font features in XeTeX

font features in XeTeX

[Robert Zydenbos]

Dear ConTeXt folk,

Is there any simple way to pass font features as a parameter to
XeConTeXt? i am thinking of things like what in LaTeX would be (between
square brackets) "\setromanfont [AutoFakeSlant=0.5, AutoFakeBold=0.5]
{Doulos SIL Phon}".

There has to be some way to do this, but I seem unable to find it in the
documentatioin I have.

you can just append the directives to the font names (see type -xtx.mkii 
for examples). I don't know if AutoFakeBold is some built in feature. Is 
there a reason why you can't use mkiv with luatex?

I would like to, but I need to use TrueType fonts for Indian scripts in
my work that are supported in XeTeX but not (yet) in LuaTeX.

As an experiment, I tried to use the so-called 'long s' in a Fraktur
font, which comes out well in XeTeX with LaTeX, but I must be doing
something wrong in ConTeXt.

Robert

Example:

% The 'StylisitcSet 11' in the font UnifrakturMaguntia should contain
the so-called 'long s'.
% Somehow it doesn't work.

\starttext

\definetypeface [hauptfont] [rm] [Xserif] [Charis SIL]
\definetypeface [schoenfont] [rm] [Xserif] [UnifrakturMaguntia]
[default] [features={StylisticSet=11}]

\switchtobodyfont [hauptfont]
Dies ist mit Features, denke ich.

{\switchtobodyfont [schoenfont] Und jetzt schreiben wir etwas in
Fraktur, das ist ja schöner.}

\stoptext

Below is a MkIV example where I enabled the Stylistic Set 11 for the 
Fraktur font.

\definefontfeature [longs] [ss11=yes]

\definefontfamily [hauptfont]  [rm] [Charis SIL]
\definefontfamily [schoenfont] [rm] [Unifraktur Maguntia] 
[features={default,longs}]

\setupbodyfont[hauptfont]

\starttext

Dies ist mit Features, denke ich.

{\switchtobodyfont[schoenfont]Und jetzt schreiben wir etwas in Fraktur, 
das ist ja schöner.}

\stoptext
