- New things:
- CAPI: GEOSBufferWithParams (allows single sided buffers)
- CAPI: GEOSOffsetCurve deprecates GEOSSingleSidedBuffer
- CAPI: GEOSUnaryUnion deprecates GEOSCascadedUnion
- CAPI: GEOSisValidDetail: tell state, reason & location apart. allows
passing flags.
- CAPI: GEOSContext_setNoticeHandler_r, GEOSContext_setErrorHandler_r
- CAPI: GEOSGeom_createEmptyPoint, GEOSGeom_createEmptyLineString
GEOSGeom_createEmptyPolygon, GEOSGeom_createEmptyCollection
- CAPI: GEOSGeom_extractUniquePoints
- CAPI: GEOSGetGeometryN support for single geometries
- CAPI: GEOSPolygonize_full to return all informations computed by
the polygonizer
- CAPI: GEOSOrientationIndex
- CAPI: GEOSSharedPaths to find shared paths and their orientation
- CAPI: GEOSSnap
- CAPI: GEOSRelatePatternMatch
- CAPI: GEOSCovers, GEOSCoveredBy
- CAPI: GEOSRelateBoundaryNodeRule
- PHP: new PHP5 bindings based on CAPI
- Semantic C++ API changes:
- Geometry inheritance chain changed to introduce Puntal, Lineal
and Polygonal classes (virtual inheritance introduced)
- Polygonizer::getInvalidRingLines retains ownership of vector elements
- Geometry::isWithinDistance method is now const
- Polygonizer::getCutEdges returns by const ref
- Polygonizer::getDangles returns by const ref
- Empty LinearRings are closed by definition
- Bug fixes / improvements
- Fixed Geometry.distance() and DistanceOp to return 0.0 for empty inputs
- Invalid compound geometries reported as valid
- Return up to 15 digits of precision from GEOSisValidReason_t
- CAPI: do not leak contexts when using the non-reentrant interface
- Fix duplicated dangles returned by Polygonizer
- Fix SnapIfNeededOverlayOp to throw the originating exception
- Fixed LineMerger to skip lines with only a single unique coordinate
- Fix NodedSegmentString to handle zero-length line segments correctly
(via safeOctant)
- Fixed buffer OffsetCurveSetBuilder to handle "flat" rings correctly
- Added illegal state check in LineSegment::pointAlongOffset()
- Improved performance of RectangleIntersects by always using
segment-scanning and refining SegmentIntersectionTester
- Reduce memory use in PreparedGeometry predicates
- Fix infinite loop in RobustDeterminant with nan/inf input
