Guix

MuPDF is a C library that implements a PDF and XPS parsing and rendering engine. It is used primarily to render pages into bitmaps, but also provides support for other operations such as searching and listing the table of contents and hyperlinks.

The library ships with a rudimentary X11 viewer, and a set of command line tools for batch rendering pdfdraw, rewriting files pdfclean, and examining the file structure pdfshow.
