  • Method Details

    • buffer

      Geometry buffer(Geometry geometry, double distance, SpatialReference sr, double densify_dist, int max_vertex_in_complete_circle, ProgressTracker progress_tracker)
      Result is always a polygon. For non positive distance and non-areas returns an empty polygon. For points returns circles.
