# simplify

  simplify is a high-performance JavaScript polyline simplification library

  If you only need a 2D simplification library, check out [microjs/simplify-2D](https://github.com/microjs/simplify-2D).

  If you only need a 3D simplification library, check out [microjs/simplify-3D](https://github.com/microjs/simplify-3D).

## Installation

    $ component install microjs/simplify

## API

  ```javascript

  var simplify = require('simplify');

  simplify['2D'](points, tolerance, highQuality);

  simplify['3D'](points, tolerance, highQuality);

  ```

  Returns a simplified array of points

  - `points` - An array of points in the format: `{x: Number, y: Number}` or `{x: Number, y: Number, z: Number}`

  - `tolerance` - Optional number (defaulting to 1) Affects the amount of simplification (in the same metric as the point coordinates).

  - `highQuality` - Optional boolean (defaults to false) - Excludes distance-based preprocessing step which leads to higher quality but runs ~10-20 times slower.
