# Tracing with xfig to make shapepar command

I'd like to create text/character shaped paragraphs similar to this. I've followed its reference and have been able to make simple shaped paragraphs with it, but I am unable to hand-trace any character (like $e$ or $\gamma$) to any reasonable degree. One of the comments on the reference mentions AutoTrace but that program crashes on any input, even -help. I've also found an online site that can trace and output to a fig file, but all I get is a whole lot of unconnected points and no closed polygon shape. How can I trace/outline a shape (not by hand) in either xfig or elsewhere to make a polygon shape in xfig to then generate a \shapepar command?
