Hi all,
I was testing now a couple of hours, but I can't find the problem. I simply
want to display a shading with a GeoTiff, but it doesn't work.
My XML-Style:
<Style name="raster">
<Rule>
<RasterSymbolizer>
</RasterSymbolizer>
</Rule>
</Style>
My Layer:
<Layer name="shading" status="on" srs="+proj=merc +a=6378137 +b=6378137
+lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m [EMAIL PROTECTED]
+no_defs +over">
<StyleName>raster</StyleName>
<Datasource>
<Parameter name="type">gdal</Parameter>
<Parameter
name="file">/mapnik/data/raster/39_03_900913_hillshade.tif</Parameter>
<Parameter name="format">tiff</Parameter>
</Datasource>
</Layer>
My system:
Debian-linux 2.6.24-etchnhalf.1-686
My map projection is in spherical mercator and so I warped my rasterfile
also to the same srs. With "tiffinfo" on my GeoTiff, I get this info:

My map is still empty. What can I do?
Thanks in advance
