Ok, some days later I'm still not where I'd like to be (and my deadline is overdue). Let’s resume: A running text is to be interrupted by spans of 3 pages. Postponing (\startpostponing) works well for that, but I need to switch off page numbering on two of that 3 pages - as far as I tried, \setuppagenumbering as well as \setuppagenumber doesn’t work within postponed sections. Further, these pages contain full-page pictures, i.e. I need them bleeding off the paper. Normally, \setlayer works well for that, but I couldn’t get layers working within postponed sections. Since I need these interruptions several times in a very similar way, I \def’ed that postponing stuff as a macro, but get errors that point to expanding problems (I never get those). I’d appreciate some pointers in which direction I should think/ investigate further. E.g. - are there alternatives to postponing? perhaps multi-page floats (but at defined pages)? - is there a possibility for bleeding full-page pictures without layers? - can it work at all to change page numbering within a postponed page span?

\startmakeup[page] page a \stopmakeup

Good hint. I setup: \definemakeup[rightpage][page=right] \definemakeup[leftpage][page=left] and get empty right/left pages from within my macro. Can I control if the content after a markup starts on a right or left page? Further, if I try to use postponing in a macro, I get errors: --- *** --- Runaway argument? \dorecur\section{K\ETC. \stoppostponing !

* I need full-page pictures on defined pages in the middle of a chapter.

* I don’t care if I must define "on page x" or "on the next right page after the current paragraph".

- The only way for full-page pictures (i.e. bleeding over the page) that I know of is layers. - The only way to interrupt a story with full-page content that I know of is postponing. (makeups were a dead end so far - maybe they can help to get to a right page withput using \page[right])

While each works for itself, I can’t get layers working within postponing.

And when that works, I need to wrap it in a macro, since I alway need to define and postpone three sequential pages.

Without postponing, this works:

--- *** --- \setuppagenumbering[alternative=doublesided] \definelayer[bg][x=0mm,y=-3mm,width=\dimexpr(\paperwidth+3mm),height=\dimexpr(\paperheight+6mm)] %\definemakeup[rightpage][page=right]

       \resetlayer[bg]        \setlayer[bg]{\externalfigure[#1][height=\dimexpr(\paperheight+6mm)]}        \setupbackgrounds[page][background=bg]        \strut

       %\stopmakeup

       % empty back of the first picture, since it’s printed on transparent paper        %\startmakeup[rightpage] % error!        \page[right]

       \resetlayer[bg]

Can you show me a way to use layers within postponing, please? A first step --- still quite similar to your macro. Hope it helps just for now.

What did you change? Who knows... I'm always try to use the latest beta, and sometime I make some confusion.

I also overlooked that there is no image, i.e. layer is not visible. True: The next one I've a problem with the pagenumber on header, but I can use \setupbackgrounds[page][background={foreground,bg}]

Great, I didn’t know \offset (or I forgot)! This way it’s much easier! Thank you very much! Of course, the \offset stuff works in a macro, but not postponing. But I can live with three lines of code per insertion. Greetlings, Hraban
