[Mapserver-users] invalid image extent with dhtml demo and germany map

[Inge Keckeisen]

Hi,

since I try to show a map of Germany with the dhtml interface of the Itasca
demo the scalebar shows the wrong scale (after zooming in a lot) or doesn't
appear not at all. 
The original Itasca dhtml demo is working fine.Also my own mapfile runs well
but only without the dhtml interface.

This is what the browser brings up when right-clicking on the scalebar icon:
	msCalculateScale(): General error message. Invalid image extent.
	msCalculateScale(): General error message. Invalid image extent.
	mapserv(): Web application error. No way to generate map extent.
Maybe I have to change something in the mapserv.js to define the map extent
but don't know what I should do explicitly. I hope someone can give me a
hint.

Regards,
Inge Keckeisen

Here are some snippets of the mapfile:
