[mapserver-users] Multiple LabelItems using Mapserver 5.2 and Openlayers

[Karl Suiter]

Hello All,

  I'm using Mapserver 5.2 and Openlayers 2.6 as my map interface.  When
called using Openlayers, Mapserver renders two LabelItems when the layer to
be labels is of type "polygon".  I've sort of fixed this issue by including
PROCESSING "LABEL_NO_CLIP=1" in the Layer definition.

  So, for the most part, it works OK.  But on some generated maps, I still
see one Layer that still renders two Labels.

  I then noticed that if I tweaked the OpenLayers "minScale" value when
defining a new map (see below), I could get suppression of the second label.

   var map = new OpenLayers.Map( 'map', {controls: [], maxExtent: bounds,
restrictedExtent: bounds, projection:"none", minScale: 10000, units: "m" }
);  // change the minScale to 15 to suppress the 2nd label

  I would like to remove the minScale variable from the Openlayers map
definition, but that pesky second LabelItem keeps coming back.

  Has anyone seen/fixed this problem?  Should I create a bug ticket.  FYI -
I am cross-posting to the OpenLayers listserve to see if anyone there has
experienced this problem.

  Here is my Layer definition I've been working with:

  LAYER
    NAME CR01
    STATUS OFF
    DATA cr.shp
    TYPE POLYGON
    CLASSITEM "FIPS_ADMIN"
    LABELITEM "ADMIN_NAME"
    PROCESSING "LABEL_NO_CLIP=1"
    CLASS
        NAME "FIPS_ADMIN"
        EXPRESSION "CR01"
        COLOR 226 166 166 # E2A6A6
        OUTLINECOLOR 32 32 32
          LABEL
            COLOR 0 0 0
            TYPE TRUETYPE
            FONT verdana
            SIZE 10
            ANTIALIAS TRUE
            POSITION AUTO
            PARTIALS FALSE
            MINDISTANCE 300
            BUFFER 4
          END # end of label
      END
  END


Thanks!
