[OpenLayers-Users] map doesn't draw when width expands beyond 1000px (aprox)...

[Bart van den Eijnden (OSGIS)]

John,

Mapserver by default can only handle images of 2048 by 2048 pixels. Probably
OpenLayers is requesting something larger.

I ran into this as well, you could solve it by either a recompile of your
Mapserver, or you can change your OpenLayers code to use a ratio of 1.

            map.addLayers([layer]);            var layer = new
OpenLayers.Layer.WMS.Untiled( "WorldPOI",
                "http://www2.dmsolutions.ca/cgi-bin/mswms_world?", {layers:
'WorldPOI', 'format':'image/png', 'transparent':'true'}, {'ratio':1,
isBaseLayer: false} );

Best regards,
Bart
