libpopplerqt5qt6

libpopplerqt5qt6 is a runtime library in the Poppler project that provides Qt bindings for Poppler's PDF rendering and text extraction facilities for applications built with either Qt5 or Qt6. The library offers a Qt-oriented API that mirrors the Poppler core classes, enabling developers to render PDF pages to QImage, extract text, access document metadata, outlines, and annotations, and draw content with QPainter.

The library is designed to ease packaging and distribution by providing both Qt5 and Qt6 bindings in a single package. It exposes interfaces compatible with the corresponding Qt version used by the application, allowing code written for Qt5 to use the library alongside code written for Qt6, without requiring separate runtime libraries for each binding set.

Usage typically involves including the appropriate Qt binding header (for example, the Qt5 or Qt6 variants) and linking against libpopplerqt5qt6. The API surface is designed to be familiar to Poppler users: Poppler::Document for loading PDFs, Poppler::Page for page-level operations, and Poppler::PageRenderer (or equivalent) to render pages to QImages or paint onto QPaintDevice.

Dependencies include the Poppler core library and the Qt framework (Qt5 or Qt6). The library is released under the same licensing terms as Poppler (GPL or LGPL, with common exemptions for Qt bindings in some configurations).

Developers should consult the specific version’s documentation for feature parity and deprecation notes, as some features may be available in one Qt version but not the other. See also Poppler, Qt, and the separate libpoppler-qt5 and libpoppler-qt6 bindings.
