How to Use Xournal

The way to use annotation apps is to use them as a way to increase the visibility of corrections from your writing. If you are writing on paper or a blog, you can use an annotation application to write notes in the margins of the document. This will help you remember to follow your writing plan and remember what you need to do next.

You can also use annotation apps as a way to keep track of important information. Annotation apps have different tools that can help you keep track of what you need to do. You can write a reminder for yourself and then mark it with a tick. This can be a great way to keep yourself motivated. You can also use annotation apps to create checklists. This is great for organizing your to-do list.

Correcting PDF Tasks

Run Xournal++, open the PDF file by clicking the “Open file” icon or via the File >> Open menu, find the PDF file to be corrected and let Xournal++ open the pdf. Then it’s up to you to give strokes, comments, lines, or colors that are used to correct the pdf are available via the toolbar below the menu. Please see pictures:

Conclusion

This Xournal++ application is excellent for handwriting, for in my case I can insert pictures and pdfs and then give notes for students to study. This application has many useful tools, intuitive, clear. You can also annotate PDF files with Xournal++ the only problem is that to have pdf editing facility you have to understand and have LaTeX installed (this can be ignored).

This is the best note annotation software for PDF on Linux I’ve ever used! This app is very light and works well. I’ve been using Xournal++ for several years and I couldn’t find any flaws in it: it has many powerful features and is not a waste of resources. I mainly use it for taking notes during lectures and filling out forms and signing PDF files but Xinput’s functionality makes it a good tool for basic sketching too. Last but not least its compatibility with Linux and Windows. Seriously I couldn’t ask for anything better it’s a cool app thanks Xournal++ team!
