# [NTG-context] Changing font and font size inside textex

Dear list,

I want to be able to change the font and the font size inside a MPpage. But
if I try to prepend \switchtobodyfont to the text inside textext it doesn't
work. I'm using the following macro to set the font size via h-height:

\starttexdefinition setxheight [#1][#2]
\switchtobodyfont[#1, 12pt]
\scratchdimen=\dimexpr#2\relax
\switchtobodyfont[#1, \cldcontext{tex.dimen.scratchdimen / tex.sp"1ex"
* tex.sp"1em" .. "sp"}]
\stoptexdefinition

But I can't figure out how to use that in MPpage.
Any help would be appreciated.

Sincerely,
Stefan
