I would like to use texexec to post-process a large pdf file, so
as to
prepare it for double sided printing. The existing file has a large
left hand "margin" on each page, so as to allow binding.
I would like to change this so that odd (right) pages have a large
left margin, and even (left) pages a large right margin.
\setuppagenumbering[alternative=doublesided]
\setuplayout[horoffset=1cm]
\setuplayout[page]
\starttext
\copypages[document]
\stoptext
Thanks, that's great!
Is there an easy way to compensate for the original offset? The
original pdf has a large left margin and a small right one.
Replace 'page' with the name of your document.
\setuplayout[page]
\starttext
\getfiguredimensions[pages]
\dorecurse\noffigurepages
  {\hbox to \textwidth
     {\ifodd\recurselevel
        \hskip-2cm\externalfigure[pages][page=\recurselevel]\hss
      \else
        \hskip-1cm\externalfigure[pages][page=\recurselevel]\hss
      \fi}}
\stoptext
Thanks Wolfgang, I got that to work perfectly. I had to fiddle around with
it, I put the result on the Wiki

http://wiki.contextgarden.net/Including_pages_from_PDF_document


(Please move/amend as appropriate)


% replace "Manual" with the name of your original pdf
\define\MySingleSidedDocument{Manual}

% can adjust topspace to move page etc
\setuplayout[\MySingleSidedDocument,topspace=1cm,header=0cm,backspace=0cm]
% suppress page numbering
\setuppagenumbering[location=]

\starttext

\getfiguredimensions[\MySingleSidedDocument]

\dorecurse\noffigurepages
  {\hbox to \textwidth
     {\ifodd\recurselevel
%adjust number to set odd page horizontal position
        \hskip-0.1cm\externalfigure[\MySingleSidedDocument][page=\recurselevel]\hss
      \else
%adjust number to set even page horizontal position
        \hskip-1.8cm\externalfigure[\MySingleSidedDocument][page=\recurselevel]\hss
      \fi}}
\stoptext
