a small .pdf management tool with a command-line UI - 2mol

How could I merge / join PDF on linux cmdline terminal

preprocess (unpaper) and ocr (tesseract) pdf files and 'sandwich' the text behind the image -> output is a selectable pdf

seems perfect for pdf pipeline

PDF viewer for linux:

• few dependencies
• relatively small
• zathura-like hjkl movement
• rest of movement may be bindable like zathura?
• can open annotation viewer/editor with a
• can invert color with I, tint color with C
• runs on opengl (the newer mupdf-gl version)

• shows highlights and annotations
• can create note-based annotations (not highlights though?)
• can be customized to vim-like keys
• minimal interface and distraction

Python PDF Parser -- fork with Python 2+3 support using six - pdfminer

Extracts and formats text annotations from a PDF file - 0xabu

Python script to do PDF OCR conversion using Tesseract - virantha

This is also what paperless uses for its OCR process

A small utility making use of the pypdf library to provide a (somewhat) lighter alternative to pdftk - hellerbarde

allows differentiating between physical and logical pages, might be useful

I want a python function that takes a pdf and returns a list of the text of the note annotations in the document. I have looked at python-poppler

I want to edit the metadata of a scanned PDF to assign custom page numbers to different pages. For example, what are now pages 1-3 I might want to call i, ii and iii, and what are pages 4-10, I wan...

PDF 'Meta-Data' and Formatting Tools:

• pdftk - allows changing page order, extracting pages, combining pages (or image files) to one pdf
• jPdf - similar features to pdftk; allows adding bookmars, renumbering pages, watermarks, attachments, encryptiong, signing, etc
• ABBYY FineReader (win) - OCR and image editing
• irfanview(win)/xnview(unix) - allows batch editing the extracted image files

Annotation:

• Okular - the KDE pdf viewer, annotation works well and fast, dark mode/light mode, -needs many KDE dependencies installed
• MasterPDF Editor - small, fast, many annotation features; -previous Okular annotations don't seem to show up? (don't know if incompatible)

Search:

• rga - ripgrep through the fulltext of all manner of files (zip, tar, epub,..) including pdf
• fast-p - extract and search through pdf fulltext with fzf

MasterPDF Editor seems awesome, and can be customized almost to vim-like keybinds. It's free in the aur (watermark removed version)

From previous experience, I found that I was making too many knowledge items while reading, which made it hard to identify the really important ones. So now, I read through the entire document (article PDF or chapter of a monograph) and mark down possible knowledge items (yellow highlight in citavi PDFs, pencil or 3M flags in printed materials). Then when I've finished, I write a summary knowledge item in 2 paragraphs—the first outlines the argument, the second (in italics) gives my evaluation and thoughts about possible uses. (I don't use the evaluation field in the contents tab as I want to be able to see this quickly in the knowledge view.) Now I'll go back through the marks I've made and work out which ones I want to input as knowledge items. As part of the input, I will assign to as specific category as possible. Every few days, I will have a look through my outline to see where the holes are (not a lot of knowledge items), and to see if anything in the NOT SURE YET category sparks any new thoughts on organization.
