lineclip

A very fast JavaScript library for clipping polylines and polygons by a bounding box.

lineclip(
    [[-10, 10], [10, 10], [10, -10]], // line
    [0, 0, 20, 20]); // bbox
// returns [[[0, 10], [10, 10], [10, 0]]]

Returns an array of clipped lines.

lineclip is an alias to lineclip.polyline.

Returns a clipped polygon.

Install with NPM:

npm install lineclip

To build a browser-compatible version, clone the repository locally, then run:

npm install -g browserify
browserify -s lineclip index.js > lineclip.js
