Subclassed by xlifepp::Homothety

Public Functions

inline Scaling()#: default constructor

inline Scaling(const Parameter &p1)#: main constructor from one key

inline Scaling(const Parameter &p1, const Parameter &p2)#: main constructor from 2 keys

inline Scaling(const Point &c, const std::vector<real_t> &factor = std::vector<real_t>(1, 1.))#: default constructor from a center and a factor

inline Scaling(const std::vector<Parameter> &ps)#: main constructor from a vector of keys

inline virtual ~Scaling()#: destructor

virtual Point apply(const Point &p) const#: computes the image of a point by the transformation

inline const Point &center() const#: returns the center of the homothety

inline virtual Transformation *clone() const#: virtual copy constructor

inline const std::vector<real_t> &factors() const#: returns the scale factors of the scaling

virtual void print(std::ostream&) const#: print Transformation
