[mapguide-users] Zoom to Extents

[David Hequet]

I'm trying do the same thing with the DWF viewer.

If you are using the ajax viewer, look at the "ZoomSelection()" in
"ajaxmappane.templ" file. This method ask the mapagent for the selecion
extents, calculate the scale, then use ZoomToView().
But with the DWF viewer, i found no tricks to reproduce the calculteScale()
method.
