\em around \placefigure (bug?)

\em around \placefigure (bug?)

[Procházka Lukáš Ing. - Pontex s. r. o.]

[-- Attachment #1: Type: text/plain, Size: 886 bytes --]

Hello,

the \em statement being placed as the first command of a paragraph to flow around a \placefigure seems to SCRATCH the figure instead of to flow around (bug?). See the minimal example:

---

\starttext
   \placefigure
     [left,none]
     {}
     { \startMPcode
         draw (0,0)--(6cm,6cm);
       \stopMPcode
     }

   01234656789 01234656789 01234656789 01234656789 01234656789 01234656789 01234656789

   {\em 01234656789} 01234656789 01234656789 01234656789 01234656789 01234656789 01234656789

   01234656789 {\em 01234656789} 01234656789 01234656789 01234656789 01234656789 01234656789

   \input tufte
\stoptext

---

Best regards

Lukas

\placefigure and \em (again)

[Procházka Lukáš Ing. - Pontex s. r. o.]

[-- Attachment #1: Type: text/plain, Size: 1060 bytes --]

Hello,

sorry for repeating this topic, maybe it's not too attractive.

Please, have a look to the following problem.

I wonder why the behaviour described bellow occurs and how to typeset a paragraph starting with some text enclosed into {\em ...} group inside the "free" area formed (affected) by \placefigure.

---

\starttext
   \placefigure
     [left,none]
     {}
     { \startMPcode
         draw (0,0)--(6cm,6cm);
       \stopMPcode
     }

   This is a normal text -- it flows around the picture on the left side of the page as expected.

   {\em This empathized text starting a new paragraph} should not scratch the picture left.

   When some text contains {\em an empathized text inside the paragraph}, text flows normally as expected.

   \input tufte
\stoptext

---

Thank you in advance.

Best regards

Lukas

You can add a \strut in front of {\em - that’s a usual workaround for  
problems with non-letters starting a paragraph.

The usual workaround is \dontleavehmode.

... Thanks for the answers.

I'm familiar with using \dontleavehmode when needing to keep a figure midaligned; I had no idea that this would be a similar situation (and solution).

Best regards,

Lukas

Re: \placefigure and \em (again)

[Willi Egger]

Hello,

of course I do not have the solution for the underlaying problem. I found out, that you can put a \strut in front of the problematic text and then it comes out ok.
Another point is, that placing the whole text-part i.e. all 4 paragraphs in your example between \bgroup \egroup results in more problems. In this case the tufte-text is also not flowing around the picture.


Kind regards

Willi

{\em xxx ..}

the first x triggers the start of a paragraph but it happens inside a 
group so it has side effects

\dontleavehmode{\em xxx ..}

here the paragraph is started outside the group
