Detailed Description

Computes the Euclidean distance (L2 metric) from a Point to a Geometry.

Also computes two points which are separated by the distance.

Member Function Documentation

◆ getCenter() [1/2]

std::unique_ptr<geom::Point> geos::algorithm::construct::MaximumInscribedCircle::getCenter ( )

Gets the center point of the maximum inscribed circle (up to the tolerance distance).

Returns
the center point of the maximum inscribed circle

◆ getCenter() [2/2]

static std::unique_ptr<geom::Point> geos::algorithm::construct::MaximumInscribedCircle::getCenter ( const geom::Geometry polygonal,
double  tolerance 
)
static

Computes the center point of the Maximum Inscribed Circle of a polygonal geometry, up to a given tolerance distance.

Parameters
polygonala polygonal geometry
tolerancethe distance tolerance for computing the center point
Returns
the center point of the maximum inscribed circle

◆ getRadiusLine() [1/2]

std::unique_ptr<geom::LineString> geos::algorithm::construct::MaximumInscribedCircle::getRadiusLine ( )

Gets a line representing a radius of the Largest Empty Circle.

Returns
a line from the center of the circle to a point on the edge

◆ getRadiusLine() [2/2]

static std::unique_ptr<geom::LineString> geos::algorithm::construct::MaximumInscribedCircle::getRadiusLine ( const geom::Geometry polygonal,
double  tolerance 
)
static

Computes a radius line of the Maximum Inscribed Circle of a polygonal geometry, up to a given tolerance distance.

Parameters
polygonala polygonal geometry
tolerancethe distance tolerance for computing the center point
Returns
a line from the center to a point on the circle

◆ getRadiusPoint()

std::unique_ptr<geom::Point> geos::algorithm::construct::MaximumInscribedCircle::getRadiusPoint ( )

Gets a point defining the radius of the Maximum Inscribed Circle. This is a point on the boundary which is nearest to the computed center of the Maximum Inscribed Circle. The line segment from the center to this point is a radius of the constructed circle, and this point lies on the boundary of the circle.

Returns
a point defining the radius of the Maximum Inscribed Circle
