Can you take me an example,please?
I'm sorry but I am not very expert.
And after how I can do the request via CGI?

CLASS

  EXPRESSION ([pixel] >= 0 AND [pixel] < 20 )

  NAME XXXX <=== IS IT WRIGHT?

  STYLE

   COLOR 0 255 255

  END

END



Thanks again.

Just add in a NAME parameter inside of each CLASS tag set.  You'll need to request the LEGEND object via CGI or orther method, but the NAME vales are used to describe the Legend Chips in the mapserver output.

      CLASSITEM "[pixel]"





CLASS





  EXPRESSION ([pixel] >= 0 AND [pixel] < 20 )





  STYLE





   COLOR 0 255 255





  END





END





CLASS





    EXPRESSION ([pixel] >= 20 AND [pixel] < 40)





   STYLE





     COLOR 0 255 0





   END





END





CLASS





   EXPRESSION ( [pixel] >= 40 AND [pixel] < 60)

CLASS





   EXPRESSION ([pixel] >= 60 AND [pixel] < 80)





   STYLE





     COLOR 255 127 0





   END





END





CLASS





   EXPRESSION ([pixel] >= 80 AND [pixel] < 100)





     STYLE





      COLOR 255 0 0





     END





   END





CLASS





   EXPRESSION ([pixel] = 100 )





    STYLE





     COLOR 255 123 0





    END





END





END





END







Can I have returned with the image,  the legend that describes the meaning of the colors?





Thanks in advance.
