Spam: Re: [UMN_MAPSERVER-USERS] Strange imagetype/outputformat behaviour

[Dejan Gambin]

Frank,

I am using MS4W and p.mapper framework. The request is very simple - I have
a raster layer made by tileindex shape file, like this:

LAYER # raster
  NAME         "ortofoto"
  GROUP	       "ortofoto"
  STATUS       ON
  TYPE         RASTER
  METADATA 
    "DESCRIPTION" "Ortofoto"
  END
  TILEINDEX "vodnjan"
  TILEITEM "LOCATION"
    CLASS
    Name 'ortofoto'
    COLOR 51 102 160
    OUTLINECOLOR 0 0 0 
    TEMPLATE void
  END
END 

Maybe I need to look in the p.mapper somewhere and debug the requests...I'll
try...

regards, dejan
