Pixmap symbols and transparent

[Stephen Davies]

Thanks for the feedback.
Here is some more info.

Cheers and thanks.
Stephen

The image I am using is attached.
The symbol file looks like this:

SYMBOL
	NAME 'tree'
	TYPE PIXMAP
	IMAGE "/usr/local/apache2/htdocs/benparts/symimages/tree.png"
END

The mapfile entry looks like this:

    LAYER
      CONNECTIONTYPE postgis
      NAME "cadt"
      DATA "geom from cad"
      CONNECTION "user=scldad dbname=benparts"
      STATUS DEFAULT
      TYPE POINT
      PROJECTION
        "init=epsg:4263"
      END
      FILTER "gtype='T' and client_id=15"
      CLASSITEM "type"
      CLASS
	EXPRESSION "201"
	STYLE
	  COLOR 0 255 0
	END
	STYLE
	  SYMBOL "tree"
	  COLOR 0 255 0
	  SIZE 9
	END
      END


    END
END
