Status](https://github.com/21re/rust-geo-booleanop/actions/workflows/ci.yml/badge.svg)](https://github.com/21re/rust-geo-booleanop/actions/workflows/ci.yml)\n[![crates.io](https://img.shields.io/crates/v/geo-booleanop.svg)](https://crates.io/crates/geo-booleanop)\n\n\n# Boolean operations on geo shapes\n\nThis is an implementation of the [Martinez-Rueda Polygon Clipping Algorithm](http://www.cs.ucr.edu/~vbz/cs230papers/martinez_boolean.pdf) in rust to integrate smoothly into the already exsting geospatial library  [georust/geo](https://github.com/georust/geo).\n\nIn fact the implementation closely follows the \"reference\" implementation in JavaScript: [https://github.com/w8r/martinez](https://github.com/w8r/martinez). Most of the concepts and fixtures have been taken from there.\n\nAt the moment the implementation contains its own splay tree implementation (adapted from [https://github.com/alexcrichton/splay-rs](https://github.com/alexcrichton/splay-rs)) as the JavaScript implementation also uses a splay-tree. This might be refactored out in the future in favor of the standard collection types (like BTreeSet).\n\n# IMPORTANT: How to report bugs\n\nPlease be aware (so far) this implementation is based on the JavaScript version. If you find a bug (i.e. two polygons not producing the expected result), chances are that the original algorithm has the same problem. So please first check with [https://github.com/w8r/martinez](https://github.com/w8r/martinez) and file a report there. Once there is a fix I will happily backport it to the rust version.\n\nIf you do not know how to do that (You understand rust but not javascript? ... I mean ... seriously?), you may take a look at this example: https://gist.github.com/untoldwind/e95b7eff8ad61527a5dc4bdd889169b0\n\nI.e. just create `package.json`, ìnsert your example coordinates in `main.js` and then do `npm install` followed by `node main.js`\n\n# Usage\n\nPretty straightforward:\n\n```\ngeo-booleanop = \"0.2.1\"\n```\n\n```rust\nextern create geo;\nextern crate geo_booleanop;\n\nuse geo_booleanop::boolean::BooleanOp;\n\nfn main() {\n    let poly1 : geo::Polygon\u003cf64\u003e = ...\n    let poly2 : geo::Polygon\u003cf64\u003e = ...\n\n    let intersect = poly1.intersection(\u0026poly2);\n    let union = poly1.union(\u0026poly2);\n    let diff = poly1.difference(\u0026poly2);\n    let xor = poly1.xor(\u0026poly2);\n\n    ...\n}\n```\n\nMultiPolygon is supported as well.\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2F21re%2Frust-geo-booleanop","html_url":"https://awesome.ecosyste.ms/projects/github.com%2F21re%2Frust-geo-booleanop","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2F21re%2Frust-geo-booleanop/lists"}
