[Mapserver-users] polygon lable problem

[Vincent Schut]

Aaron,

I once had the same symptoms so maybe the same problem, which I solved by 
slighly modifying the source code of mapserver. I asked the developers to add 
this to cvs because it really seemed to improve labeling, but I don't know if 
they'd done it, and if not, why. Maybe I should file a bug/feature request on 
this? If one of the developers (Steve, you once mailed that you would check 
the patch) reads this, could you be so kind to answer this?

The proposed patch is in a mail thread of the mapserver-dev list. Search the 
archives of this list for the subject "label centroid alog". You will find 
the patch there, it's quite simple, just a few lines to change. You could do 
it by hand, just remove the lines that start with a minus sign and add the 
lines with a plus sign :-). Or use 'patch'.
For me this change was magick: at once all my labels appeared. Hope it does 
the trick for you too.

Cheers,
Vincent.
