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

[Arnd Wippermann]

perhaps it's the default map_imagetype in OL for the MapServer request.
 
    DEFAULT_PARAMS: {
        mode: "map",
        map_imagetype: "png"
    },

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


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" <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:
