I guess you are using epsg 900913, which is not a good projection for 
measures...Using openlayers geodesic works for measuring, but on the 
server side when generating the image, geodesic is not used
If geoserver doesn't have a "geodesic" support, you don't have many 
choices...

1- implement a geodesic in geoserver.
2- change your map projection for an appropriate one. Not possible though 
if you are using google map

We have the same issue. The workaround is to generate a wms query with 
bbox, scale using another projection thant 900913

[Polluriel potentiel]  [Users] Printing with geoext








Hi,

I have tried most things now to get a solution to my problem that the 
scalebar is at the wrong scale when I export to pdf throught the mapfish 
print module.

The Openlayers measure control is set to geodesic and so is the openlayers 
scalebar. 

I have played with the client projections, config.yaml, geodesic etc...but 
the pdf scalebar is always wrong. How do I find the problem?


can anyone suggest somewhere to look?


yours,

Rob


// map

var d = new OpenLayers.Projection("EPSG:4326");
var e = new OpenLayers.Projection("EPSG:900913");
var f = new OpenLayers.Map("map", {
        projection: d,
        displayProjection: e,
        units: "m",
        maxResolution: 156543.0339,
        maxExtent: new OpenLayers.Bounds(1069506.899621, 6727760.984838, 
1268243.173127, 6945347.635727),
        controls: [
new OpenLayers.Control.MouseDefaults, 
new OpenLayers.Control.PanZoomBar, 
new OpenLayers.Control.ScaleLine({
            geodesic: false
        })]
    });
