Message-ID: <200009291211.OAA00007@bar.loria.fr> (raw)
I got the example to work, by calling cont-en and mpost
explicitely. Somehow, my texexec has trouble processing it.
Continuing my experiments, I wanted to try positional graphics.
Here is my input file, adapted from the metafun documentation:
\starttext
\startMPpositiongraphic{mypos:line}
path pa, pb, pab ; numeric na, nb;
initialize_box(\MPpos{\MPvar{from}});
na := nxy ; pa := llxy..lrxy..urxy..ulxy..cycle ;
initialize_box(\MPpos{\MPvar{to}});
nb := nxy ; pb := llxy..lrxy..urxy..ulxy..cycle ;
if na=nb :
pab := center pa -- center pb ;
pab := pab cutbefore (pab intersectionpoint pa) ;
pab := pab cutafter (pab intersectionpoint pb) ;
pickup pencircle scaled 1pt;
draw pab withcolor .625yellow;
anchor_box(\MPanchor{\MPvar{from}});
fi;
\stopMPpositiongraphic
\setMPpositiongraphic{X-1}{mypos:line}{to=X-2}
\setMPpositiongraphic{X-2}{mypos:line}{to=X-3}
In a previous section we saw that some \hpos {X-1} {words} were
\hpos {X-2} {circled} and connected by an \hpos {X-3} {arrow}.
As with most things in \CONTEXT, marking these words is separated
from declaring what to do with those words.
\stoptext
The file compiles with cont-en, and the mpgraph file compiles
with mpost, but I get a lot of "special" errors when I try
to produce the PostScript file. Does this example work with
a PostScript output?
Thanks,
Denis
