Has anyone implemented google maps style navigation arrow (pan left, right, up, down ) any code to share ?

@macarthy None that I know of. Might make a good plug-in.
Shouldn't be too hard...just a viewport.panBy modulated by the zoom level

Greetings from the ChronoZoom project! Bill Crow and I are trying to resurrect the original Silverlight DeepZoom version of ChronoZoom made by the Live Labs team (Quick video: http://youtu.be/tLY8hzSLoaE?t=23s)

It is a collection comprised of 5 large deep zoom images used to represent all of time on a linear scale from 13.8 billion years ago to the present.

I was reading on the OpenSeadragon project page that layout support for collections is a work in progress. I am wondering if anyone would be available to discuss the feasibility of using OpenSeadragon to bring the original version of ChronoZoom back to life.

@saekow Cool! That's a neat project. We've actually recently merged the collections support into OpenSeadragon master, so I'd say it's ready to work with (even if it hasn't been officially released yet)
Let me know if you have additional questions...I'm happy to help

Here is a demo of the collections stuff: http://iangilman.com/osd/test/demo/item-animation.html
btw, we don't yet actually support the DZC format...you'll just have to give a list of DZI's and specify their positions. That's easy enough, though

Hi Ian, cool demos. About the position, how specific can it be? Here is the question in some more detail:

@saekow Absolutely. Just add the underlying image first and then the second image will appear on top of it (i.e. z order is based on image index in the list). Image position is on an arbitrary coordinate plane. For image one you could say its x is 0 and width is 10, and image 2 has x of 9 and width of 1 (or whatever you like)
