Thanks for your help. That's already better. The base font size, and the bigger
sizes are correct now. But it still does not work with the smaller sizes:
% ---------------------------------------
\setupbodyfont[10bp]
\definebodyfontenvironment
[10bp]
[xx=7bp,
x=8.5bp,
a=11.75bp,
b=15bp,
]
\starttext
{\tfxx Smallest } % => expected 7pt, actual 6pt with LM Roman 7
{\tfx Small} % => expected 8.5pt, actual 8pt with LM Roman 9
{\tf Normal} % => expected 10pt, ok
{\tfa Larger} % => expected 11.75pt, ok
{\tfb Largest} % => expected 15pt, ok
\stoptext
%-------------------------------------------------------
Maybe that's an issue with optical sizes?
Best,
Denis
