README
## Leaflet-IIIF
A Leaflet plugin for viewing IIIF images. [See the demo](http://mejackreed.github.io/Leaflet-IIIF/examples/example.html)
Requires [Leaflet.js](http://leafletjs.com/).
Leaflet-IIIF relies on browser support for [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) and [Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API). If you need to support IE or other browsers without this, please use a polyfill.
**Note on Leaflet Compatibility**
| Leaflet Versions | Leaflet-IIIF Versions |
| ---------------- | --------------------- |
| < 1.0.0 | < 1.0.0 |
| >= 1.0 | >= 1.0 |
### Examples
- [Demo using the IIIF Image API](http://mejackreed.github.io/Leaflet-IIIF/examples/example.html)
- [Demo parsing a IIIF manifest](http://mejackreed.github.io/Leaflet-IIIF/examples/manifest.html)
### Install with NPM
```
$ npm install leaflet-iiif --save
```
### Quick and easy to get going.
```
import 'leaflet-iiif';
var map = L.map('map', {
center: [0, 0],
crs: L.CRS.Simple,
zoom: 0
});
L.tileLayer.iiif('http://example.com/iiifimage.jp2/info.json').addTo(map);
```
Thanks to [klokantech/iiifviewer](https://github.com/klokantech/iiifviewer) and [turban/Leaflet.Zoomify](https://github.com/turban/Leaflet.Zoomify) who have similar plugins which were used in development of Leaflet-IIIF.
### Options
Leaflet-IIIF extends [L.TileLayer](http://leafletjs.com/reference.html#tilelayer) and so many options available to L.TileLayer can be used with Leaflet-IIIF.
Option | Type | Default | Description
------ | ---- | ------- | -----------
`tileFormat` | `String` | `'jpg'` | The [format](http://iiif.io/api/image/2.0/#format) of the returned image.
`tileSize` | Number | 256 | Tile size (width and height in pixels, assuming tiles are square).
`fitBounds` | Boolean | true | Automatically center and fit the maps bounds to the added IIIF layer
`setMaxBounds` | Boolean | false | Constrain the map viewer to the image
`quality` | String | 'default' | [determines whether the image is delivered in color, grayscale or black and white](http://iiif.io/api/image/2.0/#quality) _Note:_ All IIIF servers do not support this parameter.

### Leaflet-IIIF in the wild
- Europeana uses Leaflet-IIIF for viewing image content. See more about how they do this ["Building a rich media experience with the Europeana API and IIIF"](http://labs.europeana.eu/blog/building-a-rich-media-experience-with-the-europeana-api-and-iiif) and an example at [http://www.europeana.eu/portal/en/record/9200211/en_list_one_vad_0342.html](http://www.europeana.eu/portal/en/record/9200211/en_list_one_vad_0342.html)
- Princeton Libraries used Leaflet-IIIF for its ["Plan of Versailles"](Plan of Versailles) map. This implementation uses GeoJSON annotation to annotate the map being served out by a IIIF server. [http://rbsc.princeton.edu/versailles/map](http://rbsc.princeton.edu/versailles/map)
- [GeoBlacklight](http://geoblacklight.org/) uses Leaflet-IIIF as the IIIF viewing client for viewing images.
- [Fulcrum.org](https://www.fulcrum.org/) uses Leaflet-IIIF for viewing image resources. See it in action [https://www.fulcrum.org/concern/file_sets/s7526c42w](https://www.fulcrum.org/concern/file_sets/s7526c42w)
- [IIIF Curation Viewer](http://codh.rois.ac.jp/software/iiif-curation-viewer/) - uses Leaflet-IIIF to provide curated cropped viewing experience of IIIF images
- [Digital Typhoon: Himawari-8 Clipping](http://agora.ex.nii.ac.jp/digital-typhoon/himawari-3g/clipping/index.html.en) uses Leaflet-IIIF allowing users to clip sections from a large resolution satellite image.
- [IIIF Curation Viewer with Hentaigana Image Recognition](http://npn-2sc1815j.appspot.com/hentaigana/) Combines [IIIF Curation Viewer](http://codh.rois.ac.jp/software/iiif-curation-viewer) with [TensorFlow](https://www.tensorflow.org/) for character recognition. [Demo](https://twitter.com/2SC1815J/status/805064098207535104)
- [Matthew Paros' Map of Britain](http://bl.ocks.org/mapsmania/raw/6486214d30f8684bd1a0550481138d5e/) is a short story-map that explores some of Matthew Paris' errors and to begin to understand the geographical conception he had of Britain in the 13th Century. The map also includes modern English translations of the medieval place-names.
