[mapserver-users] Problem with "ANGLE FOLLOW"

[Christy Nieman]

Hi,

ANGLE FOLLOW is subject to MAXOVERLAPANGLE (see 
http://mapserver.org/mapfile/label.html). If there is an angle between 
letters that is larger than 22.5 (if you don't have a manually-set 
value), then the label will not be drawn.

I wrote a blog post that may help you understand:
