[OpenLayers-Users] Set Bbox of WMS request

[Bart van den Eijnden (OSGIS)]

If you want the BBOX to be exactly the visible part, use ratio 1 and
buffer 0 in the layer options.

So:

var layer = new OpenLayers.Layer.WMS(null, url, {layers: 'foo'},
{singleTile:true, buffer:0, ratio:1});

Best regards,
Bart
