[mapserver-users] AGG Anti-alias & VECTOR sybmol

Greetings!


I've generated a map: http://maps.mapking.com/eg.png

with these:

As you can see in the image, the everything are smooth except the railway.
All line and polygon layers are drawn with "simple" styles without the use
of SYMBOL. Only the railway lines are drawn with a VECTOR symbol.
Does AGG's anti-alias works with symbols?  If not, any work around?
