[Mapserver-users] Q: Dynamic Legends

[Jean-Henry Berevoescu]

No. I have, for example, one of the layers with a number of classes 
(say, streets, with
each type of street having its own class). In a certain area, at a 
certain scale, one could
get, for example, only highways. What I want is to have the legend 
showing only the
symbols/definitions for what is actually in the map at a certain moment.
