[mapserver-users] Re: DGN files Template usage

[Jeff McKenna]

Anwar,

You should be able to follow the instructions in the OGR Howto to add dgn files
to your mapfile (http://mapserver.gis.umn.edu/doc36/ogr-howto.html).  

Also, the doc is currently incorrect in the STYLEITEM AUTO section
(http://mapserver.gis.umn.edu/doc36/ogr-howto.html#binary).  Styleitem Auto
allows you to use the colours and styles already embedded in dgn and mapinfo tab
files.  The doc should say that specifying a CLASSITEM is optional.  I have
updated the doc and committed it in CVS so the changes should be visible soon. 
Here is an example of how to use STYLEITEM AUTO for a dgn file:

  LAYER
    NAME "test_dgn"
    STATUS ON
    TYPE POLYGON
    CONNECTIONTYPE OGR
    CONNECTION "../data/dgn/test.dgn"
    # This enables use of colors and styles from the source file.
    STYLEITEM "AUTO"
    # Define an empty class that will be filled at runtime from the color and
    # styles read on each shape in the source file.
    CLASS
    END
  END  # layer


Hope this helps.

Jeff
