[NTG-context] Proper setting of font features for protrusion/expansion
Dear All,
e.g. in the last example at http://wiki.contextgarden.net/Protrusion there
is the following definition:
\definefontfeature[default][default][expansion=quality,protrusion=quality]
I understand it overrides default settings and adds these two features.
In my code I use the following shortcut found somewhere:
\definefontfamily[palatino][rm][Palatino Linotype][features={default,
quality}]
Both features works, but I am not sure if I am getting the best quality.
Is there any description what that '[features={default, quality}]' option
really does?
Thanks, Jan

When you apply features to a font you can set a list of features and all of
them will be applied.
In the example below you can see both methods, the first text uses the new
featurelist
“testfeature” which uses “default” and extends it with “protrusion=quality”.
The second
text applies the two predefined lists “default” and “quality” (which sets
“protrusion=quality”
and “expansion=quality”).
\setupalign[hanging]
\definefontfeature[testfeature][default][protrusion=quality]
\showframe[text][text]
\starttext
\startfont[Serif*testfeature]
\input knuth
\stopfont
\startfont[Serif*default,quality]
\input knuth
\stopfont
\stoptext

\startfont[Serif*default,quality]
Aahh, thanks.
So it is the preset name what confused me here... From my POV the 'quality'
should be replaced with the more specific label. I believe it will enhance
readability the code. I can imagine even 'microtypography' for this kind of
preset.

quality is just a tag for a preset ... on can add his/her own
btw, i have no clue what micro or typography is involved (esp when
excessive values are used) ,,, using that term for a preset would be
rather confusing
