MuPDF 1.7


MuPDF is a lightweight PDF, XPS, EPUB and CBZ viewer and parser/rendering library. The renderer in MuPDF is tailored for high quality anti-aliased graphics. It renders text with metrics and spacing accurate to within fractions of a pixel for the highest fidelity in reproducing the look of a printed page on screen.

MuPDF is also small, fast, and yet complete. MuPDF support PDF 1.7 with transparency, encryption, hyperlinks, annotations, search and many other bells and whistles. MuPDF can also read XPS documents (OpenXPS / ECMA-388), EPUB and CBZ (Comic Book archive) files.

MuPDF is written to be both modular and portable; the example applications are merely thin layers on top of the functionality offered by the library, so custom viewers can be easily built for a wide range of platforms. Example viewer applications are supplied for Windows, Linux, MacOS, iOS and Android.

MuPDF is deliberately designed to be threading library agnostic, while still supporting multi-threaded operation. In the absence of a thread library it will run single-threaded, but by adding one significant benefits in rendering speed on multi-core platforms can be obtained.

Interactive features such as form filling, javascript and transitions are in development and partially supported by the Android application.
