§Polylabels

§Description

Find the labels for a collection of vector polygons

§Usage

use gistools::tools::{PolyLabelMetadata, polylabels};
use s2json::VectorPoint;

let data: Vec<Vec<Vec<VectorPoint<()>>>> = vec![vec![vec![]]];
let emp: Vec<VectorPoint<PolyLabelMetadata>> = polylabels(&data, None);

assert_eq!(emp, vec![VectorPoint::new_xy(0., 0., Some(PolyLabelMetadata::new(0.)))]);

§Parameters

  • polygons: the vector multi-polygon to find the label for
  • precision: the precision of the label

§Returns

The collection of label positions and the distances to the labels
