[OpenLayers-Users] Make the base layer empty or blank

[Gregor Mosheh]

My approach is to specify an invalid WMS layer.

    var blank = new OpenLayers.Layer.WMS('Blank',
       "/cgi-bin/mapserv", {layers:'blank', format:'image/png'},
       {isBaseLayer:true, displayOutsideMaxExtent:true }
    );
    map.addLayer(blank);
    // now add nothing but overlays

This does generate the pink boxes, but I always suppress those anyway.

OpenLayers.Util.onImageLoadError = function() { };
