Hi all,
I am siting with a project of making a “dwarsligger”, you know these books,
printed on bible-thin-printing paper, which are about 12 x 8 cm. One opens
them while holding them ‘landscape’ with the spine on the top…
Now there is of course a little struggle with the page numbering. The reading
page consists out of the even page together with the following uneven page. It
is easy to print on the uneven page a page number, however this will result in
uneven page numbers only throughout the book.
My question is, whether there is an algorithm to print page numbers as follows:
1 2 3 4 5 6 7 8 9 (this is the ordinary numbering)
1 2 3 4 5 (this is the requested numbering)
Does someone have an idea how to solve this?
Variant 1:
\setuppapersize[A5,landscape]
\setuppagenumbering[location=none]
\startsetups [pagenumber]
\doifoddpageelse
{\cldcontext{"\letterpercent d",(\pagenumber+1)/2}}
{}
\stopsetups
\setupheadertexts [\directsetup{pagenumber}]
\starttext
\dorecurse{10}{\samplefile{knuth}}
\stoptext
Variant 2:
\defineexpandable[1]\DwarsliggerNumber
{\cldcontext{"\letterpercent d",(#1+1)/2}}
\defineconversion [dwarsligger] [\DwarsliggerNumber]
\setuppapersize[A5,landscape]
\setupuserpagenumber[numberconversion=dwarsligger]
\setuppagenumbering[location=none]
\setupheadertexts [\doifoddpageelse{\prefixedpagenumber}{}]
\starttext
\dorecurse{10}{\samplefile{knuth}}
\stoptext

In many times, it's better to start from zero, so it could be that you have to translate your input sequence by adding -1 and the output sequence by adding +1 . > -- luigi ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___
