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.

Adds a curve to the geometry (takes ownership).
|
|
|
|
Since QGIS 3.20, if ``extendPrevious`` is ``True``, then adding a LineString when the last existing curve
|
|
in the compound curve is also a LineString will cause the existing linestring to be
|
|
extended with the newly added LineString vertices instead of appending a whole new
|
|
LineString curve to the compound curve. This can result in simplified compound curves with lesser number
|
|
of component curves while still being topologically identical to the desired result.
