[Mapserver-users] Transparent GIF polygon fill pattern

[Steve Lime]

If I recall correctly transparency for PIXMAP symbols is not controlled
by the TRANSPARENT flag but by the the transparency of the image itself.
Is  '../images/plqv.gif' a transparent gif?

Has anyone filled a polygon with a transparent GIF? I can get the GIF
to
fill the polygon, but it's not transparent.  Here are some code
snippets:

Symbol file:
 SYMBOL
  NAME 'plqv'
  TYPE PIXMAP
  IMAGE '../images/plqv.gif'
  TRANSPARENT 0
 END

Mapfile:
 CLASS
    EXPRESSION "PlQv"
    NAME "PlQv"
    BACKGROUNDCOLOR 204 179 255
    OUTLINECOLOR 102 102 102
    COLOR 204 179 255
    SYMBOL 'plqv'
    LABEL
      MINDISTANCE 200
      ANTIALIAS TRUE
      FONT "arial"
      TYPE truetype
      SIZE 7
    END     
  END
