Crate geo_clipper[−][src]

Expand description

This crate allows to perform boolean and offset operations on polygons.

It makes use of clipper-sys which is a binding to the C++ version of Clipper.

Example

The following example shows how to compute the intersection of two polygons.
The `intersection` method (as well as `difference`, `union` and `xor`) is provided by the `Clipper` trait which is implemented for some geo-types.

``````use geo_types::{Coordinate, LineString, Polygon};
use geo_clipper::Clipper;

let subject = Polygon::new(
LineString(vec![
Coordinate { x: 180.0, y: 200.0 },
Coordinate { x: 260.0, y: 200.0 },
Coordinate { x: 260.0, y: 150.0 },
Coordinate { x: 180.0, y: 150.0 },
]),
vec![LineString(vec![
Coordinate { x: 215.0, y: 160.0 },
Coordinate { x: 230.0, y: 190.0 },
Coordinate { x: 200.0, y: 190.0 },
])],
);

let clip = Polygon::new(
LineString(vec![
Coordinate { x: 190.0, y: 210.0 },
Coordinate { x: 240.0, y: 210.0 },
Coordinate { x: 240.0, y: 130.0 },
Coordinate { x: 190.0, y: 130.0 },
]),
vec![],
);

let result = subject.intersection(&clip, 1.0);``````
