<br>
included you find my patch...It is very specific to my application (using EPSG:31225 austrian projection, and a reference point in the middle of Austria).<br>
I works like this:<br>
<br>
- I choose a point of reference (in EPSG:31255), and add the width and height of the needed print bounding-box as a second point.<br>
- then I project both points into EPSG:3857 (using the proj4-library), and subtract these 2 points to get the widht and height of the resulting bounding-box.<br>
<br>
I have to admin I do not know enough about projections to judge if this could be made simpler...I think this is just symptom-control, there must be a better solution to this.<br>
<br>
Another downside: I have to use the debug-version of GeoExt and not the single file version.<br>
