pdfstitch

pdfstitch does a similar job to pdfnup but focuses on the following features:

Crop pages to a certain size
Adjust the crop position per page

It has been created to print sewing patterns distributed as A4 or Letter PDFs on a large format printer thus saving oneself the hassle of cutting and gluing individual pages.

Dependencies

pdfstitch makes use of the following Perl modules:

File::Basename (part of perl base)
File::LibMagic
Getopt::Long (part of perl base)
PDF::API2
YAML

On Debian, you can install them with:

# apt install libfile-libmagic-perl libpdf-api2-perl libyaml-perl

On FreeBSD, you can install them with:

# pkg install p5-File-LibMagic p5-PDF-API2 p5-YAML

Usage

Run pdfstitch on your input PDF:

./pdfstitch [--genmeta] [--defaultcrop=0.9] foobar.pdf

This will generate a YAML file called foobar.pdf.stitch. Edit this file according to the desired output. This is also the default action if called with a PDF. Per default 10% (factor 0.9) is applied as crop factor. You can adjust this value with the --defaultcrop parameter.
Optional: Generate a preview and/or cropped PDF:

./pdfstitch --preview foobar.pdf.stitch

This will generate a new PDF called foobar-preview.pdf. It contains only the pages you select in the YAML file with each page being overlayed with a transparent box showing the area the page will be cropped to.

./pdfstitch --crop foobar.pdf.stitch

This will generate a new PDF called foobar-cropped.pdf. It contains only the pages you select in the YAML file with each page being cropped accordingly.
Generate the final stitched PDF:

./pdfstitch --stitch foobar.pdf.stitch

This will generate a single-page PDF called foobar-stitched.pdf with all selected pages being stitched together as specified in the YAML file. This is also the default action if called with just a YAML file.

Notes

The output file name is based on the .stitch file name.
All output files are placed in the current working directory.
