segments shorter than a certain threshold or sharp corners
with an angle exceeding a threshold
Expose the angle threshold to processing smooth algorithm
Also:
- optimise QgsGeometry::smooth for new geometry classes
- Fix smooth does not work with geometries containing Z/M
* Make closestSegment() behave as expected by QgsGeometry::closestSegmentWithContext
This fixes a bug that QgsPointLocator::nearestEdge() would return valid match even for point layers.
* Shortcut if using QgsPointLocator with a wrong layer type
* Remove deprecated Qgis::WKBType and API cleanup
Renames QgsWKBTypes to QgsWkbTypes
Replaces usage of the enums:
* Qgis::WKBType with QgsWkbTypes::Type
* Qgis::GeometryType with QgsWkbTypes::GeometryType
Their values should be forward compatible (a fact that was already
explited up to now by casting between the types)
Renames some SSLxxx to SslXxx and URIxxx to UriXxx
* Fix build warnings and simplify type handling
* Add a fixer to rewrite imports
* The forgotten rebase conflictThe forgotten rebase conflicts
* QgsDataSourcURI > QgsDataSourceUri
* QgsWKBTypes > QgsWkbTypes
* Qgis.WKBGeom > QgsWkbTypes.Geom
* Further python fixes
* Guess what... Qgis::wkbDimensions != QgsWkbTypes::wkbDimensions
* Fix tests
* Python 3 updates
* [travis] pull request caching cannot be disabled
so at least use it in r/w mode
* Fix python3 print in plugins
Returns the closure of the combinatorial boundary of the
geometry (ie the topological boundary of the geometry).
For instance, a polygon geometry will have a boundary
consisting of the linestrings for each ring in the polygon.
Follows OGC / SQL/MM specs for boundary calculation
implicitly shared copy of an internal cache instead of recreating the
coordinate sequence again and again.
Improves performance of the nodetool on large features a lot (refs #13963)
Also introduce Qgs(Coordinate|Ring|Point)SequenceV2 typedefs.
- Setting exterior ring will force all interior rings to match
dimensionality of exterior ring
- add equality operator
- use correct WKB types for rings when creating polygon from WKB
- segmentize curves when setting exterior ring with curved segments
- fix export to GML2/3 (should use LinearRing, not LineString as
ring element tag)
- fixes for handling Polygon25D
- add QgsAbstractGeometryV2::convertTo( QgsWKBTypes::Type type ) for
easy conversion between geometry types
- fix crash when calculating perimeter with no exterior ring
- ensure that added rings respect dimensionality of polygon (avoids
issues such as polygons with z having a ring without z, or a
Polygon25D with LineStringZ rings)
- if a curved ring is added to a polygon then a segmentized version
of the ring is used (can't have a Polygon with a CircularString
ring)
- when calling setInteriorRings, make sure empty rings are skipped
and that all rings are converted to correct type for polygon
- don't crash when requesting or removing interior ring with
index < 0
- add QgsGeometryUtils::normalizedAngle for restricting an angle
to [0, 2PI)
- fix calculations of QgsGeometryUtils::averageAngle, was returning
perpendicular angle and angles > 2Pi
- improve docs and add unit tests
- fix incorrect centroid calculation (was always returning 0,0)
- fix closestSegment when numPoints < 2
- fix broken leftOf calculation for closestSegment
- area calculation when numPoints < 2
Plus add more unit tests
- prevent creation of a QgsPointV2 with a non-point WKB type
- fix bounding box was not invalidated for some modification routines
- if WKT type is PointZ/M/ZM and not enough coordinates specified,
initialise extra coordinates to 0
QString methods
Using single quotes is a significant performance boost. Rough
benchmarks indicate the QString single quote methods take
about 15% of the time the double quote variants take.
Rationale:
- there was a lot of large objects passed by value, so potentially
there's a speed bump from this
- even for implicitly shared classes like QString/QList there's still
a (small) cost for copying the objects when there's no reason to
- it's the right thing to do!
