Trait geo::algorithm::simplifyvw::SimplifyVW [−] [src]

pub trait SimplifyVW<T, Epsilon = T> {
    fn simplifyvw(&self, epsilon: &T) -> Self where T: Float;
}

Required Methods

Returns the simplified representation of a LineString, using the Visvalingam-Whyatt algorithm

See here for a graphical explanation 

use geo::{Point, LineString};
use geo::algorithm::simplifyvw::{SimplifyVW};

let mut vec = Vec::new();
vec.push(Point::new(5.0, 2.0));
vec.push(Point::new(3.0, 8.0));
vec.push(Point::new(6.0, 20.0));
vec.push(Point::new(7.0, 25.0));
vec.push(Point::new(10.0, 10.0));
let linestring = LineString(vec);
let mut compare = Vec::new();
compare.push(Point::new(5.0, 2.0));
compare.push(Point::new(7.0, 25.0));
compare.push(Point::new(10.0, 10.0));
let ls_compare = LineString(compare);
let simplified = linestring.simplifyvw(&30.0);
assert_eq!(simplified, ls_compare)
