[mapguide-users] Zooming to a defined point

[Kenneth Skovhede, GEOGRAF A/S]

It is not a built-in function, so you have to append it.

The easy way is to modify some of the viewerfiles, but that will cause 
trouble on upgrades.

The slightly more difficult way is to register a "map loaded" event. You 
can find code for this in the mail archives.
In the handler, you can retrieve the main frame url by this code:
//Not tested
var openerurl = GetMapFrame().parent.location.href;

You can then parse the url, and look for x/y/scale parameters in the string.
There are plenty free url parsers, if you search for it.

Once you have the data, you can call the ZoomToView function.
