## Project history and usage

nbimg is a very small boot-splash conversion utility for older HTC, Android, and Windows CE smartphone images, converting between NB splash-screen files and BMP images.

### Project history

The original release post was published on 2008-07-03 by Pau Oliva. 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.
