Hi, Maybe the error means what is says and the size of image (256x256 pixels) does not suit any of the supported scales with the given BBOX. WMS-C requests be exactly correct to suit the cached tiles.
QGis and uDig support WMS-C so that they read the GetCapabilities from the service and adjust the GetMap requests accordingly automatically. -Jukka Rahkonen- ________________________________ Lähettäjä: [email protected] [[email protected]] käyttäjän Michael Markieta [[email protected]] puolesta Lähetetty: 31. tammikuuta 2012 20:39 Vastaanottaja: [email protected] Aihe: Re: [mapserver-users] Mapserver and TileCache, parsing error thereby no cached images My data is in WGS84 Major Auxiliary Sphere (as outputted by ArcGIS)..
