I am producing the cover of a journal in LaTeX. I have separate files for the frontcover, backcover and spine. I would like to combine these into a single seamless PDF that has the height of an A5 sheet of paper but width (2*A5width+1cm) (the spine is 1cm wide). I have tried using pdfpages, but it adds space around the spine as though it was an A5 sheet:
\documentclass{article}
\usepackage{pdfpages}
\usepackage[a5paper,margin=0.7in]{geometry}
%\usepackage{}% A local style file for this specific journal; I don't think the other packages are relevant.
\geometry{paperwidth={2\paperwidth+1cm}}
\begin{document}
\includepdfmerge[nup=3x1]{backcover,spine,frontcover}
\end{document}



delta=-0.5in 0inas in\includepdfmerge[nup=3x1,delta=-0.5in 0in]{pgfmanual,pgfmanual,pullquote}Use appropriate length so as to remove the space. Will this work? – Nov 19 '13 at 00:20
