[mapserver-users] Re: Mapfile multiple CLASSITEM's

[Donatas Malinauskas]

Yes, Sumit, I understand - with few classes I can describe different 
animals, but the problem is that the same PIG in the map should be in 
severel different colours. The column value (eg. big pig - fills white, 
biggest pig - fills yellow, very big pig - fills red and so on) I read 
from data table...Is it possible to fill the same PIG ( in the same 
class) in different colours depending on data column value?

Thanks :)
