There is one more thing! when i activate the imageformat "JPEG" in the
Layersection (see below) then the ka-map display only a black image over the
whole mapscreen!
If i change it to an other value like PNG24, nothing get loaded.
i´m completely lost now! does anyone have a solution or is there some
developer who can help me?
thanks
