simplify-polyline

A nearly line-by-line Rust port of the Javascript simplify-js library.

Examples

use simplify_polyline::*;

fn main() {
    let points = &[
        Point { x: 0.0, y: 0.0 }, Point { x: 1.0, y: 1.0 },
        Point { x: 2.0, y: 2.0 }, Point { x: 3.0, y: 3.0 },
        Point { x: 4.0, y: 4.0 }
    ];
    // alternatively, use the point! macro
    let points = &[
        point!(f64, 0.0, 0.0), point!(f64, 1.0, 1.0), point!(f64, 2.0, 2.0),
        point!(f64, 3.0, 3.0), point!(f64, 4.0, 4.0)
    ];
    // alternatively, use the points! macro
    let points = points![f64, (0.0, 0.0), (1.0, 1.0), (2.0, 2.0), (3.0, 3.0), (4.0, 4.0)];

    // low-quality simplification (fast)
    let new_points = simplify(points, 1.0, false);
    // low-quality simplification (slower)
    let new_points = simplify(points, 1.0, true);
}
