Re: [NTG-context] Setup font size by dimension variable

Hi all,

I want to set the font size by using the dimension variable, but it doesn't work. What am I doing wrong?

\definemeasure[AAA][20pt] \newdimen\BBB \BBB=20pt

\starttext TEXT

% don't work \switchtobodyfont[\measure{AAA}] AAA

% don't work \switchtobodyfont[\the\BBB] BBB

% ok \switchtobodyfont[20pt] TEXT 20pt

\stoptext

Hi Dmitriy,

the size-related arguments to \switchtobodyfont and \setupbodyfont aren’t real TeX dimensions but identifiers for predefined bodyfont sets. Example:

\def\mainfontsize{20pt} \definebodyfontenvironment [\mainfontsize]

\starttext TEXT \switchtobodyfont [\mainfontsize] TEXT 20pt \stoptext
