textext funny error

textext funny error

[David Arnold]

Hans, Taco, et al,

I have a funny error involving textext. If I do two compiles of the  
following code, saved a junk6.tex, with:

texexec junk6
texexec junk6

This produces a file junk6.pdf that looks as it should.

However, if I compile the junk6-mpgraph.mp that is produced with the  
above runs, I get:

(/usr/local/teTeX/share/texmf.local/metapost/context/base/mp-core.mp)
 >> unknown picture p
 >> textext.rt
! Equation cannot be performed (unknown picture=numeric).
<to be read again>
                    (
create_axes->...pt;save.p;picture.p;p:=textext.rt(
                                                    
(TEXT8));p:=p.shifted(1.05...
l.148 ...max,ymin,ymax,width,height)("$x$")("$y$")
                                                   ;
?

Very perplexing. Any comments? Helpful corrections?

Here's the file:

%output=pdf

\startMPinclusions

vardef create_axes (expr l,r,b,t,wid,ht) (text xlbl,ylbl) =
   save ux, uy; numeric ux, uy;
   (r-l)*ux=wid; (t-b)*uy=ht;
   textextoffset:=3pt;
   save p; picture p; p:=textext.rt(xlbl); p:=p shifted (1.05*r*ux,0);
   save q; picture q; q:=textext.top(ylbl); q:=q shifted (0,1.05*t*uy);
   drawdblarrow (1.05*l*ux,0)--(1.05*r*ux,0);
   draw p;
   drawdblarrow (0,1.05*b*uy)--(0,1.05*t*uy);
   draw q;
enddef;

texexec --mptex junk6-mpgraph.mp

You need:

   mpost -mem=metafun junk6-mpgraph

Cheers, Taco

Hans, Taco,

Of course. Thanks.
