[OpenLayers-Users] OpenLayers, MapServer Map files and AGG

[Bill Thoen]

I'm just getting started with OpenLayers so I have a lot of questions, 
but I'll try to pace myself.

Anyway I've been using MapServer and I've compiled it with AGG support 
so I can get nice anti-aliased maps, but when I feed a .map file to 
OpenLayers that includes the AGG driver in the OUTPUTFORMAT section, I 
don't seem to get anti-aliasing.

I'm referencing the map file like so:
 var layer = new OpenLayers.Layer.MapServer( "World",
   "http://sandbox/cgi-bin/mapserv";, {layers: 'states world',
   map: '/var/www/html/blt/usa/usa.map'}, {singleTile: true} );

Everything seems to work, except that I get the old jaggy lines that the 
GD driver used to produce. (Also, I'm using Linux FC9, MapServer 5.0.3 
and OpenLayers 2.5).

Am I doing something wrong, or is AGG not supported in OL?

My .map file looks like:
