[mapserver-users] Symbol sizes

[Fawcett, David]

Expressions should work for any type of data source.  

When you say that it isn't working, what do you mean.  Are you getting
an error?  Are you getting any symbols drawn with a size of 8?  Are you
only getting red dots or blue dots?  

David.

Hi G,

Classitem and expressions are fine when you are using a shapefile but as
I said my data is stored in a MySQL database where these don't seem to
work. 

Here is a copy of the mapfile I tried to use but it still doesn't work!
 
#####################################
# POI layer - points of interest
#
LAYER
     NAME "poi"
     STATUS default
     TYPE point
     LABELCACHE on
 
     CLASS
          NAME "Large fiscal"
          EXPRESSION ([fiscal] < 1)
          STYLE
               SYMBOL "Circle"
               SIZE 8
               COLOR 255 0 0
               BACKGROUNDCOLOR 255 0 0
          END
    END # class
 
     CLASS
          NAME "Small fiscal"
          EXPRESSION ([fiscal] > 1)
          STYLE
               SYMBOL "Circle"
               SIZE 8
               COLOR 0 255 0
               BACKGROUNDCOLOR 0 255 0
          END
    END # class
END # layer poi
#####################################

No classitem need be specified if you use expressions and in fact they
will be ignored if present but as I said this only works with shapefiles
not with MySQL. 

Thanks for your suggestion.

Peter
