Package org.locationtech.jts.algorithm
Class MinimumAreaRectangle
java.lang.Object
org.locationtech.jts.algorithm.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 MinimumDiameter
to compute this.
