It described nbimg as a command-line HTC splash screen tool that could convert NB to BMP and BMP to NB, autodetect image dimensions, support any splash screen size, and handle devices such as the Diamond and Athena at 640x480. The GitHub repository was created on 2012-06-18 and now mainly preserves the source and download references. The repository tags include v1.1, v1.2, and v1.2.1; there are no GitHub Releases listed by the releases API. ### Adoption history This is a preservation-and-specialist package, not a broad developer tool. GitHub API data retrieved on 2026-07-01 showed 10 stars and 6 forks, and Homebrew Formulae reported only 8 installs over the prior 365 days. Its practical audience is people working with old smartphone firmware images or boot splash customization workflows where NB, BMP, or NBH splash formats still appear. ### How it is used The original CLI takes -F with a .nb or .bmp file; a BMP input is encoded to NB, and an NB input is decoded to BMP. Optional flags set width, height, padding pattern, padding size, smartphone output mode, and NBH metadata such as model ID and header type. Package users install it when they need exactly that file-format bridge. There is little sign of a modern ecosystem around it beyond keeping the converter buildable and packaged. ### Why package nerds care nbimg is useful mostly as a format fossil: tiny, specific, and still installable through Homebrew for the rare case where old mobile boot-splash tooling is needed. ### Timeline - 2008-07-03: original nbimg HTC splash screen tool post published. - 2012-06-18: poliva/nbimg repository created on GitHub. - 2019-09-24: latest GitHub push date reported by the GitHub API retrieval on 2026-07-01. - 2026-07-01: Homebrew Formulae reported stable version 1.2.1. ### 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:** nbimg - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Source-control packages](https://pkg.so/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://pkg.so/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://pkg.so/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://pkg.so/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [libimobiledevice](https://pkg.so/brew/libimobiledevice/) - Shares pkgdb curated category or tags: cli, developer-tools, mobile. - [mobiledevice](https://pkg.so/brew/mobiledevice/) - Shares pkgdb curated category or tags: cli, developer-tools, mobile. - [eas-cli](https://pkg.so/brew/eas-cli/) - Shares pkgdb curated category or tags: cli, developer-tools, mobile. - [cyan](https://pkg.so/brew/cyan/) - Shares pkgdb curated category or tags: cli, developer-tools, mobile. - [apktool](https://pkg.so/brew/apktool/) - Shares pkgdb curated category or tags: android, cli, developer-tools. - [go-md2man](https://pkg.so/brew/go-md2man/) - Shares pkgdb curated category or tags: cli, converter, developer-tools. - [bundletool](https://pkg.so/brew/bundletool/) - Shares pkgdb curated category or tags: android, cli, developer-tools. - [repo](https://pkg.so/brew/repo/) - Shares pkgdb curated category or tags: android, cli, developer-tools. - [react-native-bootsplash](https://pkg.so/npm/react-native-bootsplash/) - Local package facts share a topical domain.
