========================================

Experimental Leaflet.js based DZI viewer

========================================

Background

----------

We have a large number of images using the `Deep Zoom Image

`_ format. Unfortunately, the `opensource release by

Microsoft `_ has not been significantly maintained and the

brunt of the modernization has been performed by a single colleague (see

https://github.com/thatcher/openseadragon)

This repository is an experiment using `Leaflet.js `_ to load the

existing DZI image tiles as part of a possible migration strategy to a project with more momentum

and which I'm currently evaluating for related mapping projects as well.

Status

------

* Experiment: http://acdha.github.com/leaflet-dzi-experiment

* Comparison: http://www.wdl.org/en/item/4032/zoom/

Issues & Oddities

-----------------

* Leaflet currently lacks a way to set boundaries for TileLayers, which causes 404s for all parts of

  the viewport outside of the image extents (see https://github.com/CloudMade/Leaflet/pull/401)

* Leaflet assumes that image tiles are all 256x256. The tiles around the edge of the master image in

  our DZI stacks are not constant size and so we have to override the CSS setting the image

  dimensions. It's not clear whether this has a significant performance impact on any particular

  clients.
