Hi,
I try to vectorise the outlines of a simple map, using "Trace Bitmap".
The bitmap has 2 colors - white background and a 1px black line for the outlines.
When I use "Trace Bitmap", I get a path on both sides of the black line - but I want just one in the middle of the black line. See: http://www.hagoschaos.de/h/freunde/karteG.html
Is there a way?

If I understand correct, what you want is to have the result of tracing consisting of strokes instead of paths. I do not think this is possible.
Here is a kind of workaround: - fill all the gaps in your contour: http://nicubunu.ro/pictures/tracing/karte.svg - use 'Break apart' to get separate paths for each division of your map: http://nicubunu.ro/pictures/tracing/karte1.svg - set Fill to none and Stroke to black: http://nicubunu.ro/pictures/tracing/karte2.svg
It will need *heavy* adjustment for nodes.

Thank you, that helps a lot.
- use 'Break apart' to get separate paths...
Specially this possibility I didn't know at all. Perhaps I can resize the different areas a little, in a way that the border-lines between them are laying one over another.
Thank you.

Or you can use boolean operation: take two paths, one of the entire "continent" and another for a "country", use boolean operations (difference) to cut the "country" from the "continent" and you will obtain two areas with matching margins.

I feel I was not clear enough, this is what I mean: http://nicubunu.ro/pictures/tracing/difference.png
