Hi Team, Just wondering if there is a python api which gets an offset line or parallel line (to both left and right sides) to a given line geometry in Qgis Python. I know there exists a processing tool called Offsetlines <https://docs.qgis.org/3.16/en/docs/user_manual/processing_algs/qgis/vectorgeometry.html#offset-lines> but need this similar functionality at geometry object level so that I can create offset lines only when needed based on my logic.
The only way now is that I can perform the Offset lines on the entire layer and then access the offset geometry if needed. On other hand, shapely has parallel_offset <https://shapely.readthedocs.io/en/stable/manual.html#object.parallel_offset> but this needs conversion from shapely geometry to qgisgeometry. Just looking for thoughts on this to optimize heavy geometry operations. Appreciate your help. -Prem
