# geojson-mapnikify-image
Leverages [geojson-mapnikify](https://github.com/mapbox/geojson-mapnikify) and [node-mapnik](https://github.com/mapnik/node-mapnik)
bindings to take geojson and output a PNG image directly with [mapnik](https://github.com/mapnik/mapnik).
## install
As a dependency:
npm install --save geojson-mapnikify-image
As a binary:
npm install -g geojson-mapnikify-image
## Requirements
geojson-mapnikify assumptions for converting to valid mapnik stylesheet XML:
* GeoJSON is valid, and in EPSG:4326
* Styles, if any, are expressed in simplestyle-spec
* Mapnik **3.x** is the rendering engine
## binary
If you install `-g`, you can use `geojson-mapnikify-image` as a binary that takes
a single GeoJSON file, image size, output filepath, and filename (without extension) as arguments and generates a PNG image.
```bash
geojson-mapnikify-image file.geojson --size 200 --output ./ --filename my_map_name
```
