A port of the equivalent method from GEOS, but with added support for curved geometries and M values Reorganizes the geometry into a normalized form (or "canonical" form). Polygon rings will be rearranged so that their starting vertex is the lower left and ring orientation follows the right hand rule, collections are ordered by geometry type, and other normalization techniques are applied. The resultant geometry will be geometrically equivalent to the original geometry.

in the vector.

|
%Docstring
|
|
Construct a linestring from arrays of coordinates. If the z or m
|
|
arrays are non-empty then the resultant linestring will have
|
|
z and m types accordingly.
|
|
This constructor is more efficient then calling :py:func:`~QgsLineString.setPoints`
|
|
or repeatedly calling :py:func:`~QgsLineString.addVertex`
|
|
|
|
If the ``z`` vector is filled, then the geometry type will either
|
|
be a LineStringZ(M) or LineString25D depending on the ``is25DType``
|
|
argument. If ``is25DType`` is ``True`` (and the ``m`` vector is unfilled) then
|
|
the created Linestring will be a LineString25D type. Otherwise, the
|
|
LineString will be LineStringZ (or LineStringZM) type.
|
|
|
|
If the sizes of ``x`` and ``y`` are non-equal then the resultant linestring
|
|
will be created using the minimum size of these arrays.
