[Mapserver-users] OGR + DGN STYLEITEM "AUTO" config

[Schepel, Menno]

Frank,

Following your suggestion I left out the CLASS info and added the STYLEITEM
"AUTO". This only results in a blank map! 
However, adding a CLASS definition using a 'dummy' color (255 255 255 or
whatever color you like) gives a good result. Using an empty class (CLASS
immediately followed by END) does not do the trick. So here is an abstract
of the mapfile used:

  LAYER
    STATUS ON
    GROUP DGN
    CONNECTIONTYPE OGR
    CONNECTION "C:\inetpub\wwwroot\vinya\data\xarxa_i07.dgn"
    NAME "Sorea"
    TYPE line
    TOLERANCE 10
    STYLEITEM "AUTO"
    METADATA
      WMS_TITLE "Sorea DGN"
      WMS_SRS "EPSG:23031"
      WMS_EXTENT "420426,55 4591480,93 421308,65 4591676,52"
    END
    PROJECTION
      "init=epsg:23031"
    END
    CLASS
      color 255 255 255
    END
  END

 
Best regards,

Menno

Menno,

In general you should just be able to add STYLEITEM "AUTO" to your layer
definition, and perhaps remove your CLASS definition.  This should cause
MapServer to use the OGR style information.   There should not be any
changes to symbol files required.  I don't think any of the DGN autostyled
stuff uses symbols.

Best regards,
