Hello Andreas,
Thanks for your response. I currently have:
MapServer version 4.8.3.
PHP/Mapscript ($Revision: 1.242.2.2 $ $Date: 2006/03/16 21:03:01 $)
GD version 2.0 or higher
I am thinking about upgrading to 4.10 for the
curved label support, but I'll probably wait
until it's out of beta. Any other suggestions on
how I can get this working without upgrading?
Thanks,
Jennifer
