# geojson2image

[![Gem Version](http://img.shields.io/gem/v/geojson2image.svg)][gem]

[gem]: https://rubygems.org/gems/geojson2image

Ruby library for generating images from GeoJSON.

Currently, MultiPolygon and Polygon GeoJSON types should output images properly. Other GeoJSON types have not been thoroughly tested, and properties from the GeoJSON are not being parsed. 

## Installation

You will need [ImageMagick](http://imagemagick.org/) installed. Then Add this line to your application's Gemfile:

```ruby
gem 'geojson2image'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install geojson2image

## Usage

Initialize new Geojson2image::Convert object and call to_image
```ruby
gjson = '{"type":"Feature","geometry":{"type":"MultiPolygon","coordinates":[......'
g2i = Geojson2image::Convert.new(
  json: gjson,
  width: 500,
  height: 500,
  padding: 50,
  background_color: 'white',
  fill_color: 'rgba(0, 158, 40, 0.3)',
  stroke_color: 'rgb(0, 107, 27)',
  stroke_width: 3,
  output: "output.jpg"
)
g2i.to_image
```

### Example Output
