Just passing this along to GeoMason users since GeoMason relies heavily on JTS. You might want this version given its bug fixes. In any case, I'll be updating the GeoMason site in a bit to reflect the advent of JTS 1.13. ---------- Forwarded message ---------- From: Martin Davis <[log in to unmask]> Date: Thu, Dec 13, 2012 at 12:10 PM Subject: [Jts-topo-suite-user] JTS 1.13 released To: "[log in to unmask]" < [log in to unmask]> I'm happy to announce that JTS 1.13 has been released and is now available for download from SourceForge at http://sourceforge.net/projects/jts-topo-suite/ There are many new features, improvements and bug fixes in this release.

Robustness Improvements - Switched to using DD extended-precision arithmetic to compute orientation predicate - CGAlgorithms.distanceLineLine() improved to be more robust and performant - Fixed robustness issue causing Empty Stack failure in ConvexHull for some nearly collinear inputs - CGAlgorithms.signedArea() uses a more accurate algorithm Bug Fixes - Fixed Geometry.equalsExact() to avoid NPE when comparing empty and non-empty Points - Fixed CascadedPolygonUnion to discard non-polygonal components created during unioning, to avoid failures and provide more desirable behaviour - Fixed CentralEndpointIntersector to initialize result correctly - Fixed DelaunayTriangulationBuilder.extractUniqueCoordinates(Geometry)to avoid mutating the vertex order of the input Geometry - Fixed ConformingDelaunayTriangulationBuilder to allow non-disjoint site and constraint vertex sets - Fixed RandomPointsInGridBuilder point generation to use circle constraint correctly - Fixed Linear Referencing API to handle MultiLineStrings consistently, by always using the lowest possible index value, and by trimming zero-length components from results - Fixed bug in LocationIndexedLine and LengthIndexLine which was causing an assertion failure when the indexOfAfter() method was called with a constraint location which is at the end of the line - Fixed bug in STRtree.query(Envelope, ItemVisitor) causing an NPE when tree is empty - Fixed issue with creating zero-length edges during buffer topology building under fixed precision, by: adding filter to remove zero-length edges; using a better estimate of scale factor for reducing to fixed precision after initial failure. - Fixed TopologyPreservingSimplifier to return a valid result for closed LineStrings with large distance tolerances - Fixed TopologyPreservingSimplifier to return an empty result for an empty input - Fixed DouglasPeuckerSimplifier to return an empty result for an empty input - Fixed MinimumBoundingCircle to correctly compute circle for obtuse triangles. - Fixd GeometryPrecisionReducer to use input GeometryFactory when polygon topology is fixed - Fixed GeometryNoder bug that was failing to snap to end vertices of lines - Fixed Geometry.getCentroid() and Geometry.getInteriorPoint() to return POINT EMPTY for empty inputs - Fixed DelaunayTriangulationBuilder to correctly extract unique points - Fixed KdTree to correctly handle inserting duplicate points into an empty tree - Fixed LineSegment.projectionFactor() to handle zero-length lines (by returning Double.POSITIVE_INFINITY) - Fixed LocationIndexedLine to handle locations on zero-length lines - Fixed LengthIndexedLine and LocationIndexedLine to handle indexOfAfter() correctly - Fixed WKBReader to handle successive geometrys with different endianness - Fixed GeometricShapeFactory to correctly handle setting the centre point - Fixed GeometryFactory.createMultiPoint(CoordinateSequence) to handle sequences of dimension > 3 API Changes - Changed visibility of TaggedLineStringSimplifier back to public due to user demand Testing - Added Performance Testing framework (PerformanceTestRunner and PerformanceTestCase) - Added named predicate tests to all Relate test cases Contributors - Peter Hopfgartner - improved area computation - Michael Michaud - snap-rounding improvements ------------------------------ JTS TestBuilder Functionality Improvements - Added segment index visualization styling - Improved *Geometry Inspector* - Added stream digitizing for Polygon and LineString tools - Added output of Test Case XML with WKB - Added Extract Component tool - Added Delete Vertices Or Components tool - Added Geometry Edit Panel pop-up menu, with operations - Added Halton sequence functions - Added sorting functions - Added function for selection of first N components - Added CGAlgorithms functions - Added ability to paste and load multiple WKBHex geometries Performance Improvements - Using decimation substantially improves rendering time for large geometries.
