Draw (with GDI+) and save as vector image format?

Just wondering how if it is possible to draw onto something, with GDI+, that can then be saved to some kind of vector format?

Thanks

Ok... no good:
A. I want to be able to SAVE as a vector format
B. I want to be able to draw stuff using GDI+ and output it to a vector, not custom functions etc
