class RectangleContour2DConstraint : public Constraint

a class corresponding to a position constraint where all contour edges located outside the rectangle are removed

Inheritance:

Public Methods

virtual void	apply () the apply fonction that cuts all parts of the contour outside the rectangle
void	setFirstCorner (const Vec2 &position) sets the first corner of the rectangle
void	setSecondCorner (const Vec2 &position) sets the second corner of the rectangle
Vec2	getFirstCorner () const get the second corner of the rectangle
Vec2	getSecondCorner () const get the second corner of the rectangle
bool	insideRectangle (Vec2 &pos) returns a boolean corresponding to the test if a point is inside a rectangle

Public

	Constructors RectangleContour2DConstraint (ActiveContour2D *_contour=0, const unsigned int _frequency=1, const Vec2 _first_corner=Vec2(0.0, 0.), const Vec2 _second_corner=Vec2(1., 1.)) throw(MissingContour) constructor of the RectangleContour2DConstraint
	destructor virtual ~RectangleContour2DConstraint (void) empty destructor

Private Fields

Vec2	corner [2] the 2 corners of the rectangle constructor MissingContour (const std::string& from) constructor from a string
ActiveContour2D*	contour the ActiveContour2D where the constraint is applied

Vec2 corner[2]

the 2 corners of the rectangle

constructor

MissingContour(const std::string& from)

constructor from a string

Parameters:

from - a string indicating where the exception where thrown

ActiveContour2D* contour

the ActiveContour2D where the constraint is applied

virtual void apply()

the apply fonction that cuts all parts of the contour outside the rectangle

void setFirstCorner(const Vec2 &position)

sets the first corner of the rectangle

void setSecondCorner(const Vec2 &position)

sets the second corner of the rectangle

Vec2 getFirstCorner() const

get the second corner of the rectangle

Vec2 getSecondCorner() const

get the second corner of the rectangle

bool insideRectangle(Vec2 &pos)

returns a boolean corresponding to the test if a point is inside a rectangle

Constructors

RectangleContour2DConstraint(ActiveContour2D *_contour=0, const unsigned int _frequency=1, const Vec2 _first_corner=Vec2(0.0, 0.), const Vec2 _second_corner=Vec2(1., 1.)) throw(MissingContour)

constructor of the RectangleContour2DConstraint

Throws:

MissingContour when the active contour pointer is 0

Parameters:

_contour - the active contour on which the constraint apply
_frequency - the frequency at which the constraint is called
_first_corner - the first corner of the rectangle
_second_corner - the second corner of the rectangle

destructor

virtual ~RectangleContour2DConstraint(void)

empty destructor
