Re: [mapserver-users] Problem with ANGLE FOLLOW
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: http://research.dmsolutions.ca/2011/new-and-exciting-in-mapserver-6-0/ Christy On 12/03/2012 09:07 AM, umn...@hydrotec.de wrote: Try lowering the BUFFER number? ...

Re: [mapserver-users] Problem with ANGLE FOLLOW
I have updated the documentation for 6.2 by including a reference to MAXOVERLAPANGLE in the description of ANGLE FOLLOW.

Re: [mapserver-users] Problem with ANGLE FOLLOW
@Christy Nieman and @Olivier Courtin: Thank you very much! This solved the issue. I tried MAXOVERLAPANGLE shameless big number and all labels were drawn. We'll read the blog to find a reasonable solution.
