Style protobuf
We're encoding the styling information as a protocol buffer, according to proto/style.proto. The reason for doing so is that we don't have to ship with a JSON/yaml parser. To test the conversion script, run
bin/convert-style.js | protoc --decode=style proto/style.proto
You should see a nicely formatted hierarchical output of the converted style.
Usage
- Press 'R' to reset the transform
- Press 'N' to reset north
