Linux notes in pdf

Как делать заметки в PDF-файлах в Linux

в Adobe Acrobat Pro вы можете делать такие вещи, как помещать маленькие заметки в PDF-файлы, выделять текст и создавать закладки. Я нашел это очень полезным для обучения. В школе вы учитесь лучше, когда вы кладете свои заметки прямо в учебник. Часть материала теперь поставляется в формате pdf.

однако я переключился на Linux. Я нахожу, что есть несколько программ, которые могут читать PDF-файлы, но они не могут делать все те полезные вещи, которые я только что упомянул.

есть ли linux программы? Я нашел программу, которая конвертирует PDF в формат ps. Если я конвертирую pdf в файл ps, существуют ли программы, которые позволяют делать такие вещи?

Xournal можно аннотировать PDF-файлы (и с правильным текстом, а не просто как довольно прихотливы скриншот).

Я использовал его для заполнения неинтерактивных PDF-форм.

Если вы используете KDE, вы можете попробовать Okular стандартный просмотр документов этой среды рабочего стола. Когда в режиме обзора, он может добавить большое количество бликов и аннотаций к PDF файлам

Я использую pdfescape и редактировать PDF-файлы онлайн. Комментарии сохраняются в исходном формате pdf. http://www.pdfescape.com/

обновление: Master PDF editor, который является бесплатным для linux (некоммерческого использования), также является хорошим вариантом. Я использую его уже почти год, и он подходит для большинства моих потребностей.

Mendeley могу сделать все это, плюс это удивительный программного обеспечения для отслеживания вашего PDF:с (поиск, пометки и т. д.). Также,PDF XChange Viewer это бесплатная программа для windows, которая может сделать это тоже, и хорошо работает под Wine (это даже очень быстро). Я использовал оба для заметок во время инженерных исследований.

5 Best free PDF editors for Ubuntu Linux in 2021

Start editing PDF files on Linux distros like Ubuntu 20.04, 18.04; CentOS, Linux Mint Debian, Manjaro, and more using these free but best Linux PDF editor software.

PDF readers and editors are a popular part of our day-to-day work related to documents, ebooks, presentations, whitePaper, and more because of PDF’s portability and security. However, when it comes to reader application for PDF files, you will generally find a one on Linux desktop systems, easily. However, PDF editors may still need to be installed, which are available only a handful.

Adobe developed the PDF (portable document format) in such a way that it can present the layout in the final document as it is, anywhere, regardless of the OS system or software in which you are going to use it later. Therefore, editing PDF files afterward is not an easy task- apart from the standard note and comment functions. However, Adobe offers a professional PDF editor for Mac and Windows but that also has limited capabilities. This means we can edit all PDF files not thoroughly like we do Word documents.

As PDF is an open format and doesn’t restrict to Adobe only, thus, various third party paid, free and open-source software emerged to handle it. Some of them can edit files to some extent while others are only capable of merging, splitting, extracting, annotating, and compressing PDF files.

Well, if you ask how to edit PDF files in Linux many people suggest using Adobe on Linux using Wine. However, that still is not the best method because heavy documents often crash the software.

Some best PDF editors for Ubuntu & other Linux

1. Master PDF Editor on Ubuntu & CentOS

It is one of the popular PDF editor available for Ubuntu and CentOS Linux systems. Master PDF offers a variety of functions to deal with PDF documents. However, it is available in the personal and commercial versions, thus, the free version which is personal will have some limitations.

The free version of Master PDF editor for Linux offers:

• Edit bookmarks in PDF files
• Provides the ability to create a new PDF document from scanner or existing file(s)
• Comment and annotate PDF documents
• Split and merge PDF documents

Whereas, if you want more such as Edit PDF text and images, PDF Form creation, Add/Edit Document Actions; Add Headers and Footers, Watermarks, Backgrounds; 256 bit AES encryption, and more than one has to go for the Commercial version. Learn how to install Master PDF free version on Ubuntu 20.04.

2. Inkscape

Inkscape is a drawing program and works like Adobe photoshop to deal with PDF files. When importing a PDF document, the user can have the PDF fonts replaced by installed fonts with similar names. Its interface is quite good and lets you easily select text and edit them. Apart from that being a vector graphics program, we can deal with different graphics present in PDF files. However, it is not a multi-page editor program like LibreOffice, thus when you import multiple PDF files it will only select the first one to edit.

You can restrict the export to selected parts of the drawing and convert the texts into paths or lines. Inkscape imported his self-written PDF almost perfectly, only merging the text frames one on top of the other into one large one.

The software is available for Linux, Windows, and macOS.

3. LibreOffice Draw for PDF editing

LibreOffice doesn’t need any introduction, it has been around for a very long time and cannot only deal with Word, Excel, or PowerPoint documents even support PDF file creation and editing. The office suite of LibreOffice comes with a Draw module that can open and edit PDF files, however, don’t expect much from it other than basic PDF editing. In Draw, the PDF files become temporarily like images, and with the help of various tools one can modify, edit, save, create PDF files for free.

If desired, bookmarks, comments and a watermark created from any text can be transferred to the PDF. Therefore, it is not a PDF editor for Linux like the Adobe Acrobat (Windows only), however worth trying.

4. Qoppa PDF Studio editor – Free trail

Qoppa is a paid option to edit files in Windows, Linux, or macOS, however, one can try it for free by downloading the trial version. It comes with a good range of features to compete with Adobe Acrobat.

• Create PDFs
• OCR (Text Recognition)
• Digitally Sign PDFs
• Scan-To-PDF
• Annotate and Markup PDFs
• Fill In & Save PDF Forms
• Secure Documents
• Append / Delete Pages
• Create Watermarks, Headers, Footers
• Supports the new PDF 2.0 standards
• And more…

You can install this PDf editor on Ubuntu or any other Linux by downloading its installation script from the official website and running it using the command sh ./PDFStudio_linux.sh . PDF studio is available in both 32-bit and 64-bit versions.

5. Okular

Although Okular is not a PDF editor like the mentioned above, however instead a reader with basic editing skills, or rather I say annotating with the help of pop-ups & inline notes; freehand line drawing, highlighter, stamp, and other features.

Furthermore, after opening PDF files in Okular, we can copy text and save images from them. Okular is a cross-platform application and available for Windows, Linux, and macOS.

Closing thoughts

Of course, Linux distros deprive of some solid free PDF editors, however, actually, PDF format itself developed to keep the layout and other items as it’s so that people couldn’t change things randomly of any file. Yet, the tools given here are enough to edit PDF files, nevertheless, when it comes to editing PDF of scanned documents, even Adobe Acrobat is not perfect as well.

Use Xournal++ to Take Handwritten Notes or Annotate PDFs on Linux

If you’re on the hunt for a handwritten notes app for Linux, be sure to check out Xournal++.

Xournal++ (which goes by the package name xournalpp ) is a free, open-source and fully featured note taking tool for Windows, macOS and Linux desktops.

The app makes it easy to create new handwritten notes, draw diagrams and doodles, and sketch out thoughts. A variety of different paper types are available, including regular lined, squared/graph, and blank.

As Xournal++ is designed for note-taking and sketching it’s best used with a graphics tablet or stylus, but you can use a regular keyboard and mouse too.

Keen to learn more?

Xournal++ Features

The developers of the app describe it as “…hand note taking software written in C++ with the target of flexibility, functionality and speed.”

If you’re well versed in open-source software you may recognise the basis of this app. A souped-up version of the Xournal note-taking app, Xournal++ is so named because, well, it offers several ‘pluses’ that the original app doesn’t.

But these additions make Xournal++ so good that even the developers of the original Xournal now recommend it to their users!

Xournal++ is based on Xournal, but with a stack of additional features…

What makes Xournal++ particularly interesting to me, as someone who’s championed the Write notes app for Linux in the past, is that Xournal++ supports Wacom tablet pen pressure.

Naturally this requires supported hardware, but it is extra useful for diagrams, sketches and adding emphasis to handwritten notes.

Its feature set is reminiscent of the Microsoft’s (long discontinued) Windows Journal app. No surprise; Windows Journal inspired a swathe of similar software across multiple platforms.

Xournal++ features include:

• Support for Pen pressure, e.g. Wacom Tablet
• Support for annotating PDFs
• Fill shape functionality
• PDF Export (with and without paper style)
• PNG Export (with and without transparent background)
• Layer selection
• Map tools to mouse/stylus buttons
• Sidebar with Page Previews
• Support for image insertion
• Configurable eraser tool
• Customizeable toolbar
• Shape drawing (line, arrow, circle, etc)
• Shape resizing and rotation
• Shape recognition

Rather uniquely the app also supports:

• Audio recording and playback

Audio snippets get saved with the rest of the note, making it easy to revisit and replay clips within the original context.

One feature that Xournal++ does lack is OCR; this app cannot detect or translate written words into digital ones.

Easily Annotate PDFs in Linux

A really compelling feature of both Xournal and Xournal++ is the ability markup and annotate PDF documents on Linux. macOS and Windows users have lots of choice in this area, but Linux? Not so much.

You can also import and annotate PDF documents using Xournal++ — which is very handy!

Xournal++ lets you import and open PDFs inside the app so that you can scrawl text on or draw and doodle over documents directly, no additional app or library is needed.

All of the tools available when note taking are available when marking up a PDF document. You can draw free hand in various colours and thicknesses, apply shapes, arrows and callouts, add text, move things, and more.

When you’re done you can choose to export your annotated PDF as a PDF — PDF export actually works here, too — or save it as a Xournal++ file for future editing.

File Format & Export options

To be truly useful as a note taking app you need to be able to easily export notes in common, compatible formats — and i’m pleased to see Xournal++ does just that.

Notes are saved in the .xopp format by default. This is a compressed XML file. PDFs are not embedded into this file so you will need to keep hold of them if you don’t plan on exporting your changes right away.

The app is also able to read/write to the original Xournal .xoj format too, though (obviously) advanced features like page backgrounds types aren’t supported.

All notes can be exported as regular image files ( .jpg , .png ) with transparency on or off, and PDFs can be exported in the same format with markup in tow.

How to Install Xournal++ on Ubuntu

Xournal++ is free, open-source software available for Windows, macOS and Linux. You’ll find a raft of installers and packages on the project Github page:

Ubuntu users can add the Xournal++ PPA to install Xournal++ on Ubuntu 16.04 LTS, 18.04 LTS and 19.04:

Once installed just launch the app from the application screen.

After opening do take some time to explore the various layouts ( View > Toolbar ) and set up your preferred behaviour ( Edit > Preferences ).

If you plan on using the audio recording feature you’ll need to set both an audio folder and the input/output sources via Edit > Preferences ).

Best PDF Editors for Linux to Edit the PDF Content and Extract Pages to Merge in Other PDF Files

Last updated October 29, 2020 By Ankush Das 152 Comments

Almost all Linux distributions come with a PDF viewer but not necessarily a PDF editor. Don’t worry. There are plenty of PDF editors for Linux that you may install and use.

For the most part, you may be looking to achieve some basic tasks like merging, deleting pages, and similar on a PDF editor. But, you may also have a reason to edit the content in a PDF file.

So, when I talk about how to edit PDF files in Linux, it’s for both the use-cases i.e basic and advanced usage.

In other words, PDF editors can be categorized as follows:

• PDF editors that let you edit the content (annotate, highlight, change text, add/remove images etc)
• PDF editors that let you modify the files by merging files, splitting files, extracting pages from files etc.

In this article, I’m going to list the best PDF editors available for Linux accordingly.

Some applications mentioned here are not open source. They are listed here because they are available on Linux and the article’s focus is on Linux. Such applications are duly marked non-FOSS so that you can make a decision yourself.

Best PDF editors for Linux for editing the content of the PDF files

Just to be clear, I’ve tested this on Pop OS 20.04 but you can easily try them on other Linux distributions as well.

1. LibreOffice Draw

Key Features:

• Edit the text in a file
• Add text/images in the file
• Manipulate the existing content
• Supports creating PDF files
• Cross-platform

LibreOffice draw provides a handy way of editing a PDF file. If your requirements are limited and mostly text editing in a PDF document, Draw will serve your purpose. It may not be a full-fledged PDF editor and comes with some limitations but it’s worth trying out.

In case you’re curious, we also have a detailed article on how to edit PDF files using LibreOffice Draw.

How to install LibreOffice?

LibreOffice is free, open source, and comes bundled with most of the distributions. You will not find it as a separate software — but as a part of the LibreOffice suite.

2. Okular

Key Features:

• Different annotation options as part of its review feature
• Cross-platform

Okular is a popular free and open source document viewer developed by KDE which includes basic PDF editing features.

Once you open a PDF file in Okular, you can copy a part of the text to the clipboard by selecting it, or save it as an image.

You can navigate your way through Tools > Reviews menu to get other options like adding pop-ups notes, inline notes, freehand line drawing, highlighter, stamp and other features.

Okular can pretty much handle your basic PDF editing tasks, however, for advanced editing, it may not be that much useful.

How to install Okular?

Okular is available in the software repository of almost all major Linux distributions. You can install it from your software center.

In either case, you can also build it from source through KDE’s website.

3. Scribus

• Move the existing text of a PDF file to re-position it or delete it

Scribus isn’t exactly a PDF editor — but it offers the necessary features to highlight, add content, and a few more things in a PDF file.
