[mapserver-users] Lost the transparency after a SO Update

[Andrea Peri]

Hi Seth.
I confirm the sintax

      STYLE
        COLOR "#e1cc4f"
        OPACITY 50
        ANTIALIAS false
        MAXSCALEDENOM 5000000
        MINSCALEDENOM 1
      END


Is working.

The opacity is in percent (50 => 50%)
