geo-clipper

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.

```rust use geotypes::{Coordinate, LineString, Polygon}; use geoclipper::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); ```
