[Mapserver-users] Extent units

[Mario Servin]

Thanks everybody!.
    I use the extents as the shpinfo.exe output and it was OK. I succesfully
generate images with POLYGON type. Now, I face another problem and  I cannot
generate any image when I use a POLYLINE. The error message is:
"msDrawShape(): General error message. Only polygon shapes can be drawn
using a POLYGON layer definition. "
     The docs says POLYLINE does not exist as a type so I am not sure how to
manage it.
     Regards,
                    Mario
