[Geomoose-users] Need label opacity independent of vector layer

[Jim Dahl]

Brent, and all, thanks for the inputs.  I have learned there are several
ways to try get something done.  The easiest for me was to use one entry
in the mapbook with opacity 100% and in the mapfile it points to add one
line in the geometry layer that sets the opacity to 20% and leaves the
text alone.  This was just what I was looking for!

I'm not sure I understand.  My thought was to have one (and only one)
entry in 
the mapbook points to one mapfile with two LAYER entries (one with a
CLASS NAME 
and the other with a CLASS but no NAME).

Anyways, it turns out you only need on LAYER in your map file.  The
OPACITY 
setting only applies to the feature's geometry STYLE, not the LABEL!
Personally 
I consider this a bug in mapserver.

So this works (no OPACITY applied to LABEL, 20% on geometry):

   LAYER
     NAME 'Urban'
     TYPE POLYGON
     DUMP false
     DATA 'G:/GeoData/Parcels/Alberta/t_carsta.shp|layerid=0'
     METADATA
       'ows_title' 't_carsta'
       'identify_record' 'parcels_identify.html'
     END
     STATUS OFF
     LABELITEM 'PID'
     OPACITY 20        # Geometry only!!
     CLASS
       NAME 'Urban'    # show in legend
       STYLE
         SYMBOL 0
         SIZE 7.0
         OUTLINECOLOR 0 0 0
         COLOR 255 255 242 # 222
       END
       LABEL
         FONT arial
         TYPE truetype
         SIZE 8
         COLOR 80 80 80
         OUTLINECOLOR 255 255 255
         POSITION cc
         ANTIALIAS true
         PARTIALS true
       END # Label
     END # Class
   END # Layer
