Placing figures flush right and captions in the margin

Placing figures flush right and captions in the margin

[Christoph Redecker]

Hi,

I want to place my figures flush right, so that they are aligned with 
the right border of my text area. Captions should be in the right 
margin, flush left, ragged right. It is a one-sided document.

I've tried

\setupfloats[
	location=right]
\setupcaptions[
	location=rightmargin,
	align=flushleft,
	headstyle=\tfx,
	style=\tfx]
\usemodule[tikz]
\starttext
\placefigure{Test figure caption with a pretty long text which might 
eventually require a line break.}{
	\starttikzpicture
		\draw (0,0) rectangle (2,2);
	\stoptikzpicture
}
\stoptext

and the figure is placed left, and no caption is shown. When I remove 
location=rightmargin, the caption is visible. Other settings I've tried:

outermargin - invisible
righthanging - invisible
right - caption is typeset in the gap between text and margin

I found this old thread:
http://archive.contextgarden.net/message/20090707.065101.8175a86c.en.html, 
but it is not very enlightening.

I'm taking the options from http://pmrb.free.fr/contextref.pdf. My 
ConTeXt version is 2011.06.11.

How can I place figures flush right?
How can I place the captions in the right margin?

Regards

Christoph

Considering the overall activity on the list since I posted the 
question, can I assume that these options simply have not been 
implemented yet?

Hello Hans,

I now checked details.pdf, but I can only find (many!) placement options 
for placing figures - not for the captions. I also noticed that the wiki 
command reference does _not_ list the following options for \setupcaptions:

left middle right lefthanging righthanging leftmargin rightmargin 
innermargin outermargin

They _are_ included in the pdf command reference (ref-en.pdf) dated June 
13, 2011.

Regards

Christoph

This won’t help because it’s ConTeXt’s fault.

This is a quick fix for strc-flt.mkiv but the leftmargin etc. keys are
then ignored when the caption is placed in the margin.

%\def\locatefloatbox
%  {\alignstrutmode\zerocount
%   \shiftalignedline
%     {\floatparameter\c!leftmargin }{\floatparameter\c!rightmargin}%
%     {\floatparameter\c!innermargin}{\floatparameter\c!outermargin}%
%   \alignedline{\floatparameter\c!location}\v!middle}

\def\locatefloatbox
  {\alignstrutmode\zerocount
   \doifnotcommon{\floatcaptionparameter\c!location}{\v!outermargin,\v!innermargin,\v!leftmargin,\v!rightmargin}
     {\shiftalignedline
        {\floatparameter\c!leftmargin }{\floatparameter\c!rightmargin}%
        {\floatparameter\c!innermargin}{\floatparameter\c!outermargin}}%
   \alignedline{\floatparameter\c!location}\v!middle}

The reason why the caption disappears is that you put it
in \everyrightofalignedline and the content is replaced with
the rightmargin skip in the \shiftalignedline command.

Thank you Wolfgang, I'll try this as soon as I have access to my ConTeXt.

Your solution doesn't seems to work, I still don't see a caption 
anywhere when using location=rightmargin. When I inserted your fix I 
stumbled upon the fact that there is \def\locatebcaptionbox below 
\def\locatefloatbox. You provided a fix for \locatefloatbox, but 
shouldn't it be for \locatecaptionbox? I have no clues about the 
internals of ConTeXt, but I tried the following:

\def\locatecaptionbox
    {\alignstrutmode\zerocount
 
\doifnotcommon{\floatcaptionparameter\c!location}{\v!outermargin,\v!innermargin,\v!leftmargin,\v!rightmargin}
       {\shiftalignedline
          {\floatcaptionparameter\c!leftmargin 
}{\floatcaptionparameter\c!rightmargin}%
 
{\floatcaptionparameter\c!innermargin}{\floatcaptionparameter\c!outermargin}}%
     \alignedline{\floatparameter\c!location}\v!middle}

Note that I just translated your fix to \locatecaptionbox. At least it 
didn't throw an error!

My attempt at understanding that explanation: The caption is placed to 
the right of aligned line (because it is supposed to got into the 
margin?), and for all things that are placed that way, 
\everyrightofalignedline is called. And that macro replaces the caption 
with a skip, but should instead skip across the margin skip and then 
place the caption?

No, my fix was correct but it’s not a final solution because it disables
the “leftmargin” and “rightmargin” keys when you place the caption in the margin.

In that case I don't understand how I can place a caption in the margin. 
Should the MWE I included in my first post work now, or not?

Hans included the patch in the core, update your installation in this will work:

\setuplayout
  [width=11cm,
   rightmargin=6cm]

\setupcaption
  [figure]
  [width=\rightmarginwidth,
   location={rightmargin,high}]

\starttext
\placefigure{\input ward }{\externalfigure[cow]}
\stoptext

You can control the vertical position of the caption with the three values “high”, “low” and “middle” for the location key.

Thank you very much!

The importance of explicitly setting the caption width was not obvious 
to me.
