[OpenLayers-Users] pdf export: why the request for tile dimensions of 625x458

[Robert Buckley]

Hi,
Problem: I can´t print any tiles coming from geowebcache!
gridset: 900913
System: Linux Ubuntu 10.04 / tomcat6 / Geoserver 2.1.2 

Javscript

// map
var map = new OpenLayers.Map("map", {
        id: 'map',
        projection: new OpenLayers.Projection("EPSG:900913"),
        displayProjection: new OpenLayers.Projection("EPSG:4326"),
        units: "m",
        maxResolution: 156543.0339,
        maxExtent: new OpenLayers.Bounds(-20037508, -20037508, 20037508, 20037508.34),
        numZoomLevels: 17,
        controls: [new OpenLayers.Control.MouseDefaults(), new OpenLayers.Control.PanZoomBar(), new OpenLayers.Control.MousePosition(), new OpenLayers.Control.ScaleLine({
            geodesic: true
        })]
    });

// layer GWC
var layer_topo = new OpenLayers.Layer.WMS("Topographischekarte", "http://maps.zgb.de/geoserver/gwc/service/wms/", {
        layers: 'zgb:tk50',
        projection: "EPSG:900913",
        format: 'image/png',
        transparent: true,
        singleTile: false
    }, {
        'buffer': 0,
        'opacity': 1,
        'isBaseLayer': true,
        visibility: true
    });

Can anyone tell me why the mapfish print is requesting tile dimensions  of 625x458?



Yours with thanks,
