Ouch, i'm sorry. I missed that. I've changed the Layer description and also added some more configuration according to this:
http://trac.mapnik.org/wiki/RasterSymbolizer So i also added: <Style name="raster"> <Rule> <RasterSymbolizer> <CssParameter name="opacity">0.8</CssParameter> <CssParameter name="scaling">bilinear</CssParameter> <CssParameter name="mode">multiply2</CssParameter> </RasterSymbolizer> </Rule> </Style> <Layer name="bground_east" 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 +nadgri...@null +no_defs +over"> <StyleName>raster</StyleName> <Datasource> <Parameter name="type">raster</Parameter> <Parameter name="file">/local/vid/earth/land_shallow_topo_east.tif</Parameter> <Parameter name="format">tiff</Parameter> <Parameter name="lox">0.0</Parameter> <Parameter name="loy">-85.0511</Parameter> <Parameter name="hix">180.0</Parameter> <Parameter name="hiy">85.0511</Parameter> </Datasource> </Layer> Hmm, still the image is not shown. I wonder why, i tried several changes, also leaving away the srs entry. Also tried a different (smaller) TIF, tried it at different locations on the map and different extents and also reordered the layers and tried different "mode" settings for the RasterSymbolizer. I've also tried putting the Layer on top of all other Layers. Hmm, just tried and changed the name of the used Style from "raster" to "qweqwe". The whole map still gets rendered, no error is thrown. It seems the DataSource Raster does not use a Style at all, is that right? It looks to me that this contradicts to the description of the RasterSymbolizer in the URL above. The string "raster" only appears as Parameter name="raster" in the osm.xml that i use, but nowhere else. Did i misconfigure something? Do i need to supply a Style in a different way? In the description it is mentioned that no reproject data (yet), so it can't be that e.g. the aspect ratio of the input TIF is incorrect? Thanks for any hints, Torsten. Am Sonntag, 19.
