README

        
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 the MIT 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.

The build process depends on the g++ compiler.

## Build

On a standard Unix-style environment:

```

git clone --recursive https://github.com/google/woff2.git

cd woff2

make clean all

```

Alternatively, if Brotli is already installed on your system you can use CMake

to build executables and libraries:

```

git clone https://github.com/google/woff2.git

cd woff2

mkdir out

cd out

cmake ..

make

make install

```

By default, shared libraries are built. To use static linkage, do:

```

cd woff2

mkdir out-static

cmake -DBUILD_SHARED_LIBS=OFF ..

make

make install

```

## Run

Ensure the binaries from the build process are in your $PATH, then:

```

woff2_compress myfont.ttf

woff2_decompress myfont.woff2

```
