[Mapserver-users] asymmetric lines

[youssef chamoun]

Hi Stephan,

I really appreciate your reply.
I tried the OFFSET -99 5 but mapserver gave an error and did not display any 
image. I tried to look for the OFFSET word in the documantation but I could 
find it only for the LABEL object. Can you please give me a more detailed 
explanation?

Thank you again for your help
youssef
