Leaflet-IIIF

A Leaflet plugin for viewing IIIF images.

You can find some online examples here : https://sim51.github.io/Leaflet-IIIF/examples/

This project is a fork of http://mejackreed.github.io/Leaflet-IIIF/ It's a complete rewrite of the project with typescript and some enhancements :

• Compatible with all version of IIIF (see server-capabilities.ts file)
• Rotation & mirroring support
• Leaflet toolbar
• Better zoom level nomenclature (level 0 is always the raw image)
• E2E tests

How to install

You need to install this library and its peer dependencies :

$> npm install ow-leaflet-iiif leaflet

How to use it

Import

Package is composed of a css file (only needed for the control), a leaflet layer and a leaflet controler.

For the js part, everything is export in the package entrypoint, so you can do this

import { IIIFLayer, IIIFControl, ...} from "ow-leaflet-iiif";

You can also import just the components you need, they are exposed under the folder ./lib/esm :

import { IIIFLayer, ...} from "ow-leaflet-iiif/lib/esm/layer";

For the css, you need to import the file ./lib/leaflet-iiif.css.

Example

const map = L.map("map", {
  center: [0, 0],
  crs: L.CRS.Simple,
  zoom: 0,
});

const layer = L.tileLayer.iiif("https://ids.lib.harvard.edu/ids/iiif/43183405/info.json", {});
layer.addTo(map);

const control = L.control.iiif(layer, {});
control.addTo(map);
