[mapserver-users] LABEL_NO_CLIP seems not working inmapserver 5.4.1

[Rodriguez, Heraldo]

Hey Steve,
           I found what the problem was. It was a silly mistake I made.
	     Some time ago the labels were separated from the polygon in another layer ( the labelling was no good so we provided the centroids to draw the labels) Since they were points ,in that case partials=False was fine.
           I changed partials to true and that solved my problem. I hope this comment can help someone if they face the same problem I do.
 To sum up 
     I use "labelcache_map_edge_buffer" "-10"  at map level
	       PROCESSING "LABEL_NO_CLIP=ON"     at layer level
            Partials=true with labels
 Thanks and regards.

Hi Rodriguez: I did a couple of quick tests and it seems like the directive is
working as intended, at least with some government unit boundary data. Any
chance you could put together a small test case? Perhaps converting some
data to shapefile and whipping up a simple mapfile that shows the problem.

Are others experiencing the same issues?

Hi everyone,
              We have just upgraded from mapserver 5.2.0 to 5.4.1
Our application use OpenLayers, Tilecache with metatiles on, and
postgis.
The label positioning in polygons has improved a lot but now we are
experiencing  label duplication on metatile boundaries.

The layer with the issues is parcelas. We are using
labelcache_map_edge_buffer and LABEL_NO_CLIP=ON .

Has anyone an idea why  this is happening? The labels length varies from
2 to 4 characters maximum .


A fragment of our map is the following 


WEB
    	#	TEMPLATE "set in index.html"
    	#	MINscale 1000
    		MAXscaleDENOM 1550000
		METADATA
			"wms_title"			...
			"wfs_title"			...
			"wms_onlineresource" ... 
			"wfs_onlineresource" ...

			"wms_srs"			...
			"wfs_srs"			...
			"wms_encoding"		...
			"labelcache_map_edge_buffer" "-10"
		END
    		IMAGEPATH "/tmp/mapserver/"
			IMAGEURL "/mapserver/"
  
END

LAYER

			end
			
		END
	END


Any help would be appreciated. Thanks in advance
