[mapserver-users] problem with TRUETYPE and GEOMTRANSFORM 'labelpoly': wrong calculation by mapserver ?

[Oliver Christen]

Hello Steve
I have created a test case and opened a issue:
https://github.com/mapserver/mapserver/issues/4595

as stated in the issue, it is possible the problem is caused by the 
TRUETYPE font itself, but I dont have the knowledge to debug the 
processing inside mapserver to find out.

best regards
Oliver
