[MapServer-users] LABEL wrap, maxlength oddity

[Jeff McKenna]

Hi Scott!

This might be from our more strict checks in MapServer >= 8.  I tried 
the msautotest for wrap ( 
https://github.com/MapServer/MapServer/blob/main/msautotest/renderers/labels-wrap.map 
), and if I set "MAXLENGTH 0" I get your error (I do see in the docs a 
hidden line of "must be greater than zero", which is odd because above 
that in the docs it explains the case for "maxlength = 0").

If I comment out the MAXLENGTH parameter completely, it wraps at the "|" 
character as expected (please also try that for your mapfile - does that 
solve it?).

In other words, maybe I just need to update the docs, to not set 
maxlength, if you want to wrap at the wrap character.

Thoughts?




thanks,

-jeff
