[Mapserver-users] Wind Barbs / Truetype font annotation?

[Luke Wallace]

I've been working on the Texas Mesonet project, and am trying to get Wind 
Barb plots for each of the sites based upon their wind speed and direction.  
I've looked through the archives, but the bits of code I've found don't seem 
to work when combined together.  Below are the important parts of my main 
mapfile

SYMBOL
  NAME 'circle'
  TYPE ELLIPSE
  POINTS 1 1 END
  FILLED TRUE
END

SYMBOL
   NAME 'wind1'
   TYPE truetype
   FONT 'Esri_Weather'
   FILLED true
   ANTIALIAS true
   CHARACTER "b"        # symbol number in character map
end

#
# Working Point Layer
#
LAYER
  NAME weather-metar
  TYPE POINT
  DATA currentWeather
  STATUS ON
  LABELCACHE OFF
  TOLERANCE 10
  CLASS
    NAME 'Weather Stations'
    COLOR 100 200 164
    SYMBOL 'circle'
    SIZE 7
    TEMPLATE "weather_refresh.html"
  END
END

#
# Non-working Barb Layer
#
LAYER
  NAME weather-barbs
   STATUS DEFAULT
    TRANSFORM FALSE
    TYPE ANNOTATION
    DATA currentWeather
    CLASS
   	EXPRESSION "([WINDSPD] = 0)"
   	SYMBOL 'wind1'
   	SIZE 25
	COLOR 0 0 0
    END
END

I realize I'm going to need more classes (with more expressions) to get this 
to be a truly correct barb, but I'm trying to take small steps and just get 
any symbol to show.

The following layer in my mapfile puts a single barb in the lower left 
corner of the map. This shows my fontset is set up correctly (right?).

LAYER
    NAME credits
    STATUS DEFAULT
    TRANSFORM FALSE
    TYPE ANNOTATION
    FEATURE
      POINTS 4 696 END
      TEXT 'b'
    END
    CLASS
      LABEL
        TYPE TRUETYPE
        FONT Esri_weather
        SIZE 50
        ANTIALIAS true
        COLOR 0 0 0
        POSITION UR
      END
    END
END
