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  ENDEND
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.

              Hi,            
            
              
                I have a file.map like this:              
            
            
                            
MAP
            
   NAME"distribution"
          
   CONFIG  "PROJ_LIB" "/usr/share/proj/"
        
   STATUS ON
      
   SHAPEPATH "./"
    
   PROJECTION
  
      "init=epsg:4326"

   END

   CONFIG  "MS_ERRORFILE" "/tmp/mapserver.log"

   DEBUG 5

 LAYER

      NAME "tif"

      DATA "/var/www/tmp/a5e1ddfb-6dec-40d0-94e1-ded12f41397e/out/distribution.tiff"

      STATUS DEFAULT

      TYPE RASTER

      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)

   STYLE

    COLOR 255 255 0

   END

END

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.
