Rust bindings for TurboJPEG, which provides simple and fast compression/decompression of JPEG images.
TurboJPEG is a high-level API provided by [libjpeg-turbo].
To quickly encode and decode images from the image crate, add this
to the [dependencies] section in your Cargo.toml:
turbojpeg = {version = "0.2", features = ["image"]}
and then use the functions turbojpeg::decompress_image and
turbojpeg::compress_image. For more details, please see the
documentation.
The low-level binding to libturbojpeg is provided by the crate
turbojpeg-sys, which needs:
bindgen.rustc will use to link against libturbojpeg.By default, the turbojpeg-sys crate uses a pregenerated Rust binding code (so
you don't need the C headers) and the default linker flags -l turbojpeg.
However, this behavior can be altered in several ways:
pkg-config uses the pkg-config tool to find the linker flags
and the include paths for C headers that are specific for your system.TURBOJPEG_INCLUDE_PATH, if specified, adds an extra
include path for C headers.bindgen uses the bindgen tool to generate Rust binding code
at build time, instead of using the pregenerated code. If no include paths
are specified (using pkg-config or TURBOJPEG_INCLUDE_PATH), we use
headers that are bundled with turbojpeg-sys.All this magic is implemented in the build.rs script in turbojpeg-sys. If
you think that it could be improved, or if you encounter an error on your
system, please open an issue or a pull request.
All contributions are welcome! Please contact me (@honzasp) or open a pull request. This crate is rather minimal, the main areas of improvement are:
turbojpeg crate.turbojpeg-sys crate, so that it works
seamlessly on a wide range of systems.This is free and unencumbered software released into the public domain.
