disable expansion for one single component

disable expansion for one single component

[Thomas A. Schmitz]

Hi all,

for a book I'm typesetting, I use adobe minion and have enabled 
protrusion=pure,expansion=quality in the typescript and then

\setupalign[hanging,hz]

in the main environment. Now it turns out that in one of the 
components/chapters of the book, this messes up the spacing of some 
characters. Is there a way to disable expansion (but not of course 
protrusion) for one single chapter?

Thanks, and all best

Thomas

Put \setupalign[nohz] before and \setupalign[hz] after your chapter.

Ah, that's it! Thanks Wolfgang, precise and quick, as always!

Hi all, Wolfgang,

coming back to a pretty old question because it doesn't appear to work. 
For the book I'm currently typesetting, I had to disable expansion for 
the entire document because it messed up spacing with Greek letters and 
certain accents. Now the question is the other way round: can I enable 
expansion only for certain passages? I'm in the final revision, and 
expansion would help me take care of a few overfull hboxes. But while 
setting \setupalign[hanging,hz] for the entire document does take care 
of those, doing something like

\start
\setupalign[hanging,hz]
blablabla
\stop

doesn't have any effect. Is this possible at all, or am I barking up the 
wrong tree?

Thanks

Thomas

You need to load a font with the expension feature enabled. After that 
you can enable/disable it using setupalign.

Hmm, thanks Hans. How can I test whether this actually works? My 
problem, as briefly as possible: in one component, I get an overfull 
hbox. Turning on hz for the entire product makes it disappear. Turning 
on hz just for this one paragraph doesn't. But I must admit that I don't 
reallt understand the implications of hz etc.

All best

Thomas

The paragraph has to end before the group is closed.

\definefontfeature[default][default][expansion=quality,protrusion=quality]

\starttext \showframe

\input tufte

\blank

\start
\setupalign[hanging,hz]
\input tufte
\stop

\blank

\start
\setupalign[hanging,hz]
\input tufte\par
\stop

\stoptext
