Hi Cora, Could you prepare a small sample image and put it somewhere for downloading? Or did you already do it in some earlier mail?

I tried PROCESSING "SCALE=AUTO". This method results in a red/white image. All the labels in the map are drawn red (originally black). The whole topographic information in the background is just white (originally many different colors). I tried it with a combination of different outputformat-declarations and processings. Unfortunately I didn't get a correct result.
