[mapserver-users] Painting outside a polygon.

[Christy Nieman]

Hi,

You can set the IMAGECOLOR parameter for the map (see 
http://mapserver.org/mapfile/map.html), which sets the background colour 
for the map.  Then your coloured polygons would be drawn on top of the 
background colour.

Regards,
