[Mapserver-users] MINSCALE in webobj

[Daniel Morissette]

MINSCALE/MAXSCALE in the WEB object apply to the mapserv CGI only.  In
MapScript you have to handle this check yourself.  

It would probably be a worthwhile enhancement to add an optional flag to
the PHP MapScript zoomPoint() and zoomRectangle() functions to request
enforcing the MINSCALE/MAXSCALE values.  Please add this to bugzilla if
you feel it's worth it.
