On a related matter, I have discovered that ArcGIS Server default tile cache origin is top left, not bottom left as it is for other cache schemas. Is there any way to tell OpenLayers.Layer.XYZ to work out tiles to request when tile origin is top left? Setting tileOrigin on the map object and the layer property seems to make no difference. Thanks, Robert Sanson

After requsting the tiles from on fly process (not cached tiles) which create the image based on bounds, every things worked fine. -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/256x256-tp5060802p5061409.html Sent from the OpenLayers Dev mailing list archive at Nabble.com. _______________________________________________ Dev mailing list [email protected] http://openlayers.org/mailman/listinfo/dev This message has been scanned for malware by SurfControl plc. www.surfcontrol.com
