This is a README for the font compression reference code. There are several compression related modules in this repository. brotli/ contains reference code for the Brotli byte-level compression algorithm. Note that it is licensed under an Apache 2 license. src/ contains the C++ code for compressing and decompressing fonts. # Build & Run This document documents how to run the compression reference code. At this writing, the code, while it is intended to produce a bytestream that can be reconstructed into a working font, the reference decompression code is not done, and the exact format of that bytestream is subject to change. ## Build On a standard Unix-style environment: ``` git clone https://github.com/google/woff2.git cd woff2 git submodule init git submodule update make clean all ``` ## Run ``` woff2_compress myfont.ttf woff2_decompress myfont.woff2 ``` # References http://www.w3.org/TR/WOFF2/ http://www.w3.org/Submission/MTX/ Also please refer to documents (currently Google Docs): WOFF Ultra Condensed file format: proposals and discussion of wire format issues (PDF is in docs/ directory) WIFF Ultra Condensed: more discussion of results and compression techniques. This tool was used to prepare the data in that document.
