Leaflet-IIIF Magnifying Glass Example
Raw
README.md

This example uses the Leaflet plugin Magnifying Glass.

The images being shown are multispectral versions of the Martellus map from Yale.

Using Leaflet-IIIF and the magnifying glass plugin, we can quickly provide a multispectral inspection.

Special thanks to Chet Van Duzer for help making this visualization possible. Additional thanks to the Beinecke Rare Book & Manuscript Library for providing these images. And last but not least, thanks to Ben Albritton for his work in accessioning the content and serving the images via IIIF.
