Debian with otfcc, otfcc-cubic2quad installed.
docker run --rm -v "$(pwd):/root" -it jamesits/otfcc-dev:latest bash
Preinstalled programs:
otfccdump
: dump font to JSONotfccbuild
: build font from JSONotfcc-c2q
: convert CFF OTF to TTFkaigen-otf2ttf
: the script used to build m13253/kaigen-fonts
System requirements:
- The programs use only one core, so go for some less-core higher-frequency CPUs
- >12GB free RAM needed to convert SourceSanHans series (16GB is recommended)
- 3GB free disk space to store temporary files
- and a lot cups of tea to fill yourself while waiting (no, don't drink Java)
