Re: [NTG-context] Specifying font size as x-height

28 May 2022


      One slight problem is when I use 2\measured{xheight} as the font size I get
an error. \measure works fine though.

How would one specify the font size in LMTX, but via x-height?
You could try this:
\starttexdefinition setxheight [#1][#2]
         \switchtobodyfont[#1, 12pt]
         \switchtobodyfont[#1, \cldcontext{tex.sp"#2" / tex.sp"1ex" *
tex.sp"1em" .. "sp"}]
     \stoptexdefinition
Demo:
\starttexdefinition setxheight [#1][#2]
         \switchtobodyfont[#1, 12pt]
         \switchtobodyfont[#1, \cldcontext{tex.sp"#2" / tex.sp"1ex" *
tex.sp"1em" .. "sp"}]
     \stoptexdefinition
\define[1]\sample{%
         \setxheight[#1][10pt] Hello%
     }
\setuppapersize[letter, landscape]
\starttext
         \dontleavehmode\rlap{\vrule width\textwidth height 10.5pt depth
-10pt}%
         \processcommalist[modern, pagella, termes, heros, bonum,
scholas, adventor, cursor, chorus, dejavu]\sample
     \stoptext
This is kind of a hacky solution though. It works reasonably well,
although there's likely a better (perhaps builtin?) way to do this.
