[NTG-context] read out of \tx-value possible?

[-- Attachment #1.1: Type: text/plain, Size: 788 bytes --]

Hi folks,

is it possible to read out the value of \tx (or \txx ... )  for 
calculations if bodyfont and fontsize is given? \the\tx doesn't work.

     \setuplayout[grid=yes]

     \setupbodyfont[libertinus,12pt]
     \setupinterlinespace[1.25\bodyfontsize]

     \starttext

     \samplefile{tufte}\par

     \startlinecorrection
     \setuplocalinterlinespace[12.5pt]
     \placefigure [middle,nonumber]{\tx\midaligned{bla blablabla 
blabla\\ blubdibla blabla bla}}
             {\externalfigure[][height=40mm, width=60mm]}
     \stoplinecorrection

     \samplefile{tufte}\par

     \stoptext

I would like to calculate the setuplocalinterlinespace similar to the 
setupinterlinespace.

Thanks in advance

Thomas

Does \showbodyfontenvironment help?

Thank you, Hraban,

I know this table. But I think it's too complicated for me to extract 
from the source what I want.
If you had written, use this or that command, I could have done 
something with it.
Now I try it this way:

     \setuplayout[grid=yes]

     \setupbodyfont[libertinus,12pt]
     \setupinterlinespace[1.25\bodyfontsize]

      \starttext

     \samplefile{tufte}%\par

     \startlinecorrection
     \switchtobodyfont[10pt]
     \setuplocalinterlinespace[1.25\bodyfontsize]
     \placefigure [middle,nonumber]{\midaligned{bla blablabla blabla\\ 
blubdibla blabla bla}}
     {\externalfigure[][height=40mm, width=60mm]}
     \stoplinecorrection

     \samplefile{tufte}\par

     \stoptext

Greetings and a nice weekend
Thomas

No need to extract the sizes of /tx and /txx at compile time - just use the values that are specified on this page:
