[OpenLayers-Users] Empty Base Layer?

[Lennox Antoine]

You could just use a tile layer that always returns a blank image. Something
like this should work :

var vzl = new OpenLayers.Layer.TMS(
    'test', 'http://google.com',
    {
        getURL            : function(bounds){ return "
http://yourserver.com/blank.gif"; },
        buffer            : 0,
        isBaseLayer        : true,
        numZoomLevels    : 22,
        transitionEffect: 'resize'
    }
);
map.addLayers([vzl]);

Not sure if this falls into your hack category, but it's simply re-using an
existing layer type, so you don't have to create a new one.
