Is it possible to have something like that with ZoomView ?
http://www.1egal2.com/patrimoine/demo/zoomify/index.php

We've integrated ViewPoint in our software solution and our customers would really want these kind of possibilities. (especially the little image on left top to know which part is being zoomed...)

So can you just answer "Yes " or "No" ?

TIA

AJAX implementation of Zoomify viewer!

The Brain Maps AJAX-Zoomify viewer may be used with your own Zoomify images. It is much faster than Flash-based versions. Try it yourself. Future versions will enable you to add overlays to brain maps (including markers and polylines) and display shadowed "info windows". The Brain Maps API is a free service, available for any web site that is free to consumers.

Yes. You would need to have these things ready:

1. zoomview image ready go go
2. another small thumbnail image placed inside a 2D Layer
3. another 2D layer on top of that 2D layer with the red frame rectangle.

Then you need to set the 2D layer with the red frame rectangle to change its destination pin (dpin) property to move with the mouse on mouse down by swapping the mouse xy coords into the 2D Layer's dpin property using VETScript or JavaScript. Then stop swapping the mouse coords into the 2D layer dpin on mouse up.

Next you would need to transpose the coordinates of the location of the red frame rectangle or mouse over the thumbnail into the pan property of the camera, again using VETScript or JavaScript.

It's all basically completely open to do whatever you want through scripting.
