- Leipzig is Verovio's own font.
- Bravura is designed by Daniel Spreadbury.
- Gootville is designed by Grzegorz Pruchniakowski and comes with MuseScore.
- Petaluma is designed by Steinberg.
- Leland is designed by MuseScore (3.6).
All fonts included in Verovio are licensed under the SIL Open Font License.
The generate.py script is a utility for working with font files and preparing them for Verovio. Calling it with the
--help argument will list the possible sub-commands and options for working with the font files.
To extract the fonts, the svgpathtools module is required to exist in your Python environment.
To generate the css, woff2, and svg fonts you should have fontforge installed. The script will try to
auto-detect the path to fontforge, but you can also pass a path to the binary directly with the --fontforge argument.
If you are having problems, you can pass the --debug parameter, which will increase the verbosity of the script.
Included are the necessary files to install a Python poetry-managed virtual environment. If you do not wish to use
these you may ignore them. You should make sure you have Poetry installed and then
run poetry install from this directory. poetry shell will then allow you to interact with the script using
the virtual environment.
You may run into problems installing numpy and/or scipy when installing svgpathtools on a Mac using Homebrew, where it will complain of not being able to find LAPACK/BLAS.
To fix this try:
brew install openblas lapack
export LDFLAGS="-L/opt/homebrew/opt/lapack/lib"
export LDFLAGS="-L/opt/homebrew/opt/lapack/include"
export CPPFLAGS="-L/opt/homebrew/opt/lapack/include"
export PKG_CONFIG_PATH="-L/opt/homebrew/opt/lapack/pkgconfig"
export CFLAGS=-Wno-error=implicit-function-declaration
export LAPACK=/opt/homebrew/opt/lapack/lib/liblapack.dylib
export BLAS=/opt/homebrew/opt/openblas/lib/libopenblas.dylibAfter that, re-run poetry install and it should work.
Contributions are welcome. Please ensure you run the mypy and black utilities on any Python code submitted.
