Re: Oldstyle Figures (OSF) from OpenType Font

2012-04-21 Thread Josiah Boothby
 can anybody tell me if I can use the 'Old Style Figure' subset of an
 OpenType font in markups?

I may be mistaken, but I don't believe there is currently a way to do
this. Perhaps post to the Bugs list as a feature request?

Thanks for pointing to this, Werner.

Just a question:
In the issue report you say, LilyPond doesn't currenty (i.e. Nov 2010) 
support OpenType features.
LilyPond does support ligatures and kerning (at least on Linux, it seems 
this doesn't work on Windows). Are these no OpenType features? Or have 
there been improvements since your report?

You could use a font that defaults to old style figures. For example, 
Spectrum MT:


\relative c'' {
c4^\markup { \override #'(font-name . SpectrumMT SC) 0123456789 }
}

Unfortunately that's not possible because I can't select my font 
according to this.

And it's not a show stopper not to have OSF, just an inconvenience.

I assume such an improvement would be a non-trivial issue?

2012-04-21 Thread Werner LEMBERG

 2010) support OpenType features.

Yes.

 LilyPond does support ligatures and kerning (at least on Linux, it
 seems this doesn't work on Windows). Are these no OpenType features?

Today, kerning is usually realized with a feature, yes.  And having
ligatures certainly is.

 Or have there been improvements since your report?

Features which are activated by default are seen by lilypond also.
For example, handling of Arabic needs a lot of OpenType support, and
this is provided by Pango automatically.

However, we need a mechanism to activate optional features.  And to
answer your question from the other mail: Yes, this is a non-trivial
task to implement.
