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,
