IIIF WebGL / Canvas mobile-ready fast viewer powered by OpenLayers

DEPRECATED: no longer maintained. We recommend using OpenLayers instead, which now has support for IIIF out of the box: https://openlayers.org/en/master/examples/iiif.html (to be part of OpenLayers v6)

IIIF viewer from Klokan Technologies is optimized for desktop and mobile devices (iOS, Android), is open-source, free to use and has, compared to other viewers, the following extra features:

• Rotation on client side: pinch with fingers, alt-shift drag with the mouse.
• Drawing tools: polygons, lines, markers — can be used to annotate parts of the pictures.
• Color adjustment: saturation, lightness, etc.
