Its README describes the core idea as using libjpeg's ability to decode only the DCT coefficients needed for the requested output size, reducing CPU work when large JPEGs are turned into small thumbnails. ### Project history The epeg README says the library was originally developed inside the Enlightenment project. The repository maintainer notes that at some later, unspecified point epeg disappeared from that project or was merged into another library, with v0.9.1.042 named as the last original version known to that maintainer. The current GitHub repository preserves that original code lineage while carrying updates and improvements on the master branch. The copyright notice dates the software to 2000 and credits Carsten Haitzler and contributors. ### Adoption history epeg stayed a niche but memorable package because it solved one job well: quickly making thumbnails from JPEGs. It accumulated language bindings for Python and Node.js and enough downstream interest to remain packaged in Homebrew, MacPorts, and Nix. ### How it is used Users and bindings rely on epeg when the source image is much larger than the desired thumbnail. The performance advantage comes from avoiding full-resolution decode work and, in some cases, avoiding colorspace conversion when YUV or grayscale access is sufficient. ### Why package nerds care epeg is the sort of package that appeals to people who like small, purpose-built C libraries: it wraps a particular libjpeg optimization in a compact API and command-line install, and it carries a visible lineage from desktop-environment infrastructure into modern package managers. ### Timeline - 2000: Copyright notice credits Carsten Haitzler and contributors. - Unknown: epeg developed within the Enlightenment project. - Unknown: epeg disappeared from or was merged into another Enlightenment library after the original line. - 2023-04-05: GitHub release epeg v0.9.3 published. ### Related projects - epeg relates to libjpeg, the Enlightenment project, Python bindings through epeg-cffi, and Node.js bindings distributed as an npm package. ### Sources - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** epeg - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - epeg: normalized package name match | nixpkgs package indexes: pkgs/by-name/ep/epeg/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - MacPorts - epeg: normalized package name match | MacPorts ports tree: graphics/epeg/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Media and graphics packages](https://www.automicvault.com/pkg/media-graphics-tools/) - Matched media, image, audio, video, or graphics metadata. - [jpeg-turbo](https://www.automicvault.com/pkg/brew/jpeg-turbo/) - Runtime dependency declared by Homebrew. - [autoconf](https://www.automicvault.com/pkg/brew/autoconf/) - Build dependency declared by Homebrew. - [automake](https://www.automicvault.com/pkg/brew/automake/) - Build dependency declared by Homebrew. - [libtool](https://www.automicvault.com/pkg/brew/libtool/) - Build dependency declared by Homebrew. - [dezoomify-rs](https://www.automicvault.com/pkg/brew/dezoomify-rs/) - Shares av.db curated category or tags: cli, images, media. - [exiftran](https://www.automicvault.com/pkg/brew/exiftran/) - Shares av.db curated category or tags: cli, image-processing, jpeg, media. - [gd](https://www.automicvault.com/pkg/brew/gd/) - Shares av.db curated category or tags: cli, image-processing, jpeg, media. - [imgdiet](https://www.automicvault.com/pkg/brew/imgdiet/) - Shares av.db curated category or tags: cli, images, media. - [imgp](https://www.automicvault.com/pkg/brew/imgp/) - Shares av.db curated category or tags: cli, images, media. - [imgproxy](https://www.automicvault.com/pkg/brew/imgproxy/) - Shares av.db curated category or tags: cli, images, media. - [babl](https://www.automicvault.com/pkg/brew/babl/) - Shares av.db curated category or tags: cli, image-processing, media. - [caire](https://www.automicvault.com/pkg/brew/caire/) - Shares av.db curated category or tags: cli, image-processing, media. - [jp2a](https://www.automicvault.com/pkg/brew/jp2a/) - Both packages work with overlapping file formats or content types.
