Xournalpp is a digital note-taking and annotation application designed for capturing natural handwriting and sketching. It functions as a vector graphics editor that treats individual strokes, shapes, and text as discrete, editable objects, allowing users to refine and manipulate their work after it has been placed on the canvas.
The application provides a specialized environment for overlaying handwritten notes and drawings onto existing PDF documents. By utilizing pressure-sensitive stylus input, it simulates a natural writing experience, while its layered canvas composition enables users to manage complex annotations without altering the underlying source file.
The software supports a range of document markup and illustration tasks, including the ability to save and retrieve project states through structured XML-based serialization. It is designed to handle input through an event-driven system that ensures responsive rendering of strokes across a variety of academic and creative workflows.
