second problem

second problem

[Denis B. Roegel]

I am still using the example

\setupoutput[pdftex]
\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

When I launch cont-en, I immediately get an error with \pdflastxpos.
Is this because I have an old version of pdftex ?

Thanks,

Denis

I think Han The Thanh added this positioning feature after 13c. Using
0.14g I have no problem with that file.
(This is not completely true: with shell_escape = f and no mpgraph.2
in this directory tex stops halfway and I have to create a .2 file
manually first [running `echo "end" | mpost mpgraph` was actually
enough].
I would like to see these problems disappearing since this makes batch
jobs impossible. The errormessage:
Randomizer initialized to 1112061263. [MP to PDF mpgraph.1]
! I can't find file `mpgraph.1'.
<to be read again>

Please type another input file name:)

Re: second problem

[Denis B. Roegel]

Ok, I have now installed the TeXlive 5 distribution.
Things are going much better :-)

However, with the file below, I see only one circle,
around "arrow." 

Thanks again,

You have to change (in cont-new.tex): 

\def\insertMPfile#1#2%
  {\ifx\pdfoutput\undefined
     \doinsertMPfile{#1}%
   \else\ifcase\pdfoutput
     \doinsertMPfile{#1}%
   \else
     \doiffileelse{#1}
       {\convertMPtoPDF{#1}{1}{1}}
       {\doinsertMPfile{#1}}%
   \fi\fi}

I hadn't tested it with the inbetween run alternative. This experimental
def of \insertMPfile is slightly faster that the old one since it directly
calls the converter, bypassing the fig mechanism, but the converted does no
file check [since it is supposed to work with latex too I cannot use low
level context file testing]

There is, for those who want more speed the texexec --batch option, which
also baches mpost,

Re: second problem

[Denis B. Roegel]

Hello,

I am not sure that there was a reply for the problem below,
so please forgive me the repost.

I have now the TeXlive 5 CD installed + context from September 21
I think.

There are two problems with the example below:

  1) I have to do 

     texexec --pdf --color test2

     *twice* in order to see a circle and lines

  2) I see only one circle and not three as I expected

The input file and the first execution log are given below.

Thanks,

Denis
