[OpenLayers-Dev] tile problem

[Bart van den Eijnden (OSGIS)]

Yes WMS Untiled can be used for this purpose, it will only use a single
tile.

Example:

baselayer0 = new OpenLayers.Layer.WMS.Untiled( "Topografische kaart",
               
"http://intranet.rijkswaterstaat.nl/services/geoservices/basispakket/topografie?",
{layers: 'AAA126,AAA127,AAA134', 'format':'image/jpeg',
'transparent':'true'}, {'numZoomLevels': 7, 'ratio':1, isBaseLayer: true} );

map.addLayer(baselayer0);

Best regards,
Bart
