Hallo Frank, thanks for your information.
As you recommended I started a gdalinfo on my MrSID files with the following result: the origin MrSID file has a coordinate shift in x direction, that means the image_xy_origin is for example 10000.125/306999.875, but the sdw file has an image origin of 760000.125/306999.875; might there be a problem with the world file ??? how can I make sure, that the coordinate system of the world file is used ???

The zero sized area can easily happen in real use if you zoom in to a fraction of a pixel. Were there any preceeding debug messages, perhaps indicating the window? What is your map view extent? What does gdalinfo report for the mrsid file? gdalinfo is a commandline utility that is part of FWTools - http://fwtools.maptools.org/ Best regards, -- ---------------------------------------+------------------------------------ -- I set the clouds in motion - turn up | Frank Warmerdam, [EMAIL PROTECTED] light and sound - activate the windows | http://pobox.com/~warmerdam and watch the world go round - Rush | President OSGeo, http://osgeo.org _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users
