IJG describes itself as an informal group that writes and distributes a widely used free JPEG compression library, with the first version released on 7 October 1991. ### 项目历史 IJG's package grew around a portable C implementation of the JPEG standard, plus command-line tools such as `cjpeg`, `djpeg`, `jpegtran`, `rdjpgcom`, and `wrjpgcom`. Its README emphasizes portability, flexibility, and industrial-strength reuse rather than tutorial code, which explains why libjpeg became infrastructure rather than just a sample implementation. The package also became a baseline for later JPEG implementations and forks. libjpeg-turbo maintains a reference repository of IJG code for comparison and benchmarking, while the IJG reference site frames libjpeg as the technical basis of a media format that remains massively deployed. ### 采用历史 IJG libjpeg spread because it gave Unix, desktop, and embedded software a royalty-free way to read and write JPEG files. Package managers expose both the library and its small CLI utilities, making it a dependency of image viewers, converters, web tooling, and batch-processing scripts. The 6b ABI became especially important in distribution culture because many downstream projects and alternative implementations, including libjpeg-turbo and mozjpeg-compatible builds, preserved or targeted that interface. ### 使用方式 `cjpeg` and `djpeg` convert between JPEG and other image formats, `jpegtran` performs lossless transforms and transcoding, and `rdjpgcom`/`wrjpgcom` handle textual comments. Developers also link against libjpeg directly when adding JPEG support to applications. ### 为什么软件包爱好者会关心 For package maintainers, IJG JPEG is a canonical example of a tiny-looking formula that underpins a huge dependency graph. Its ABI history explains why distributions often care about which JPEG implementation satisfies `libjpeg` and why compatibility with IJG behavior still matters decades after the format became ordinary. ### 时间线 - 1991-10-07: IJG released the first version of its JPEG software. - 1998-03-27: IJG release 6b established a long-lived compatibility target for downstream libraries and tools. - 2024: The IJG reference site marked JPEG's 33rd anniversary and described ongoing libjpeg development. - 2026-01-25: IJG release 10 was published. ### Related projects - Related projects include libjpeg-turbo, mozjpeg, JPEG Club's IJG reference material, and the many CLI tools that build on libjpeg-compatible APIs. ### 来源 - - - ## 安全说明 没有找到 jpeg 的匹配本地密钥处理 manifest。Nucleus 软件包元数据仍在此发布，以便未来覆盖拥有稳定的软件包 URL。 ## 源数据库详情 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** jpeg - **Aliases:** libjpeg, libjpg - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** yes - **URL Keys:** stable ## 其他软件包管理器记录 - apk - jpeg - 9f-r0: normalized package name match | Alpine Linux edge package indexes: jpeg from https://dl-cdn.alpinelinux.org/alpine/edge/main/x86_64/APKINDEX.tar.gz | Wrapper for libjpeg-turbo | https://www.ijg.org/ - apk - jpeg-dev - 9f-r0: normalized package name match | Alpine Linux edge package indexes: jpeg-dev from https://dl-cdn.alpinelinux.org/alpine/edge/main/x86_64/APKINDEX.tar.gz | Wrapper for libjpeg-turbo-dev | https://www.ijg.org/ - apk - libjpeg - 9f-r0: normalized package name match | Alpine Linux edge package indexes: libjpeg from https://dl-cdn.alpinelinux.org/alpine/edge/main/x86_64/APKINDEX.tar.gz | Wrapper for libjpeg-turbo | https://www.ijg.org/ - zypper - libjpeg-turbo - 3.1.4.1-83.2: normalized package name match | openSUSE Tumbleweed package metadata: libjpeg-turbo from https://download.opensuse.org/tumbleweed/repo/oss/repodata/be8d3611d25469107f32075a1697e69ec57a2b850b42348a658cc671ad5ec2b50760d02c3e59524d50da9a11d5be799bdaffba2e166e8ca8858512e3c0bd665d-primary.xml.zst | A SIMD-accelerated library for manipulating JPEG image files | https://libjpeg-turbo.org/ - MacPorts - jpeg: normalized package name match | MacPorts ports tree: graphics/jpeg/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## 相关链接 - [Networking and protocol packages](https://www.automicvault.com/zh-hans/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Media and graphics packages](https://www.automicvault.com/zh-hans/pkg/media-graphics-tools/) - Matched media, image, audio, video, or graphics metadata. - [jpegtran-bin](https://www.automicvault.com/zh-hans/pkg/npm/jpegtran-bin/) - Executable or command metadata overlaps with this package.
