[Philippe Gondek]

Hi,

I really enjoy mapserver PHP/Mapscript, I find it verry powerfull. The
speed is incredible... I begin now to try to have a powerfull
interface on my web page...

I trued to show a scalebar, but the unit is not Km and the ratio is
not good!!! How to do to have always a scalbar wwith the good ratio???
Is the projection important???

Thank you...
