lwgeom_transform_pipeline()

int lwgeom_transform_pipeline	(	LWGEOM *	geom,
		const char *	pipeline,
		bool	is_forward
	)

Transform (reproject) a geometry in-place using a PROJ pipeline.

Parameters

geom	the geometry to transform
pipeline	the coordinate operation pipeline string. Either: urn:ogc:def:coordinateOperation:AUTHORITY::CODE a PROJ pipeline string: +proj=pipeline ... concatenated operations: urn:ogc:def:coordinateOperation,coordinateOperation:EPSG::3895,coordinateOperation:EPSG::1618
is_forward	whether to execute the pipeline in a forward or inverse direction.
