[Mapserver-users] polygon lable problem

[Steve Lime]

Can you share the data? Concave layers are generally not a problem.
Polygon labeling uses a technique similar to scanline conversion used to
compute label points so label points are gauranteed to be "in" the
polygon. Could be an issue with clipping, or perhaps the label cache
(you could test that by setting LABELCACHE OFF), but there's no way to
know without the  data and an extent that shows the problem.

I'll be out until the 14th but will look at it then. BTW What version
are you using?

There is a label item but I am overriding the with a TEXT Cool/Wet in
the class. This is not the first time I have had this problem with
labeling.

  Aaron -

  Have you checked the attribute table for the data layer, and are you
SURE that there is indeed a label string for that polygon?

    With the layer below, Mapserver seams to have a problem labeling
concave polygons. If you look at the image link below, there is one
concave polygon in Canada that is not labeled. Is there any way to get
mapserver to label the polygon.
