Hello,
It took me way too much time to trace the source of the problem, but
now I've finally found it, although I don't know how to solve it. It's
not crytical, but for some longer graphics metapost complains about
too long lines.
Assume the existance of the following file, say, a.tex:
\startMYgraphic[1]
draw fullcircle scaled 3cm;
draw fullcircle scaled 3cm shifted (2cm,0);
\stopMYgraphic
The main file contains:
\def\processMYfile[#1][#2]{%
\def\startMYgraphic
{\obeyMPlines % <- problem
\dosingleargument\dostartMYgraphic}
\long\def\dostartMYgraphic[##1]##2\stopMYgraphic
{\startreusableMPgraphic{#1 ##1}##2\stopreusableMPgraphic}
\readlocfile{#2}{}{}
}
\processMYfile[X][a.tex]
\reuseMPgraphic{X 1}
If I leave the \obeyMPlines there, I get spurious characters (probably
because TeX adds some character codes which correspond to \r or \n).
If I comment out the \obeyMPlines it works OK, but longer graphics
fail.
Thanks a lot,
Mojca
This is another, only partially related question, and still only of
theoretical nature:
Also, sometimes it fails because of TeX memory limit exceeded. (If
gnuplot wants to draw a 100x100 grid, it needs 10.000 lines of code
times three - one for color, one for shape, one for actually
drawing/filling it, that makes it some 31.000 lines of code, and TeX
cannot handle that. Will there be any possibility for a solution to it
any time in the future except fixing gnuplot itself? It's not that
important, but I would just like to know if that issue is solvable at
all from within TeX or not.)
Otherwise, the speed of gnuplot doesn't cause any problems any more. I
don't know what has changed, but I bet that ConTeXt now works at least
five times faster with graphics than it worked two years ago for plain
text only ;)
