Hi,

I'm starting to user PostGIS 2.0 raster and can use in database images ok
but seem to be struggling with out-db / filesystem rasters. With a larger
image i was just getting qgis falling over but with a smaller image i am now
getting back the following:

<http://osgeo-org.1560.n6.nabble.com/file/n5028921/qgisoutput.png> 

The image used is an RGB TIFF without internal tiling and is uncompressed.
Size 400 by 400 px:

<http://osgeo-org.1560.n6.nabble.com/file/n5028921/sourceimage.png> 

I loaded the file using:

raster2pgsql -I -C -r -e -Y -d -R -F -s 27700 C:\rastertest\100mtest.tif
tablename | psql -U username -d database -h localhost -p 5432

I appreciate that this might be down to the gdal PostGIS Raster driver so
i'm also posting there.

Any thoughts on errors i might be making would be great

Thanks

Andy
