%Docstring
|
|
Construct a circular string from arrays of coordinates. If the z or m
|
|
arrays are non-empty then the resultant circular string will have z and
|
|
m types accordingly.
|
|
|
|
This constructor is more efficient then calling
|
|
:py:func:`~QgsCircularString.setPoints`.
|
|
|
|
If the sizes of ``x`` and ``y`` are non-equal then the resultant
|
|
circular string will be created using the minimum size of these arrays.
|
|
|
|
.. warning::
|
|
|
|
It is the caller's responsibility to ensure that the supplied arrays
|
|
are of odd sizes.

|
Creates a circular string with a single arc representing the curve from

``p1`` to ``p2`` with the specified ``center``.
|
|
|
|
If ``useShortestArc`` is ``True``, then the arc returned will be that

|
corresponding to the shorter arc from ``p1`` to ``p2``. If it is
|
|
``False``, the longer arc from ``p1`` to ``p2`` will be used (i.e.
|
|
winding the other way around the circle).
