Slightly OT: tracing a bit-map

Sat Jun 19 01:57:45 UTC 2010

My excuse for asking this question here
is that I'm running Fedora 13 with KDE.

I've scanned a house plan as a JPEG,
and would like to convert this for use with qcad.

Can anyone suggest a simple way of doing this?
QCad does not seem to offer any way of tracing
a bit map.
