Trait Simplify

pub trait Simplify<T, Epsilon = T> {
    // Required method
    fn simplify(&self, epsilon: &T) -> Self
       where T: GeoFloat;
}

Simplifies a geometry.

The Ramer–Douglas–Peucker algorithm simplifies a linestring. Polygons are simplified by running the RDP algorithm on all their constituent rings. This may result in invalid Polygons, and has no guarantee of preserving topology.

Multi* objects are simplified by simplifying all their constituent geometries individually.

An epsilon less than or equal to zero will return an unaltered version of the geometry.

Required Methods

fn simplify(&self, epsilon: &T) -> Self

where T: GeoFloat,

Returns the simplified representation of a geometry, using the Ramer–Douglas–Peucker algorithm

Examples

use geo::Simplify;
use geo::line_string;

let line_string = line_string![
    (x: 0.0, y: 0.0),
    (x: 5.0, y: 4.0),
    (x: 11.0, y: 5.5),
    (x: 17.3, y: 3.2),
    (x: 27.8, y: 0.1),
];

let simplified = line_string.simplify(&1.0);

let expected = line_string![
    (x: 0.0, y: 0.0),
    (x: 5.0, y: 4.0),
    (x: 11.0, y: 5.5),
    (x: 27.8, y: 0.1),
];

assert_eq!(expected, simplified)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
