Returns a reference to the simplest lossless representation of this geometry, e.g. if the geometry is a multipart geometry type with a single member geometry, a reference to that part will be returned. This method employs the following logic: - For multipart geometries containing a single part only a direct reference to that part will be returned. - For compound curve geometries containing a single curve only a direct reference to that curve will be returned. This method returns a reference only, and does not involve any geometry cloning.

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.
