.

	)
throw	(	InputException
	)

Construction from a range of iterators on points.

Parameters

aItb	begin iterator

Copy constructor.

Parameters

aOther the object to clone.
