[Mapserver-west] Displaying DGN files

[Chris Clements]

Hi All,

i am trying to display a DGN file in MapServer, but am not getting anything
to show up.  This is a DGN v.7 file and contains lines on level 46.  My map
file is pasted below.  There are no errors reported when I call it through
Internet Explorer, a mapserv -v on the my version of MapServer (4.2.3 on
Windows XP Pro) shows Input=OGR.  I can look at the information regarding
the dgn file using OGRINFO (that is where the extents came from), but when I
call the map file through Internet Explorer, all I get is a blank image
returned.  If I change the IMAGECOLOR to something like 200 200 200, it does
show the extent as a gray box, so it is reading the MAP file.  The dgn
projection is NAD 83, UTM Zone 10.

Is there something that I am missing?

Thanks for any help,
Chris
