Free WMF editor
I finally found a way to edit a windows metafile (WMF) graphic as a VECTOR in WINDOWS for free (better yet, Open source).
I won\'t go into the long gory details of the other programs I have tried...
Anyway, what finally worked, was actually installed on my PC before I started looking. It\'s the "Drawing" program in OpenOffice.org\'s package. (I\'m using 1.1, I don\'t know if these features worked in earlier versions)
In Drawing, you can import the .wmf then export it back out. To change it a little bit, you can "convert" the graphic to Vectors and Ungroup the shapes and lines.
I have high hopes that Sodipodi will soon do this... but only time will tell.
