[Mapserver-users] default extent

[Jan Hartmann]

The MS3.7 MapFile doc says under the MAP heading:

-------------------------------------
EXTENT [minx] [miny] [maxx] [maxy]

     The spatial extent of the map to be created. Most often you will 
want to specify this, although mapserver will extrapolate one if none is 
specified.
---------------------------------------

It would be nice if EXTENT had some sort of default, but I always get an 
error-message when I don't specify it:

(msCalculateScale(): General error message. Invalid image extent).

What exactly does this mean?

Jan
