Now all classes and members are either exposed to bindings or marked
as "not available in Python bindings" in the docs.
Drop test thresholds to 0. Now it should be much easier to determine
what missing members have been added which are causing test
failures.
- 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
- 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
- when creating geometry from WKT, upgrade dimensionality of geometry
if coordinates are 3/4 dimensional
- match dimensionality of collections to child dimensionality
- fix area of curves was non-zero if curve is closed
- don't consider m values when testing for curve closedness
- add unit tests for closedness
- add unit tests for CircularStrings, CompoundCurves, CurvePolygon,
tests with geometries with Z/M values
Split length from perimeter calculation in geometry API, as
returning perimeter for length for polygons is misleading and
results in incorrect length/perimeter calculations for mixed
geometry collections.
Enable length & perimeter unit tests against reference geometries.
Now the length & perimeter values match those calculated by
PostGIS.
- Add some tests for conversion to/from WKT, using a bulk lot of testsdata
from PostGIS
- Add some tests for area/length calculation, using some test data and
results from PostGIS/geos unit tests
- Add tests for spatial relations, using test data from PostGIS. Note
that this required adding support for calculating the DE-9IM relation. I'll
expose this to users via the expression engine in 2.14.
Along the way this also fixes a number of bugs relating to WKT geometry
import, such as
- add support for alternate MultiPoint(1 1,2 2,...) format
- fix GeometryCollection to support collections with multi* children
and GeometryCollection children (allowed by spec)
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!
- call reserve on container classes where applicable
- make sure Q_FOREACH uses references
- remove dynamic casts to base classes
- fix some implicit bool conversions
