Hello.

Decided to try sample program which uses GetGlyphOutline.

Does this help?

Huw.

Yes, it does. But application (a heavily modified MS glyph sample
from 1993) doesn't show anything. I could send you the source code
if you are interested to fix it.

It won't at the moment.  Currently no driver in the cvs attempts to
use gdi fonts, so the new code is never called.  [working on it].
