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 Wolfgang
