概要

パッケージ概要

JBIG2 decoder and library (for monochrome documents)

コマンドとエイリアス

  • jbig2dec

履歴

プロジェクトの歴史と使われ方

jbig2dec is a decoder library and command-line utility for the JBIG2 bi-level image compression format, also known as ITU T.88 and ISO/IEC 14492. Its practical niche is decoding monochrome scanned-document images, including JBIG2 streams embedded in PDF files.

プロジェクトの歴史

The project README describes jbig2dec as a decoder library and example utility, with development source kept in the Ghostscript Git repository and a GitHub mirror under ArtifexSoftware. The README also notes that the GitHub repository is a mirror and that releases are hosted through GitHub tags.

The SourceForge project page records that jbig2dec is no longer hosted there and points users to Ghostscript. That migration reflects the project's place in the Artifex/Ghostscript ecosystem, where JBIG2 decoding is part of broader PDF and page-description-language handling.

採用の歴史

The input metadata shows packaging across Homebrew, Alpine, Debian/Ubuntu, Fedora, MacPorts, Nix, Arch, and openSUSE. That broad packaging footprint matches a small C utility/library whose value is mostly as infrastructure for document conversion, PDF processing, and image decoding stacks.

使われ方

The command can decode a single JBIG2 stream to PNG or PBM output, or accept separate global and page streams used by embedded PDF organization. The man page documents diagnostic, dump, hash, quiet, verbose, and output-format options, while the README says the decoder remains useful in limited contexts and requests problematic files for testing.

パッケージ好きにとっての重要性

jbig2dec is the kind of compact media package that earns its place by handling one difficult format well enough for bigger tools to depend on it. It is especially relevant to PDF pipelines because JBIG2 is referenced by PDF 1.4 and later, and because scanned monochrome documents can achieve very high compression ratios.

タイムライン

  • SourceForge era: jbig2dec is hosted as a standalone open-source project.
  • Ghostscript era: Project hosting moves away from SourceForge and into the Ghostscript/Artifex ecosystem.
  • 2023: The man page identifies version 0.20 and documents the command-line interface.
  • Packaging era: Major Unix-like package managers carry jbig2dec as a small media/decoder dependency.

Related projects

  • jbig2dec is related to JBIG2, ITU T.88, ISO/IEC 14492, PDF 1.4 and later, Ghostscript, Artifex, MuPDF, scanned-document compression, PNG, and PBM output tooling.
