Detailed Description

template<typename CalculationType = void, typename Strategy = pythagoras<CalculationType>>
class boost::geometry::strategy::distance::projected_point< CalculationType, Strategy >

Strategy for distance point to segment.

Calculates distance using projected-point method, and (optionally) Pythagoras

Template Parameters

CalculationType
Strategy	underlying point-point distance strategy

Concepts for Strategy:

• cartesian_distance operator(Point,Point)

Note

If the Strategy is a "comparable::pythagoras", this strategy automatically is a comparable projected_point strategy (so without sqrt)
