[texhax] [XeTeX] Stroking a TeX rule in XeTeX

[Zdenek Wagner]

Yes, both in pdftex in xetex the stroke colour and fill colour are
independent. You can even change the rendering mode of text and print glyph
outlines in one colour with a specified line width and fill them with
another colour. It is shown in my article:
Zdeněk Wagner: Tisk obrysu písma v PDF
which is available here: http://bulletin.cstug.cz/bul2013-1.shtml
It is written in Czech but I hope you can find the code.
