Thanks. However, it seems not to be as 'open source' as advertised: The file https://gitlab.com/vgg/image-compare/-/blob/main/app/js/transform.js mostly consists of a huge binary WASM blob, without any hints where this comes from and what it does... Anyway, AFAICS, it doesn't provide what we need for LilyPond. Werner
