[Mapserver-users] asymmetric lines

[woodbri at swoodbridge.com]

FYI, there is a bug that I submitted regarding TTF symbols that might 
impact this. See

http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=573

In summary the symbol flips 180 degrees depending on the angle and 
slope of the the line segment.

If you are running into this problem you might want to post a note to 
the list or the bug so we know.

Thanks,
