Polylines to GraphicsPath...then to WMF?

I know how to get my polylines into a GraphicsPath, but how would I save this to a WMF, EMF, or other Vector-based format? Any ideas?

Not bad example how to create metafiles:

Hi, I know this message is old but I try to do the same thing and I was wondering if you can share how you transformed an emf/wmf to a graphicspath?

We don’t even try to transform metafiles to a graphicspath.

Aspose.PowerPoint uses standard API (Metafile classes) to work with emf and wmf files.
