hwdata contains various hardware identification and configuration data, such as the pci.ids and usb.ids databases. Each database is contained in a specific package output, such as the pci output for pci.ids, the usb output for usb.ids, etc.

The PCI Utilities are a collection of programs for inspecting and manipulating configuration of PCI devices, all based on a common portable library libpci which offers access to the PCI configuration space on a variety of operating systems. This includes the lspci and setpci commands.

The PCRE library is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5. PCRE has its own native API, as well as a set of wrapper functions that correspond to the POSIX regular expression API.

Poppler is a PDF rendering library based on the xpdf-3.0 code base. Poppler gives access to the following binary programs:

• pdfattach

• pdfdetach

• pdffonts

• pdfimages

• pdfinfo

• pdfseparate

• pdfsig

• pdftocairo

• pdftohtml

• pdftoppm

• pdftops

• pdftotext

• pdfunite

pdfposter can be used to create a large poster by building it from multiple pages and/or printing it on large media. It expects as input a PDF file, normally printing on a single page. The output is again a PDF file, maybe containing multiple pages together building the poster. The input page will be scaled to obtain the desired size.

This is much like poster does for Postscript files, but working with PDF. Since sometimes poster does not like your files converted from PDF. Indeed pdfposter was inspired by poster.

PoDoFo is a C++ library and set of command-line tools to work with the PDF file format. It can parse PDF files and load them into memory, and makes it easy to modify them and write the changes to disk. It is primarily useful for applications that wish to do lower level manipulation of PDF, such as extracting content or merging files.

Xournal is an application for notetaking, sketching, keeping a journal using a stylus.

This package provides a PDF library capable of splitting, merging, cropping, and transforming PDF files.

A4PDF is a low-level library for generating PDF files. It does not have a document model and instead uses PDF primitives directly. It uses LittleCMS for color management but otherwise does not convert data in any way.

libHaru is a library for generating PDF files. libHaru does not support reading and editing of existing PDF files.

This package provides Python bindings for the Qt5 interface of the Poppler PDF rendering library.

Impressive is a tool to display PDF files that provides visual effects such as smooth alpha-blended slide transitions. It provides additional tools such as zooming, highlighting an area of the screen, and a tool to navigate the PDF pages.

This package provides optional encoding files for Poppler. When present, Poppler is able to correctly render CJK and Cyrillic text.

img2pdf converts images to PDF via direct JPEG inclusion. That conversion is lossless: the image embedded in the PDF has the exact same color information for every pixel as the input.

MuPDF is a C library that implements a PDF and XPS parsing and rendering engine. It is used primarily to render pages into bitmaps, but also provides support for other operations such as searching and listing the table of contents and hyperlinks.

The library ships with a rudimentary X11 viewer, and a set of command line tools for batch rendering pdfdraw, rewriting files pdfclean, and examining the file structure pdfshow.

flyer-composer can be used to prepare one- or two-sided flyers for printing on one sheet of paper.

Imagine you have designed a flyer in A6 format and want to print it using your A4 printer. Of course, you want to print four flyers on each sheet. This is where Flyer Composer steps in, creating a PDF which holds your flyer four times. If you have a second page, Flyer Composer can arrange it the same way - even if the second page is in a separate PDF file.

This package contains both the command line tool and the gui too.

Stapler is a pure Python alternative to PDFtk, a tool for manipulating PDF documents from the command line. It supports

• cherry-picking pages and concatenating them into a new file

• splitting a PDF document into single pages each in its own file

• merging PDF documents with their pages interleaved

• displaying metadata in a PDF document

• displaying the mapping between logical and physical page numbers

PyMuPDF is a set of Python bindings for MuPDF, which is a viewer, renderer, and toolkit for files in PDF, XPS, OpenXPS, CBZP, EPUB and FB2 (e-books) format.

pdf.tocgen is a set of command-line tools for automatically extracting and generating the table of contents of a PDF file. It uses the embedded font attributes and position of headings to deduce the basic outline of a PDF file.

It works best for PDF files produced from a TeX document, but it's designed to work with any software-generated PDF files (i.e. you shouldn't expect it to work with scanned PDFs). Some examples include troff/groff, Adobe InDesign, LibreOffice Writer, and probably more.
