Class MinimumAreaRectangle

Computes the minimum-area rectangle enclosing a Geometry. Unlike the Envelope, the rectangle may not be axis-parallel.

The first step in the algorithm is computing the convex hull of the Geometry. If the input Geometry is known to be convex, a hint can be supplied to avoid this computation.

In degenerate cases the minimum enclosing geometry may be a LineString or a Point.

The minimum - area enclosing rectangle does not necessarily have the minimum possible width. Use {@link MinimumDiameter} to compute this.

Syntax

public sealed class MinimumAreaRectangle

Constructors

MinimumAreaRectangle(Geometry)

Compute a minimum-area rectangle for a given {@link Geometry}.

Declaration

public MinimumAreaRectangle(Geometry inputGeom)

Parameters

Type	Name	Description
Geometry	inputGeom	A Geometry

MinimumAreaRectangle(Geometry, bool)

Compute a minimum rectangle for a Geometry, with a hint if the geometry is convex (e.g. a convex Polygon or LinearRing, or a two-point LineString, or a Point).

Declaration

public MinimumAreaRectangle(Geometry inputGeom, bool isConvex)

Parameters

Type	Name	Description
Geometry	inputGeom	A Geometry
bool	isConvex	A flag indicating if inputGeom is convex

Methods

GetMinimumRectangle(Geometry)

Gets the minimum-area rectangular {@link Polygon} which encloses the input geometry. If the convex hull of the input is degenerate (a line or point) a {@link LineString} or {@link Point} is returned.

Declaration

public static Geometry GetMinimumRectangle(Geometry geom)

Parameters

Type	Name	Description
Geometry	geom	A Geometry

Returns

Type	Description
Geometry	The minimum rectangle enclosing the geometry
