c4l, I was reminded earlier this week at DLF (and a few minutes ago by Tom and Simeon) that I hadn't ever announced a project I've been working for the least year or so to this list. I showed an early version in a lightning talk at code4libcon last year. Meet Loris: https://github.com/pulibrary/loris Loris is a Python based image server that implements the IIIF Image API version 1.1 level 2[1]. http://www-sul.stanford.edu/iiif/image-api/1.1/ It can take JP2 (if you make Kakadu available to it), TIFF, or JPEG source images, and hand back JPEG, PNG, TIF, and GIF (why not...). Here's a demo of the server directly: http://goo.gl/8XEmjp And here's a sample of the server backing OpenSeadragon[2]: http://goo.gl/Gks6lR -Js 1. http://www-sul.stanford.edu/iiif/image-api/1.1/ 2. http://openseadragon.github.io/ -- Jon Stroop Digital Initiatives Programmer/Analyst Princeton University Library [log in to unmask]
