[Inkscape-user] tracing

Hello I have a problem with tracing. I want to trace with centerline so I get a single line which I can edit.

That is not possible with podtrace (or is it?) Autotrace seems te do the job. To get that working with Inkscape I must install Autotrace and its GUI Frontline. But although autotrace has a win binary, I can't find a win binary of Frontline.

Any ideas? Greeting Jos
