lmt_followtext and cycle

lmt_followtext and cycle

[Pablo Rodriguez]

Hans,

I’m afraid that lmt_followtext has problems with cycle again.

 \starttext
 \startMPcode{doublefun}
  path p ; p := (0,0)..(3,3.5)..(9,-3.5)..
    (12,0)..(9,3.5)..(3,-3.5)..cycle;
  draw p xsized TextWidth ;
  draw lmt_followtext [
  text = "\dorecurse{9}{Just random text · } ",
  path = p,
  autoscaleup = "max",
  reverse=true,
  ] xsized TextWidth ;
 \stopMPcode
 \stoptext

Many thanks for your help,

Pablo

You can't expect two overlayed graphics to know of each others 
independent applied scaling. So you need to do this:

  \starttext
  \startMPcode{doublefun}
   path p ; p := (0,0)..(3,3.5)..(9,-3.5).. 
(12,0)..(9,3.5)..(3,-3.5)..cycle;
   p := p xsized TextWidth;
   draw p ;
   draw lmt_followtext [
       text = "\dorecurse{9}{Just random text· }",
       path = p,
       autoscaleup = "max",
       reverse=true,
   ] ;
  \stopMPcode
  \stoptext

Sorry, but version from 2021.03.17 17:46 requires two scalings, in path
and in lmt_followtext:

 \showframe
 \setuppapersize[A6, landscape]
 \starttext
 \startMPcode{doublefun}
  path p; p := (0,0)..(3,3.5)..(9,-3.5)..
      (12,0)..(9,3.5)..(3,-3.5)..cycle;
  draw lmt_followtext [
     text = "\dorecurse{9}{· Just random text }",
     path = p xsized TextWidth,
     autoscaleup = "max",
     reverse=true,
  ] xsized TextWidth;
 \stopMPcode
 \stoptext

To get what version from 2021.03.13 11:22 got only scaling lmt_followtext.

I mean, with previous version only scaling lmt_followtext worked fine.

in one case you scale the result in th eother the text and when the text 
runs outside the shape the resulting bbox is larger than the original

xsized TextWidth scales the result

how can the p you draw know that the lmt_followtext hs scaled to textwidth
