Function geo_svg_io::geo_svg_reader::svg_d_path_to_geometry_collection

pub fn svg_d_path_to_geometry_collection(
    svg: &str
) -> Result<GeometryCollection<f64>, SvgError>

Parses the d-string from an SVG <path> element into a GeometryCollection

Note that the current parsing of curves is rather simple right now, it just finds 100 points along the curve.

Examples

use geo_svg_io::geo_svg_reader::svg_d_path_to_geometry_collection;
use geo_types::polygon;

let poly = polygon!(
        exterior: [
            (x: 0.0, y: 0.0),
            (x: 0.0, y: 60.0),
            (x: 60.0, y: 60.0),
            (x: 60.0, y: 0.0),
            (x: 0.0, y: 0.0),],
        interiors:[[
            (x: 10.0, y: 10.0),
            (x: 40.0, y: 1.0),
            (x: 40.0, y: 40.0),
            (x: 10.50, y: 40.0),
            (x: 10.0, y: 10.0),]
            ]
        );

let svg_string = String::from("M0 0l0 60l60 0L60 0L0 0M10 10L40 1L40 40L10.5 40L10 10");
let parsed_svg = svg_d_path_to_geometry_collection(&svg_string);
assert_eq!(parsed_svg.is_ok(), true);

// Unwrap the GeometryCollection result
let geom = parsed_svg.ok().unwrap();
assert_eq!(1, geom.0.len());

// Read the geometry as a Polygon
let pl = geom.0[0].clone().into_polygon();
assert_eq!(true, pl.is_some());
assert_eq!(pl.unwrap(), poly);
