Hi,

sorry for the late reply, kinda lost track of this...

That would be normal as pango.Context and pangocairo.CairoContext are
different animals.

Now for the good news, from
http://developer.gnome.org/doc/API/2.0/pango/pango-Vertical-Text.html
  - Since 1.16, Pango is able to correctly lay vertical text out.
  - Note the Gravity stuff

Download
http://svn.gnome.org/viewcvs/pango/trunk/pango-view/test-mixed.txt?revision=2222
then run (with pango 1.16 or newer):
  - for vertical layout (see vertical.png for output):
     pango-view --gravity=east ./Desktop/test-mixed.txt --rotate -90 --margin 60 --markup

  - for horizontal layout (see horizontal.png for output):
     pango-view --gravity=south ./Desktop/test-mixed.txt --margin 60 --markup

Looks good, huh :)

Except, for the bad news: I'm not sure pygtk wraps that part of the
pango api yet (the gravity stuff). At least, I didn't find them in the
.defs/.override files in trunk svn. Anyone have a clue about this?

mvg,
Dieter
