class SpacingContour2DConstraint : public Constraint

a class corresponding to a position constraint where the distance between 2 vertices is constrained to belong to an interval [minimumDistance,maximumDistance]

Inheritance:

Public Classes

enum	Length edge length expression kind constructor MissingContour (const std::string& from) constructor from a string DIRECT absolute edge length RATIO mean edge length fraction

Public Methods

virtual void	apply (void) the apply fonction that adds or removes vertices depending on minimumDistance and maximumDistance
double	getMinimumSpacing (void) const returns the minimum spacing between two vertices
double	getMaximumSpacing (void) const returns the maximum spacing between two vertices
Length	getLengthKind (void) const returns the edge length kind
void	setMinimumSpacing (const double min) sets the minimum spacing between two vertices
void	setMaximumSpacing (const double max) sets the maximum spacing between two vertices
void	setLengthKind (Length l) sets the edge length kind

Public

	constructor SpacingContour2DConstraint (unsigned int freq, Length length, double min, double max, ActiveContour2D *c) throw(MissingContour) create a spacing constraint
	destructor virtual ~SpacingContour2DConstraint (void) empty destructor

Private Fields

double	minimumSpacing the minimum Spacing between two vertices : may be set to zero
double	maximumSpacing the maximum Spacing between two vertices
Length	length edge length kind
ActiveContour2D*	contour the ActiveContour2D where the constraint is applied

constructor

MissingContour(const std::string& from)

constructor from a string

Parameters:

from - a string indicating where the exception where thrown

DIRECT

absolute edge length

RATIO

mean edge length fraction
