(please somebody correct me if Im wrong) But there is another pretty elegant solution you can make: There are several events you can hook on, and change desired parameters before sending them to print. This is what i was doing: Define two more parameters for layer, such as printUrl and printLayerName ie: var WMSLayer = new OpenLayers.Layer.WMS('WMSLayerName', WMSService, { layers: 'WMSLayerName', format: 'image/png' }, { singleTile: true, ratio: 1 }, { isBaseLayer: false, visibility: false, displayInLayerSwitcher: false, printUrl: GeoserverWMS, printLayerName: }); and then just hook onto encodeLayer and change required parameters there. Heres an example: printProvider.on({ 'encodelayer' : function(provider, layer, encodedLayer){ if(layer.printUrl){ encodedLayer.baseURL = provider.getAbsoluteUrl(layer.printUrl); if(layer.printLayerName){ encodedLayer.layers = [layer.printLayerName].join(",").split(","); } } return encodedLayer; } }); Let us know if it worked! > 2. It is possible to print Google layers? I've set my config.yaml according > to the sample here: > http://trac.mapfish.org/trac/mapfish/browser/print/trunk/samples/configNonPremiumGoogle.yaml, > but the result is still a blank white page. > I'm using Google API v3, if it counts. > Looking into I dont see google encoder still, so I dont think this is possible (pleae correct me somebody) > 3. I wasn't able to use the POST method in the printprovider, the request > does not contain POST parameters, however GET works just fine. > var printProvider = new GeoExt.data.PrintProvider({ > //method: "POST", > method: "GET", > url: "proxy.cgi?url=http://localhost:8080/geoserver/pdf";, > autoLoad: true > }); I didnt have any problems with POST (actually when config object gets bigger this is the only method you should use). Maybe some proxy problems? Hope this helps, Cheers > > Cheers, > Attila > > _______________________________________________ > Users mailing list > [email protected] > http://www.geoext.org/cgi-bin/mailman/listinfo/users > > -- Ivan Grcic _______________________________________________ Users mailing list [email protected] http://www.geoext.org/cgi-bin/mailman/listinfo/users
