The ZoomableImages extension allows use of zoomable images using the OpenSeadragon viewer.


Zoomable images reside in the directory: $IP/images/zimages/

OpenSeadragon can be download here: https://openseadragon.github.io/#download

The OpenSeadragon files have to be in a directory called openseadragon that resides in the ZoomableImages directory; the location of the script openseadragon.min.js has to be: $IP/extensions/ZoomableImages/openseadragon/openseadragon.min.js


To install this extension, add the following to LocalSettings.php:

require_once "$IP/extensions/ZoomableImages/ZoomableImages.php";


To add a zoomable image to your MediaWiki installation add the following:

<zoomableimage name="zimage.dzi"/>


The width and height can be specified:

<zoomableimage name="zimage.dzi" width=800 height=600/>

A viewport can be added:

<zoomableimage name="zimage.dzi" viewport='true'/>

The image can be rotated an arbitrary amount:

<zoomableimage name="zimage.dzi" initrotate=25/>
