Help for partial panorama

Does anyone have a way to display a partial panorama (not 360).?

A sample 360 panorama is at http://www.flashkit.com/movies/3D/Pseudo/Panorama-Degrees-9/index.php
that does a complete 360 and direction of the pan is by mouse position.

We have panoramas that we would like to display whereby the image displays from one end to the other and just ‘sweeps’ the image constantly.

There is a display that is Java based at http://www.imageviewer.co.uk/pan4/ that shows what I would like to do… the difference being is that the control would be by mouse position like the first flash example
.

I’ve worked on this for days but haven’t figured out how to do it yet.
I’m new to Flash and I’m learning as fast as I can but I have a long way to go and sure would appeciate the help.
