you wont need to unclip in the xar I posted, I have done that [it was clipped [clipview] to the area of the page in the program it was made in]

in xara autotrace is 'bitmap trace' but I can never get xara to smooth the lines as well as inkscape which is what I used, but even then some of the edges are a bit rough as I said; vector magic may be better but it's not free
