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.

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? _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
