How to join multiple PDF pages to a single Page
there are several ways to perform this task, one easier, one harder
The EASIER: A MULTIVALENT.JAR WAY
Multivalent.jar is a stunning piece of free software able to perform many useful tasks on pdf
you can download from one of these links (the 2009 multivalent.jar build available on sourceforge has no more pdf tools inside)
https://rg.to/file/c6bd7f31bf8885bcaa69b50ffab7e355
you need to know the width and height of your pdf (in Linux you can use pdfinfo)
- assuming your multipage pdf is in ISO A4 size (21x29.7cm), type:
java -cp path..to/Multivalent.jar tool.pdf.Impose -dim 4x1 -paper 84x29.7cm input.pdf
this is the resulting page, composed by the 4 sequential pages stitched side by side together:
- resulting pdf file http://ge.tt/98Kv4ce/v/0
explication:
-dim 4x1 means number of columns for rows
-paper 84x29.7cm means paper size of your final imposed document containing the 4 pages joined side by side. obviously, since in your final pdf file, you will have 4 columns and only one row, you need to multiply by 4 the document witdh (21 cm)
multivalent can accept, as unity input, also inches (-paper 33.4x11.68in) or postscript points (-paper 2380x841pt)
THE HARDER: A LATEX WAY:
4_pdf_pages_appended_side_by_side
some years ago, Peter Flynn, in comp.text.pdf suggested, for a similar task, a way to appending pdf pages side by side with the only help of LateX. If you are a LaTeXian, you can act as follows:
since you need to append side by side the four pages of your single multipage pdf, you will write a latex preamble, creating a new document like this:
assuming your pdf document has name input.pdf and its size is ISO A4, and you have this multipage pdf in your working folder, you will have
\documentclass[a4paper]{article}
\usepackage[margin=0mm,nohead,nofoot]{geometry}
\usepackage{pdfpages}
\pagestyle{empty}
\parindent0pt
\begin{document}
\includepdfmerge[nup=1x4,landscape]{input.pdf,1,input.pdf,2,input.pdf,3,input.pdf,4}
\end{document}
If you use a Unix-like operating system, there is pdfjam, which combines the Latex backend with an easy command:
pdfjam --nup 1x4,landscape input.pdf
EDIT: recently I had issues with pdfjam with that exact command. I had it working with:
cat input.pdf | pdfjam -nup 1x4 -landscape –outfile out.pdf
