Hi Hans and List,
>> 2) Can I tell \connectboxanchors to use my MetaPost code and pass key=value pairs like I do with \setMPpositiongraphic?
> see attached ... the 'cross pages' feature is in the upcoming
This indeed passes key=value pairs, but I cannot get it to pass mine. Is there some intermediate step? Your example has a key=value pair in \connectboxanchors and which is accessed in the MetaPost code. The pair, and MetaPost code are:
rulethickness=1pt
mpvard “rulethickness"
However, if I change the pair and MPcode to (see attached example for full code)
myrulethickness=1pt
mpvard “myrulethickness"
it doesn’t work. Similarly, you have a pair and MPcode that don’t match.
rulecolor=darkgreen
mpvars "linecolor"
This may be a historical fluke, but it suggests that there is some intermediate translation that I am missing. Any way I can name and pass by own key=value pairs?
Thanks!
Gavin
