Hi,
ConTeXt already passes quite a few length parameters on to embedded
MetaPost code ... BodyFontSize, CurrentWidth etc.
Would it be possible to add some more font/math related parameters to
the default definitions? I'm thinking of exposing math OpenType
parameters like
AxisHeight
FractionRuleThickness
UpperLimitBaselineRiseMin
UpperLimitGapMin
LowerLimitGapMin
LowerLimitBaselineDropMin
etc.
of the surrounding text to MetaPost as well. This would be very handy
for me since I need to draw diagrammatic expressions to be used in
formulas and I'd like them to adapt to the current math font and
fontsize automatically. At the moment I set these variables manually...
Also, is there a way to directly get the glyph outlines of, say, $
\bigotimes$ in MetaPost code and use it to derive some length unit
from it?
Oliver
