Go wrapper for MuPDF fitz library that can extract pages from PDF, EPUB, MOBI, DOCX, XLSX and PPTX documents as IMG, TXT, HTML or SVG.
extlib
- use external MuPDF librarystatic
- build with static external MuPDF library (used with extlib
)pkgconfig
- enable pkg-config (used with extlib
)musl
- use musl compiled librarynocgo
- experimental purego implementation (can also be used with CGO_ENABLED=0
)The bundled libraries are built without CJK fonts, if you need them you must use the external library.
Calling e.g. Image() or Text() methods concurrently for the same document is not supported.
Purego implementation requires libffi
and libmupdf
shared libraries on runtime.
You must set fitz.FzVersion
in your code or set FZ_VERSION
environment variable to exact version of the shared library.
