I noticed that the text in the margin is not actually quite aligned with the top of the figure; I think the text starts at the baseline of the line that would be there if the figure was not, if you know what I am getting at. That is at 12pt font size the text is about 12pt below the top of the figure. I tried to fix that with some negative \vskip, but that does not seem to work. Could you suggest an alternative please and maybe even explain why the code below does not compile

I experimented swapping the \rlap for \llap, but then I still have to negatively \hskip the entire text width to the left. Even if I got that to work, I will have to wrap everything in an if-statement and have one branch for left and one for right pages. Right? How do I find out whether I am on a left or a right page? In other words, how would the if-statement look like.


\setuppagenumbering[alternative=doublesided]

\starttext

     \definelayer
       [extrafiguretextlayer:l]
       [width=\overlaywidth,
        height=\overlayheight,
        corner={right,top},
        location={right,bottom},
        x=-1cm]

       [extrafiguretextlayer:r]
       [width=\overlaywidth,
        height=\overlayheight,
        corner={left,top},
        location={left,bottom},
        x=-1cm]

     \startsetups extrafiguretext
         \signalouterrealign

           [extrafiguretextlayer:\rightorleftpageaction rl]

           [width=\marginwidth,

            foregroundstyle=\tx]
           {\floatuserdataparameter{text}}
         \flushlayer

     \stopsetups

     \defineoverlay
       [extrafiguretext]
       [\setups{extrafiguretext}]

     \setupfloat
       [figure]
       [background={foreground,extrafiguretext}]

     \dorecurse {20} {

         \startplacefigure[title=Dummy figure][text={margin dummy text #1}]
             \externalfigure[dummy][width=.8\textwidth]
         \stopplacefigure

     }

\stoptext
