Ok, I've converted my lat/lons to spherical mercator coordinates using the functions here:
http://trac.openlayers.org/browser/trunk/openlayers/lib/OpenLayers/Layer/SphericalMercator.js#L80 In the tilecache.cfg file, bbox=-10.93, 51.26, -5.21, 55.56 becomes bbox=-1216722.0342011,6667414.2157046,-579974.54695222,7471318.1244976 I also changed the javascript. Now I keep getting all these error messages associated with each tile image: An error occurred: Current x value -903635.966401 is too far from tile corner x -900122.445725 An error occurred: Current x value -981907.483351 is too far from tile corner x -978393.962675 An error occurred: Current x value -864500.207926 is too far from tile corner x -860986.687250 etc. It seems to me there's some sort of rounding error going on. Can't for the life of me figure out what's going on here. Anyone have any tips?
