[mapserver-users] Re: Crispness of road edge

[YC Nyon]

Hi,

I've been using the map file from http://boston.freemap.in/basemap.map
to setup a mapserver 5.0 WMS and using Openlayers as the interface.

The results has been good except the edges of the road doesn't seem to be sharp when compared with google or some samples i seen from Mapnik.
I use AGG as the output.
Have tinker with the antialias, width of the line, etc without much luck

Below is snippets of my mapfile:

OUTPUTFORMAT
 NAME 'AGG'
 DRIVER AGG/PNG
 IMAGEMODE RGB
 MIMETYPE "image/png; mode=24bit" 
FORMATOPTION  "INTERLACE=OFF"
