[mapserver-users] Re: Crispness of road edge

[thomas bonfort]

hi,
the output you're showing has been rendered with gd, not agg.
make sure openlayers is calling your wms server with your agg
outputformat, by adding a
format: 'agg'
to your layer options.

ps: the "antialias true" keywords are not necessary when using agg

cheers,
thomas
