プロジェクトの歴史

DjVu was originally developed at AT&T Labs-Research and was sold to LizardTech in March 2000. LizardTech released the reference implementation under the GNU GPL in October 2000, after which DjVuLibre continued as an enhanced open source version maintained by original DjVu inventors.

採用の歴史

The official DjVuLibre site describes DjVu as being used by hundreds of academic, commercial, governmental, and non-commercial sites, and lists distribution availability through Fedora, openSUSE, Debian, Ubuntu, Windows, and Mac OS packages.

使われ方

Package users get a broad command-line toolkit for creating, inspecting, assembling, extracting, decoding, and converting DjVu documents, plus the C++ DjVu reference library. The source README also notes that most users on macOS can install the Homebrew package directly.

パッケージ好きにとっての重要性

DjVuLibre matters in package collections because it is both an archival-document utility suite and the reusable library behind many DjVu workflows. It is the package that turns a historically web-centric scanned-document format into normal Unix command-line plumbing.
