MINFEATURESIZE is used only for labeling and makes sense when a polygons are
clipped. It
allows you avoid labeling slivers.

Hi Steve,
Thanks for you promptly reply. I've definitely try label_no_clip
out. However, I don't think the MINFEATURESIZE if for me. The polygon
as a whole is big enough for labeling, the problem is just that it's
sliced into two parts. Having a min size limit on it may render the
label gone at the edge, which is not the desire result.

You can use the label_no_clip (I think that's right) PROCESSING parameter
to force label position to be computed on the untransformed geometry. This
results in a stable position regardless of scale or map extent.
You can also use the label parameter MINFEATURESIZE to limit the size of the
features being labeled. Its value is given in pixel and for polygons its
compared against the narrowest portion of the computed bounding box for the
feature.

Subject: [mapserver-users] Labeling behavior at the edge of image
Hi all,
I've met an issue during my work. There is a polygon right at the edge
of an generated image. By setting position to auto, the label is
rendered, shifted a little bit off. It's as expected I would say.
However, a question arose immediately, what happen to the label of the
other part of the same polygon in the tile right next to this image?
Answer is that it's not render, no label to the other part. It seems
reasonable too. But it does seems a bit odd to viewers, since after
tiles are shown on a browser tile by tile side by side. No one will
notice that there is the edge slicing the polygon right into two
parts, and the label is shifted off from the center of the polygon.
So, if I would like to have the label sits right at the middle
(position cc) of the polygon, then what?
Not sure if it can be achieved. I've tried allowing partial label, but
doesn't seem working. Anyone have any idea?
