[Gvsig_desarrolladores] [Fwd: [Jts-topo-suite-user] JTS Version 1.11 released]

[Francisco José Peñarrubia]

Hola.

Acaba de salir la versión 1.11 de la librería JTS.

Creo que nos vendría bien usar esta versión en gvSIG (2.0).

Saludos.

Fran.

JTS Version 1.11 is now available for download from SourceForge.

http://sourceforge.net/projects/jts-topo-suite/

Highlights of this version include:

* Delaunay triangulation and Voronoi diagrams
* AWT Shape reading and writing
* Geometry similarity metrics
* support for Geometry densification
* Numerous improvements to the JTS TestBuilder

Full Version Details

Functionality Improvements

    * Added CoordinateArrays.isRing
    * Added CGAlgorithms.signedArea(CoordinateSequence)
    * Added CoordinateArrays.copyDeep(...) method to copy sections of arrays
    * Added CoordinateList.add(Coordinate[], boolean, int, int) method 
to add sections of arrays
    * Added LineSegment.toGeometry(), LineSegment.lineIntersection()()
    * Added LineSegment.hashCode()
    * Added geometric similarity classes (HausdorffSimilarityMeasure, 
AreaSimilarityMeasure)
    * Added MinimumDiameter.getMinimumRectangle()
    * Added MinimumBoundingCircle class
    * Added Densifier class
    * Added triangulation API, including QuadEdgeSubdivision, 
IncrementalDelaunayTriangulator, ConformingDelaunayTriangulator and 
supporting classes
    * Added VoronoiDiagramBuilder to perform Voronoi diagram generation
    * Added scaleInstance(scaleX, scaleY, x, y) to AffineTransformation
    * Added AffineTransformationFactory to allow generating 
transformations from various kinds of control inputs
    * Added BinTree.remove() method
    * Fixed BinTree.query() to allow null interval arguments
    * Added ShapeReader API to convert Java2D Shapes into JTS Geometry
    * Added ShapeWriter API to convert JTS geometry into Java2D Shapes
    * Added FontGlyphReader API to render Java2D text font glyphs into 
geometry
    * Added SdeReader to jtsio library
    * Added Debug break methods
    * Added Memory utility for reporting memory statistics
    * Added ObjectCounter utility for counting objects
    * Added createSquircle and createSuperCircle to GeometricShapeFactory

Performance Improvements

    * Improved performance of Geometry.getArea() and 
Geometry.getLength() when used with custom CoordinateSequences

API Changes

    * Deprecated WKBWriter.bytesToHex in favour of WKBWriter.toHex to 
regularize and simplify method name

Bug Fixes

    * Fixed Point.isValid() to check for invalid coordinates (ie with 
Nan ordinates)
    * Fixed Geometry.distance() and DistanceOp to return 0.0 for empty 
inputs
    * Fixed Buffer to handle degenerate polygons with too few distinct 
points correctly
    * Added illegal state check in LineSegment.pointAlongOffset()
    * Fixed exception strategy in BufferSubgraph to handle certain 
robustness failures correctly
    * Fixed robustness problem in OffsetCurveBuilder in computing mitred 
joins for nearly parallel segments
    * Fixed minor bug in BufferInputLineSimplifier which prevented 
simplification of some situations
    * Fixed bug in BufferInputLineSimplifier which caused 
over-simplification for large tolerances
    * Fixed bug in Angle.normalizePositive to handle values > 2PI correctly
    * Fixed WKTWriter to emit correct syntax for MULTIPOINTs
    * Fixed WKTReader to accept correct syntax for MULTIPOINTs
    * CGAlgorithms.isCCW now checks for too few points in the ring and 
throws an IllegalArgumentException
    * Fixed bug in AffineTransformation#eqals (logic bug)
    * Fixed bug in CoordinateList#closeRing (cloning closing Coordinate)

JTS TestBuilder

Functionality Improvements

    * WKT input is cleaned automatically when loaded (illegal chars are 
removed)
    * Added WKT-Formatted option to Test Case View dialog
    * Many new geometry functions added
    * Geometry functions are displayed in tree
    * Geometry functions can be implemented as Java static class methods.
    * Geometry function classes can be loaded dynamically from command-line
    * Improved handling of very large geometry inputs and results
    * Threaded rendering allows display of very large geometries without 
limiting usability
    * Added Draw Rectangle tool
    * Added Drag-n-drop loading of .SHP files
    * Added Info tool to provide persistent display of geometry 
point/segment information
    * Added display of memory usage
