I've got an unusual use for OpenLayers. I'm trying to create an image browser for a very large image-- 648000 by 648000 pixels to be exact. This image will be the "rosetta disk" that we are creating. See http://www.rosettaproject.org to check out our project.
My first attempt was to hack the app at: http://www.casa.ucl.ac.uk/software/googlemapimagecutter.asp I created a bunch of image tiles at various resolutions and then was able to Use the Google Maps API to create the browser I needed, EXCEPT that the local javascript calls google.com for support functions. So even though the HTML and javascript are local and the tiles are all local, I still need internet access to view the image. OpenLayers was suggested as a replacement. What I'd like to do is build an image viewer than can run totally locally without more than a web browser (no HTTP). I was hoping there'd be a OpenLayers.Layer.LocalFileSystem class that I could use directly. I can easily slice and dice my tiles to be any size and resolution, and I'm willing to bring in additional javascript libraries. So what should I do? Am I missing something obvious? Should I try to subclass OpenLayers.Layer to use the local file sytem? Any suggestions or pointers are greatly appreciated. Thanks.. Kurt :-) _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users
