show bounding boxes

show bounding boxes

[Herbert Voss]

Hello all,
is it possible to get additional frames around words and
the whole line?


\definefontfeature[default][default][boundingbox=frame]

\starttext
»Tee for Two« shows negative kerning.
\input sapolsky
\stoptext

Curious: What kind of applications are you interested in, particularly for  
the framing-the-whole-line case?

I suspect want you want is doable but will take some start|stopluacode  
trickery that is far beyond my pay grade.

In any case, these might be useful tracing features to add to the bag of  
tricks, if they are not already there..

Best wishes

you can enable some tracers:

\starttext

\bgroup
     \showglyphs
     \showfontkerns
     \showmakeup[hbox]

     »Tee for Two« shows negative kerning.
     \input sapolsky \par
\egroup

\stoptext

(I will add a \showmakeup[line] that will mark lines.)

for my students to show how words, lines, paragraphs, and pages
are build with boxes.
