Re: [Mapnik-users] mapnik.Raster, satellite data as background?
Hi, Mapnik is not capable of reprojecting images, so you'll need to have a matching projection for your map, your raster image, and you bounding box. In the XML below it looks like you have degrees for your layer bounds - those should be expressed in projected units instead, and the map's srs must match the layer's. -mike.

Re: [Mapnik-users] mapnik.Raster, satellite data as background?
Hello, thanks for that hint. I was using lat/lon values, i think that was my main mistake. I still need to figure out the correct values and reproject the image, that is right and is what i expected. But now i at least get an image... Best regards, Torsten. Am Sonntag, 19.
