# `jpegxl-sys`
`jpegxl-sys` provides a wrapper for the `libjxl` library.
For more details, refer to the [original library](https://github.com/libjxl/libjxl).
## Building
If you wish to specify a custom library path, set the `DEP_JXL_LIB` environment variable.
To build `libjxl` and statically link it, use the `vendored` feature.
## Usage
Check out testing units in `src/lib.rs` for some examples.
### Multi-thread
Because `libjxl_threads` uses `std::thread`, if you build and statically link `libjxl`, you need to
dynamically link to `libc++` or `libstdc++`.
Using the dynamic library doesn't need this step.
