positiongraphics

positiongraphics

[Hans van der Meer]

First everything is OK and then suddenly I start getting errors in  
(metafun) position graphics:

! Missing `)' has been inserted.
<to be read again>
                    ;
l.118 ...926pt,72.9016pt)--(95.23926pt,72.9016pt);

The  mpgraph.mp file says at this point:

PlainTextArea:=boundingbox((95.23926pt,72.9016pt)--(95.23926pt, 
72.9016pt);
shifted (609.52148pt,476.59792pt));;

What is happening?

I have some further information on the problem below.
It turns out not something with position graphics.
Instead it is a rogue footnote (that is being colored).
It seems that this happens only when the footnote is at a particular  
point on the page;
it is therefore next to impossible to give a minimal example.

With some extra thought what happens seems to be this.

> PlainTextArea:=boundingbox((95.23926pt,72.9016pt)--(95.23926pt,  
> 72.9016pt);

The area above is made and somehow finished with a semicolon.
Then the next part, the shift is put out:

> shifted (609.52148pt,476.59792pt));;

Together making a statement which is correct except for the  
intervening semicolon.
As it occurs only at specificly placed footnotes, it looks like a  
subtle flaw in the footnote background generation.

I would be happy for a solution, because otherwise typesetting text  
with footnotes could become a nightmare.

can you make a minimal failing example? looks like an ; too much

I send the offending mpgraph.mp file. It has ;'s all over. There are  
so many ;;'s and even some ;;;'s that I am tempted to think that one  
of the translation scripts is the culprit, adding a ; per newline  
maybe? I am sorry not having taken a look into the ruby scripts, but  
my ruby knowledge is nihil.

The tex input file would be more useful. The mpgraph file is
autogenerated from that, after all.

I am afraid that isn't possible just now. The problem seems very  
specific in the placing of the footnote (narrow margin of error) and  
after editing my current text it has vanished. It looks like one of  
those erratic problems that tend to occur mostly when one is in a hurry.

Seeing the value of the shift:
> PlainTextArea:=boundingbox((95.23926pt,72.9016pt)--(95.23926pt, 
> 72.9016pt);
> shifted (609.52148pt,476.59792pt));;
and considering I am using pages with a reduced height, I suspect  
this is just about equivalent to 1 \textheight. But the point is that  
inside a metapost statement "boundingbox ... shifted ..." a ";" has  
appeared and that cannot be good.

Sorry not having a minimal example at hand at the moment. When less  
pressed for time I will do some experiments with changing pagefill (I  
guess best done by placing rules of varying height). Surely I will  
contact again if I found such an example.
