Good evening!
I want to scale a font loaded via the simplefonts so sans and serif have the same x-height. But as soon as I use a font size larger than 12pt, the scaling is somehow off or ignored. Example:
\usemodule[simplefonts] \setupsimplefonts[expansion=quality, protrusion=quality] \setmainfont[Times New Roman] \setsansfont[Arial][scale=0.863] \starttext \setupbodyfont[6pt] 06pt serif xx{\ss xx sans}\\ %fine \setupbodyfont[12pt] 12pt serif xx{\ss xx sans}\\ %fine, too \setupbodyfont[14pt] 14pt serif xx{\ss xx sans}\\ %here it starts to be off \setupbodyfont[16pt] 16pt serif xx{\ss xx sans}\\ \stoptext
Your example is a bit difficult to test here because it's windows-centric, I don't have Arial on my system. But by looking at it, you should have something like this in your file before setting the fonts:
\starttypescript [sans] [default] [size] \definebodyfont [16pt] [ss] [default] \stoptypescript \definebodyfontenvironment[16pt]
and so on for other arbitrary sizes. ConTeXt doesn't define complete environments for every imaginable size (but I imagine Wolfgang may come up with a clever solution within his module).
A clever solution would take a while because in this case i want to change the whole code in rewrite it with all the new mkiv goodies and the spec interface.
A fast solution is also possible but it won’t be more than a fix.
No need to rush from my part. I have what I need (bodyfont in 11.5pt with a properly scaled sans companion). I get the rest of the font sizes with \tfa etc. and that keeps the proportions intact.
