HexaPDF VS xournalpp

An example for a very simple setup is the cmdparse gem documentation. It only has a few additional documentation files that accompany the main API documentation. The other end of the spectrum is the documentation for HexaPDF which encompasses many additional documentation files besides the API documentation and deeply integrates the API docs into the whole documentation website.

HexaPDF is a Ruby OSS library with a commercial version available and profitable.

So I'm collecting feature ideas for that table implementation at https://github.com/gettalong/hexapdf/discussions/231.

Hi there! I'm the author of HexaPDF.

git clone https://github.com/gettalong/hexapdf.git

You can use this HexaPDF script to do this:

I have just released my new gem hexapdf-extras which provides additional functionality on top of the HexaPDF library.

You can use HexaPDF together with a small script to do this (see the third line on how to use the script):

TrueType subsetting mainly consists of generating the necessary glyph and various index tables, and copying over all the other necessary tables which don't need to be adjusted. See https://github.com/gettalong/hexapdf/blob/master/lib/hexapdf/font/true_type/subsetter.rb for what is needed to subset.

I highly recommend Rnote to anyone on Linux that misses the "hodgepodge" notetaking of apps like OneNote. It works like a dream on touchscreens and drawing tablets, with a surprising amount of configuration under the hood.

Also worth noting is Xournal, an older but similar project: https://xournalpp.github.io/

I've been using Xournalpp[1] for many years, highlighting books as I read them, adding in text/hand drawn annotations in whitespaces if necessary. Unlike other PDF readers/annotators, it saves a separate file, so the original PDF is untouched. It can also export the annotated PDF as a new PDF with highlights and annotations.

Obsidian[2] also has PDF support, where you can open a markdown document side by side with the PDF to take notes as you read. I think it also lets you highlight the PDF itself.

Emacs I think has a similar feature, via plugins/org-mode(?) to the Obsidian setup.

And of course your typical PDF reader probably has support for highlighting PDFs too, but I find them clunky and they save by exporting a PDF, which can be a bit heavy-handed IMO compared to just saving the annotations/highlights as a separate file as Xournalpp does.

Currently, I am trying to build a small open source NLP project for which I first find text on a page and then translate it; see the current project state here: https://github.com/PellelNitram/xournalpp_htr. The purpose of this project is to make handwritten text in Xournal++ searchable for all users.

[Xournal++](https://xournalpp.github.io/) is in my option the best handwritten note-taking software out there, because it has all the coolest features (like LaTeX snippets and shapes) and it's open source too, so make sure to check it out!
