[mapserver-users] MINSIZE for POLYGON?

[Korbai, Zoltan]

Thanks to all for the answers. I think the "area" is not the solution
because
the size I mean is the zoomed size. On the map the lakes which are only
some pixels large are similar to dirty pixels. So I only want to show them
when they are zoomed in.
