Thanks for this nice example (I wasn't aware of this).
But this doesn't really help me with my problem. I guess my example had
too much irritating eye candy, so I made another one :-)
http://www.wuala.com/indiego/public/ConTeXt/pathtest2.pdf
The problem is, that I need direct access to the glyphs path(s), as I
must calculate the offset paths for the sub shadows (umbra/penumbra).
Inkscape has a similar function called "inset/outset path", if I
remember right.
In the example I used a negative offset for the umbra shadow (udistance)
and a positive for the penumbra shadow (pdistance). The original path is
drawn as 'arrowpath'.
The path creating algorithm (based on the Tiller-Hanson alg.) works
quite good so far, but still needs a lot of tweaking. And glyphs have a
wide range of shapes, so they are nearly ideal for testing purposes.
Anyhow, it can't be helped, if 'glyph' is not working. I'll test some
ConTeXt generated PDF glyphs (MPpage) then and see if I can optimize the
manual path creation a little bit.
Best wishes,
Peter
