multi-page floats

multi-page floats

[Henning Hraban Ramm]

Hi again,
in my current book project there are sets of full-page graphics, where  
there’s first a drawing, to be printed on transparent paper, followed  
by a water colour picture as background, i.e. a series of

right page: foreground graphic
right page: background graphic

The transparent pages are left out in pagination.
Between chapters (i.e. stories), the following macro does what I want:

\def\DoublePic#1{
	\page[right] % foreground picture on transparent paper
	
	\setuppagenumbering[state=stop]\setuppagenumber[state=stop]\par
	\resetlayer[bg]
	\setlayer[bg]{\externalfigure[#1-fore][height=\dimexpr(\paperheight 
+6mm)]}
	\setupbackgrounds[page][background=bg]
	\strut\par % page needs some content
	
	\page[right] % background picture on normal paper
	
	\setuppagenumber[state=start]\par
	\resetlayer[bg]
	\setlayer[bg]{\externalfigure[#1-back][height=\dimexpr(\paperheight 
+6mm)]}
	\setupbackgrounds[page][background=bg]
	\strut\par
	
	\page
	\setuppagenumbering[state=start]
}


Now, the publisher would like to move the picture pages in the middle  
of the stories, i.e. I need them to float "here" without manual page  
breaking.
How can I achieve that?

I’d also appreciate enhancements to my macro above.

(MkIV latest beta on OSX Intel.)

Thank you very much in advance!

Greetlings, Hraban

\startpostponing

might help (you can add [pagenumber] or [+pagenumber] if needed)

Oh, of course, Philipp Gesang recently reminded me.
I would like to use \startpostponing[right], but fixed pages are ok.


This works:

\starttext

\startpostponing[3]
	\section{Tufte}
	\input tufte
	\strut
	
	\page
	\strut
	
	\page
	
	\section{More Tufte}
	\input tufte
	
	\page
\stoppostponing

\dorecurse{30}{
	\section{Knuth \recurselevel}
	\input knuth
}

\stoptext


But if I try to put graphics in layers within the postponing, I get  
empty pages.
Further, if I put that postponing stuff into a macro (see below), I  
get errors about \par ending the buffer. I guess I’d need some  
unexpanding, but where?
Without \def, I get 2 (instead of 3) empty pages, but with page  
numbers. I need to switch off the pagenumbering for the first two  
pages (because it’s a transparent page that doesn’t count); it’s  
probably also a problem fixed-page postponing...

\def\DoublePicAt#1#2{
	\startpostponing[#2]
	\setuppagenumbering[state=stop]\setuppagenumber[state=stop]
	
	\resetlayer[bg]
	\setlayer[bg]{\externalfigure[#1][height=\dimexpr(\paperheight+6mm)]}
	\setupbackgrounds[page][background=bg]
	\strut
	
	\page %[right] doesn’t work
	\strut
	
	\page
	
	\setuppagenumber[state=start]
	
	\resetlayer[bg]
	\setlayer[bg]{\externalfigure[#1-hg][height=\dimexpr(\paperheight 
+6mm)]}
	\setupbackgrounds[page][background=bg]
	\strut
	
	\page
	\setuppagenumbering[state=start]
	\stoppostponing
}

Thanks in advance!

Greetlings, Hraban

Re: multi-page floats

[Henning Hraban Ramm]

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

\startmakeup[page]
     page b

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
! File ended while scanning use of \buff_gobble.

system          > tex > error on line 0 in file : File ended while  
scanning use of \buff_gobble ...

<empty file>

<inserted text>
                 \par
<*> ./postpone
                \stoptext
--- *** ---

I guess I need to unexpand something?

My example:

--- *** ---

\def\TestPostpone#1{
	\startpostponing[#1]
	\strut
	\page
	\stoppostponing
}

\starttext

\TestPostpone{3}

\dorecurse{30}{
	\section{Knuth \recurselevel}
	\input knuth
}

\stoptext

Re: multi-page floats

[Henning Hraban Ramm]

Sorry for coming back again and again, but I’m still stuck, and my  
deadline is overdue.

* 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]

\def\DoublePic#1{
	%\startmakeup[rightpage] % error!
	\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]
	\setlayer[bg]{\externalfigure[#1-hg][height=\dimexpr(\paperheight 
+6mm)]}
	\setupbackgrounds[page][background=bg]
	\strut
	
	%\stopmakeup
	\page
}

\starttext

\input tufte

\DoublePic{koe}

\input knuth

\stoptext

--- *** ---

This doesn’t:

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

\def\DoublePicAt#1#2{
	\startpostponing[#2]
	\page[right] % tried also makeups...
	
	\resetlayer[bg]
	\setlayer[bg]{\externalfigure[#1][height=\dimexpr(\paperheight+6mm)]}
	\setupbackgrounds[page][background=bg]
	\strut
	
	\page[right]
	\setuppagenumber[state=start]
	
	\resetlayer[bg]
	\setlayer[bg]{\externalfigure[#1-back][height=\dimexpr(\paperheight 
+6mm)]}
	\setupbackgrounds[page][background=bg]
	\strut
	\page
	\stoppostponing
}

\starttext

\DoublePicAt{hacker}{5}

\dorecurse{30}{
	\section{Knuth \recurselevel}
	\input knuth
}

\stoptext

--- *** ---

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.

Uhm I've tested but maybe I've made a wrong cut and paste.

What did you change?
I also overlooked that there is no image, i.e. layer is not visible.

Thank you for your effort, I’ll test it this weekend, but I resolved  
to Wolfgang’s solution using \offset instead of backgrounds, since  
that’s much easier and enough for my needs.

Thank you! Good hint to de-couple postponing and the rest.

\page[right] doesn’t work with this version, but \page\strut\page does.

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.

Multi-page floats

[Giuseppe Bilotta]

Hello,

this is a "request" on the same line as the "looks like float,
smells like a float, but is not a float" request.

The previous request was about defining objects that didn't really
float, but which would have a caption that would follow the
caption numbering of the same class of floats. Of course it made
sense only for "splittable" "floats" (like tables).

More in general, this request is about "multi-page" floats: floats
that could take more than one page (for example, a very long
table). It should be automatically split (which would require the
system to know where to split and how to split, which text to
replicate on the top or bottom of the split etc), and it would
have a caption on each page where it is present, a caption
containing a continuation message on each non-first page.

Is it already available?

you mean \splitfloat [splitsplaatsblok] in page-flt.tex ?

[split and handles 3a 3b 3c like numbering]
