Is there any method generating a wedge buffer, as in Creating wedge buffers from many to one in QGIS, using QGIS Python API?

I made a search in QGIS API Documentation and GIS SE.

I'm not looking for a script, only a useful function to generate a wedge buffer for a point.

  • The trigonometry for making a "buffer" that shape from a given point, distances, and angles isn't that hard, so you could code it in Python from scratch.

  • @Spacedman I needed a quick solution now. I will probably need my own wedge buffer function that has different properties. Thank you.

Yes. Import these:

>>> from qgis.core import QgsGeometry, QgsPoint

Then:

>>> QgsGeometry.createWedgeBuffer(QgsPoint(1,2), 25, 5, 2, )
<QgsGeometry: CurvePolygon (CompoundCurve (CircularString (1.76536686473017967 3.84775906502257348, 1.84523652348139877 3.8126155740733001, 1.92349722647006782 3.77402166635644321),(1.92349722647006782 3.77402166635644321, 1 2),(1 2, 1.76536686473017967 3.84775906502257348)))>
