The upstream README describes hqx as a fast, high-quality magnification filter designed for pixel art. ### Projektgeschichte The grom358 implementation packages Maxim Stepin's hqx pixel-art scaling family as a buildable Unix library and CLI. Its NEWS file says version 1.0 added 24-bit color support, a command-line tool using the DevIL image library, and an autotools build system. The README explains the algorithmic shape: each source pixel is evaluated against its 3-by-3 neighborhood, color differences are calculated in YUV space, a 256-entry lookup table selects interpolation patterns, and the result preserves sharp edges better than nearest-neighbor scaling for sprites and line art. ### Adoptionsgeschichte The README ties hqx to emulator culture, naming Nestopia, bsnes, ZSNES, Snes9x, and FCE Ultra as users of the algorithm family. Homebrew and Fedora packaging make the grom358 library/CLI available outside emulator source trees. ### Wie es verwendet wird The documented CLI usage is `hqx -s scaleBy input output`, where the scale is 2, 3, or 4. The library API exposes functions such as `hq4x_32` after `hqxInit()`, allowing applications to scale RGB bitmaps directly. The filter is intended for images with sharp edges, such as pixel art, line graphics, and cartoon sprites, rather than photographs. ### Warum Paket-Nerds sich dafür interessieren hqx matters because it packages a once-emulator-specific graphics algorithm as a reusable system library and filter command. That is exactly the sort of niche media primitive package managers keep alive: small, old-school, useful when you need it, and awkward to rederive from scratch. Its significance is also historical: hq2x/hq3x/hq4x belong to the era when emulator authors competed to make low-resolution console graphics look acceptable on higher-resolution displays without losing pixel-art structure. ### Zeitleiste - 2001-2002: Archived HiEnd3D hq2x material carries Maxim Stepin copyright dates. - 1.0: The grom358 NEWS file records 24-bit color support, the DevIL-based command-line tool, and autotools build support. - 1.2: Homebrew packages the grom358 hqx implementation as version 1.2. ### Related projects - hq2x, hq3x, and hq4x are the three scaling filters implemented by the package. - DevIL is the image library required by the documented command-line build. - Nestopia, bsnes, ZSNES, Snes9x, and FCE Ultra are emulator projects named in the upstream README as users of the hqx algorithm family. - Scale2x and 2xSaI are neighboring pixel-art scaling algorithms shown alongside hq2x in preserved HiEnd3D comparison material. ### Quellen - - - - ## Sicherheitshinweise narrow executable package without higher-risk signals. - **Geiger-Risiko:** grün / niedrig - narrow executable package without higher-risk signals ## Details aus der Quelldatenbank - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** hqx - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Andere Paketmanager-Einträge - dnf - hqx - 1.2-13.fc44: normalized package name match | Fedora Rawhide package metadata: hqx from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | High quality upscaling program for pixel-art | https://github.com/grom358/hqx - dnf - libhqx - 1.2-13.fc44: normalized package name match | Fedora Rawhide package metadata: libhqx from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | High quality upscaling library for pixel-art | https://github.com/grom358/hqx - dnf - libhqx-devel - 1.2-13.fc44: normalized package name match | Fedora Rawhide package metadata: libhqx-devel from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | Development files for libhqx | https://github.com/grom358/hqx ## Verwandte Links - [Source-control packages](https://www.automicvault.com/de/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/de/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/de/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Media and graphics packages](https://www.automicvault.com/de/pkg/media-graphics-tools/) - Matched media, image, audio, video, or graphics metadata. - [autoconf](https://www.automicvault.com/de/pkg/brew/autoconf/) - Build dependency declared by Homebrew. - [automake](https://www.automicvault.com/de/pkg/brew/automake/) - Build dependency declared by Homebrew. - [libtool](https://www.automicvault.com/de/pkg/brew/libtool/) - Build dependency declared by Homebrew. - [pkgconf](https://www.automicvault.com/de/pkg/brew/pkgconf/) - Build dependency declared by Homebrew. - [camellia](https://www.automicvault.com/de/pkg/brew/camellia/) - Shares av.db curated category or tags: c-library, cli, image-processing, media. - [gdk-pixbuf](https://www.automicvault.com/de/pkg/brew/gdk-pixbuf/) - Shares av.db curated category or tags: c-library, cli, image-processing, media. - [imageworsener](https://www.automicvault.com/de/pkg/brew/imageworsener/) - Shares av.db curated category or tags: cli, image-processing, image-scaling, media. - [leptonica](https://www.automicvault.com/de/pkg/brew/leptonica/) - Shares av.db curated category or tags: c-library, cli, image-processing, media. - [babl](https://www.automicvault.com/de/pkg/brew/babl/) - Shares av.db curated category or tags: cli, image-processing, media. - [caire](https://www.automicvault.com/de/pkg/brew/caire/) - Shares av.db curated category or tags: cli, image-processing, media. - [chafa](https://www.automicvault.com/de/pkg/brew/chafa/) - Shares av.db curated category or tags: cli, image-processing, media. - [dssim](https://www.automicvault.com/de/pkg/brew/dssim/) - Shares av.db curated category or tags: cli, image-processing, media. - [glyph](https://www.automicvault.com/de/pkg/brew/glyph/) - Both packages work with overlapping file formats or content types.
