软件包摘要
Magnification filter designed for pixel art
历史
项目历史与用法
hqx is a C library and command-line tool for the hq2x, hq3x, and hq4x pixel-art scaling filters. The upstream README describes hqx as a fast, high-quality magnification filter designed for pixel art.
项目历史
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.
采用历史
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.
使用方式
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.
为什么软件包爱好者会关心
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.
时间线
- 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.
