svg_path_ops

Crates.io Documentation License

This crate includes utility functions to work with svg paths. Works on types from svgtypes crate.

This package exposes functions to manipulate svg paths with simplification purposes.

📦 Cargo.toml

🔧 Example

use svgtypes::{PathParser, PathSegment};

let path: String = "m 0 0 c 3 -0.6667 6 -1.3333 9 -2 a 1 1 0 0 0 -8 -1 a 1 1 0 0 0 -2 0 l 0 4 v 2 h 8 q 4 -10 9 -5 t -6 8 z".into();
let path_parser = PathParser::from(path.as_ref());
let path_segments: Vec<PathSegment> = path_parser.flatten().collect();
let mut absolute = absolutize(path_segments.iter());
assert_eq!(
    absolute.next().unwrap(),
    PathSegment::MoveTo { abs: true, x: 0.0, y: 0.0 }
);
assert_eq!(
    absolute.next().unwrap(),

        x: 9.0,
        y: -2.0
    }

    absolute.next().unwrap(),
    PathSegment::EllipticalArc {
