JTS Topology Suite v1.17.0 Release Notes

Release Date: 2020-06-30 // almost 4 years ago
  • Java Version: 1.8

    API Changes

    • ๐Ÿ”„ Change Polygon getExteriorRing and getInteriorRingN accessors to return LinearRing.

    • โž• Added Envelope methods getDiameter, copy, disjoint (#483)
    • โž• Added Intersection class, refactored library to use it (#468)
    • โž• Added CascadedPolygonUnion union-by-buffer on error capability (#470)
    • โž• Added HalfEdge support for direction points (#479)
    • โž• Added CoordinateList.toCoordinateArray(isForward) (#482)
    • โž• Addded HPRtree Hilbert Packed R-tree (#494)
    • โž• Added VariableBuffer class for computing varying-distance buffers (#495)
    • โž• Added LineSegment.reflect method (#495)
    • โž• Added MaximumInscribedCircle algorithm (#530)
    • โž• Added LargestEmptyCircle algorithm (#530)

    ๐ŸŽ Performance Improvements
