[gentoo-user] Joining PDFs and/or jpegs together. Help, please!

[Alan Mackenzie]

Hello, Gentoo,

I'm back again after something kicked me off the mailing list some while
ago.

I have a problem, in that I need to join several PDFs or jpegs output
from xsane (the scanner program) into a single document.

I don't know which program can do this for me.  Would somebody please
recommend one (or even two) to me, please.

Thanks!

For joining PDFs I use "pdftk" from "app-text/pdftk".

Sincerely,

I've got something called pdfarranger in my world file. Iirc it's a 
simple python app that can combine pdfs, delete pages, etc etc. You'll 
have to look it up and see whether it suits what you want, I think I've 
used it once and just left it there in case I need it again.

Cheers,
Wol

I used this just the other day to put two page pdf together.  I'm not
sure about images tho.

convert front.png back.png duplex.pdf

front is page one, back is page two and duplex is output file name.  I'd
guess one could do more than two pages to tho.  I've never done it. 

You should have a few options for this given other replies.

I use pdfjam (which is in app-text/texlive-core) for this sort of
thing, and it's pretty fantastic.  It's pretty dependency heavy if you
dont already use texlive though, as it's using texlive's pdfpages as
its backend.  So if you're a latex user I'd go that way, if not use
one of the other recommended tools

I've had good luck with gscan2pdf before.  It's a GUI that handles
scanning and joining all in one.

It requires dev-lang/perl[ithreads] though which if you don't have
ithreads enabled already is a full Perl rebuild with perl-cleaner,
annoyingly.

Cheers,
Bryan

If you use "convert"[1], you should use the parameter "-density" with a 
decent value. "150" was always good enough for me:

     $ convert -density 150 *.png some_document.pdf

Also, XSane is capable of creating multipages, while scanning[2].

written in HTML:

     $ xdg-open /usr/share/doc/imagemagick-*/html/index.html

Spanish website. :)
