# combine-tiles

**Combine map tiles into a single large image.** Uses the great [`sharp` package](https://www.npmjs.com/package/sharp) for efficiency. Similar to [abacus](https://github.com/mapbox/abaculus#abaculus) and [merge-tiles](https://github.com/stadt-bielefeld/merge-tiles#merge-tiles).

## Installing

```shell

npm install combine-tiles

```

## Usage

Check out the [`example` directory](example)!

```js

const combineTiles = require('combine-tiles')

const size = 300

const tiles = [

	{x: 0, y: 0, file: '/path/to/0-0.png'},

	{x: 1, y: 0, file: '/path/to/1-0.png'},

	{x: 0, y: 1, file: '/path/to/0-1.png'},

	{x: 1, y: 1, file: '/path/to/1-1.png'}

]

const dest = '/path/to/combined.png'

await combineTiles(tiles, size, size, dest)

```

You may want to use [tilebelt](https://github.com/mapbox/tilebelt#features) to convert bounding boxes into `[x, y, zoom]` tiles or [tile-cover](https://github.com/mapbox/tile-cover#tile-cover) to generate a list of tiles in a bounding box.
