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

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.

The zathura-pdf-poppler plugin adds PDF support to zathura by using the poppler rendering engine.

Pdfgrep searches in pdf files for strings matching a regular expression. Support some GNU grep options as file name output, page number output, optional case insensitivity, count occurrences, color highlights and search in multiple files.

PyPDF2 is a pure Python PDF library capable of:

1. extracting document information (title, author, …)

2. splitting documents page by page

3. merging documents page by page

4. cropping pages

5. merging multiple pages into a single page

6. encrypting and decrypting PDF files

By being pure Python, it should run on any Python platform without any dependencies on external libraries. It can also work entirely on StringIO objects rather than file streams, allowing for PDF manipulation in memory. It is therefore a useful tool for websites that manage or manipulate PDFs.

Paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file through the Pango Cairo back end.

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

fbida contains a few applications for viewing and editing images on the framebuffer.

diffpdf lets you compare PDF files, offering three comparison modes: words, characters, and appearance.

pydyf is a low-level PDF generator written in Python and based on PDF specification 1.7.

The cpdf package provides a command-line tool and an OCaml library designed for manipulating PDF documents. Key Features include:

• Splitting and merging PDF files (including bookmark preservation and splitting on bookmarks).

• Encryption and decryption (supports AES 128 and AES 256).

• Page manipulation: scaling, rotation, cropping, and flipping; fitting pages to a specific size.

• Bookmark management: copying, removing, and adding bookmarks.

• Watermarking: stamping logos, page numbers, and multi-line text with transparency support.

• Text and font handling: embedding TrueType fonts, supporting Unicode UTF-8 input and output, and converting text to PDF.

• Presentation features: creating PDF-based presentations and arranging multiple pages on a single page.

• Annotation management: listing, copying, setting, and removing annotations.

• Metadata management: reading and setting document information and metadata.

• Attachment handling: adding and removing file attachments to documents or pages.

• Advanced features: thickening hairlines, blackening text, reconstructing malformed files, detecting missing fonts and low-resolution images, exporting/importing in JSON format, and building table of contents.

• Drawing: Adding graphics and text directly onto PDF files.

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.

PDFCrack is a simple tool for recovering passwords from PDF documents that use the standard security handler.

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

This package provides a tool for doing everyday things with PDF documents. It can:

• Merge PDF documents or collate PDF page scans

• Split PDF pages into a new document

• Rotate PDF documents or pages

• Decrypt input as necessary (password required)

• Encrypt output as desired

• Fill PDF forms with X/FDF data and/or flatten forms

• Generate FDF data stencils from PDF forms

• Apply a background watermark or a foreground stamp

• Report PDF metrics, bookmarks and metadata

• Add/Update PDF bookmarks or metadata

• Attach files to PDF pages or the PDF document

• Unpack PDF attachments

• Burst a PDF document into single pages

• Uncompress and re-compress page streams

• Repair corrupted PDF (where possible)

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.

unpaper is a post-processing tool for scanned sheets of paper, especially for book pages that have been scanned from previously created photocopies.

Its main purpose is to make scanned book pages better readable on screen after conversion to PDF. Additionally, unpaper might be useful to enhance the quality of scanned pages before performing OCR.

Sioyek is a PDF viewer with a focus on textbooks and research papers.

GNU Pem is a simple tool for tracking personal income and expenses. It operates from the command line and it stores its data in a basic text format in your home directory. It can easily print reports of your spending on different expenses via a basic search feature.

This module provides the most commonly used testing functions, along with automatically turning on strict and warning and gives a bit more fine-grained control over test suites.

Test::Fatal is an alternative to the popular Test::Exception. It does much less, but should allow greater flexibility in testing exception-throwing code with about the same amount of typing.

Loading this plugin causes your tests to fail if there any warnings while they run. Each warning generates a new failing test and the warning content is outputted via diag.
