[mapserver-users] Border style of polygon

[Havard Tveite]

You could try OFFSET - see http://mapserver.org/mapfile/style.html

"For lines, an OFFSET of n -99 will produce a line geometry that
is shifted n SIZEUNITS perpendicular to the original line geometry.
A positive n shifts the line to the right when seen along the
direction of the line. A negative n shifts the line to the left
when seen along the direction of the line."

style
   color 255 0 0
   width 1
   OFFSET 1 -99
end
style
   color 255 0 0
   width 1
   OFFSET -1 -99
end
