MapServer CGI : Url encoding of negative values for mapext parameter ?

[Ed McNierney]

Laurent -

Well, as I suspected, your first problem is that you're reversing the min and max X values.  If your minimum longitude is -10 and the maximum is -20 (to the west of -10) you'll get nothing.

Thanks for your answer, Ed, the problem is that i don't know how to write an url with negative values in the extent. No one of these works :

http://localhost/cgi-bin/mapserver.exe?mode=map&map=my_path_to_mapfile.map&mapext=-10+50-20+60
http://localhost/cgi-bin/mapserver.exe?mode=map&map=my_path_to_mapfile.map&mapext=+-10+50+-20+60
http://localhost/cgi-bin/mapserver.exe?mode=map&map=my_path_to_mapfile.map&mapext=-10%2050-20%2060
http://localhost/cgi-bin/mapserver.exe?mode=map&map=my_path_to_mapfile.map&mapext=%20-10%20+50%20-20%20+60

Sorry if it's a trivial problem :-/, i'm always getting this result :

loadForm(): Web application error. Not enough arguments for mapext.

Thanks for your help !

Laurent
