MuPDFQt

MuPDFQt is a widget and application framework for the MuPDF document viewer, written in C++ and designed to integrate with the Qt framework. It provides a set of tools and components that allow developers to embed MuPDF's rendering capabilities into their own Qt applications. This enables the display and interaction with various document formats, most notably PDF, but also supporting EPUB, XPS, and CBZ among others.

The primary purpose of MuPDFQt is to bridge the gap between the C-based MuPDF library and the C++ Qt ecosystem. It offers a more object-oriented and Qt-friendly interface compared to directly using the MuPDF C API. This includes classes for document handling, page rendering, annotation management, and text selection, all designed to be used within a Qt application's event loop and widget system.

MuPDFQt can be used to build standalone document viewer applications or to add document viewing functionality to existing Qt software. Its features often include smooth zooming, text searching, page navigation, and support for interactive form elements. The project is typically open-source, making it a flexible choice for developers seeking a lightweight and efficient PDF rendering solution within their Qt projects. It aims to provide a balance between performance, features, and ease of integration for cross-platform development.
