Thanks for the feedback. I do know about Bob Friesenhahn though I haven't
heard from him recently. I don't use ImageMagick, though I have built it a
few times, and I `stole' from its BMP coder when writing libwmf2, and
don't know anything about its SVG support.
The goal of writing WMF -> SVG is cutting out all the intermediate steps,
and hopefully getting better results. Especially since ImageMagick's WMF
coder is based on libwmf, not on the yet-to-be-officially-released
libwmf2, and is not yet fully featured - but correct me if I'm wrong.
Plus, there's abiword to consider, keeping the number of additional
libraries and dependencies to a minimum, which is a bit of a joke with
ImageMagick (though not with a mini-ImageMagick etc. etc. etc.).
libwmf2 links with libpng, zlib, freetype (2); optionally libjpeg;
optionally expat or libxml2; optionally other stuff.

I stand corrected. Happily. I'm fairly new to SVG.
What is the format for inline images?

Their consultation consisted chiefly in propounding and supporting, for
the thousandth time, each his favourite theories.
