This library provides C bindings and an API for encoding Webp images using Google's libwebp.

It is based on go-webp, but this includes and builds the libwebp C source from a versioned Git subtree.

Update libwebp version

1. Pull in the relevant libwebp version, e.g. ./pull-libwebp.sh v1.2.0
2. Regenerate wrappers with go generate ./gen
3. Update the libwebp version badge above.

Local development

Compiling C code isn' particulary fast; if you install libwebp on your PC you can link against that, useful during development.

On a Mac you may do something like:

brew install webp
go test ./libwebp -tags dev
