Now it seems that I have some bias between the scale displayed
by the Web Client and the scale computed by the QGIS Mapserver.
Is there a way to let both have the same notion of pixel
size?
yeah - I saw that as well. The client uses OpenLayers to calculate the
scale. The QGIS Webclient tries to detect the dpi (there is a
dip-detection at the beginning of the intialization - I hope it works)
and forwards the dpi parameter to QGIS server. I don't know the
internals of OpenLayers and QGIS how they calculate their scales. I
checked the print outs from QGIS server - they seem to be on scale on
the printed paper. On screen it is always hard to verify ...
You can open a bug report, but I can't promise that I can provide a
solution. Of course you are also welcome to investigate!
