DGtal::functors::FlipDomainAxis< TDomain > Class Template Reference

Aim: Functor that flips the domain coordinate system from some selected axis. For instance, if a flip on the y axis is applied on a domain of bounds (0, 0, 0) (MaxX, MaxY, MaxZ), then the coordinate of P(x,y,z) will transformed in P(x, MaxY-y, z). More...

Detailed Description

template<typename TDomain>
class DGtal::functors::FlipDomainAxis< TDomain >

Aim: Functor that flips the domain coordinate system from some selected axis. For instance, if a flip on the y axis is applied on a domain of bounds (0, 0, 0) (MaxX, MaxY, MaxZ), then the coordinate of P(x,y,z) will transformed in P(x, MaxY-y, z).

Description of template class 'FlipDomainAxis'

Such functor can be useful to apply basic image flip from some specific axis directions.

◆ FlipDomainAxis()

template<typename TDomain>
DGtal::functors::FlipDomainAxis< TDomain >::FlipDomainAxis ( const TDomain & aSourceDomain,
const std::vector< Dimension > & axisFlipped )
inline

Constructor. Construct the functor from a source domain and a vector defining the axis being flipped. Such a vector should contain the dimension number associated to the axis to be flipped. For instance to flip the x and z axis of a given 3d domain you have to give a vector containing 1 and 2.

Parameters
aSourceDomainthe source domain.
axisFlippeda vector containing the indices of the dimension to be flipped.

Member Function Documentation

◆ operator()()

template<typename TDomain>
Point DGtal::functors::FlipDomainAxis< TDomain >::operator() ( const Point & aPoint) const
inline

The operator computes the coordinates of the point in the flipped domain.

Parameters
aPointa source point.
Returns
the point with flipped coordinates according the source domain.
