Fitz¶
If you wonder where the prefix “fz” and name Fitz come from, MuPDF originally started out as a prototype of a new rendering library architecture for Ghostscript. It was to be a fusion of libart and Ghostscript. History turned out differently, and the project mutated into a standalone PDF renderer now called MuPDF. The “fz” prefix for the graphics library and core modules remains to this day.
