A couple of years ago I made a gigapixel image showed in HdView where I manually edited the image pyramide to show different information based on the zoom level. This was successful and I believe it would be possible and attractive to do with KrPano. ( maybe its already possible ? )
May it be possible to make overlays, hotspots etc level sensitive ?
If yes, it will be very helpful when authoring this new deep image media format.
