[oats-sig] Ang: Re: Ang: Re: Ang: Re: wmf to svg conversion

Hi guys, and more thanks for your input!

surely there must be are better tools? Oh well.

Looks like image magick has not improved since 2002 and Robert's
solution was tha good one even back then
http://studio.imagemagick.org/pipermail/magick-users/2002-August/004112.html

Garry et al edit the files in Adobe Illustrator and export to wmf and
SVG. The wmf files need quite a bit of hand correction, probably due
to the very privative facilities of that format. The SVGs need very
little attention.
