About formats

FIG is the native file format of Xfig, a free vector graphics editor for the X Window System, originally written by Supoj Sutanthavibul at the University of Texas at Austin in 1985. The format uses a plain-text structure where each graphic object is described on one or more lines with numeric parameters specifying object type, coordinates, line properties, fill attributes, and depth ordering. FIG supports compound objects (groups), polylines, polygons, splines, arcs, ellipses, text strings, and imported bitmaps, each with configurable colors, line styles, arrow heads, and area fills. Files begin with a header line declaring the format version (currently 3.2), followed by a resolution specification and the object definitions. One advantage is exceptional simplicity — the entirely text-based format is trivially parsed, generated, and manipulated by scripts, making FIG popular as an intermediate format in automated diagram generation pipelines. The rich ecosystem of conversion tools is another strength: fig2dev exports FIG files to dozens of output formats including EPS, PDF, SVG, LaTeX picture environments, PSTricks, and TikZ. This made Xfig and FIG especially popular in academic and scientific communities, where authors generate publication-quality figures that integrate seamlessly with LaTeX documents. While graphical tools have evolved since the 1980s, FIG remains in use among researchers who value its scriptability, LaTeX integration, and well-documented format stability.

RB is the native ebook format of the Rocket eBook, one of the first commercially available dedicated e-reading devices, developed by NuvoMedia and released in October 1998. Founded by Martin Eberhard and Marc Tarpenning — who later co-founded Tesla Motors — NuvoMedia designed the Rocket eBook as a handheld device with a reflective LCD screen, capable of storing approximately ten books in its internal memory. The RB format packages HTML-based content along with embedded images, metadata, and a table of contents into a single binary container optimized for the device's limited hardware. Content was purchased and downloaded through NuvoMedia's RocketLibrarian desktop software. A notable advantage of the format was its early support for bookmarking, annotation, dictionary lookups, and adjustable font sizing — features now standard on modern e-readers but revolutionary in the late 1990s. The Rocket eBook demonstrated viable commercial demand for dedicated reading devices, paving the way for subsequent platforms from Sony, Amazon, and others. NuvoMedia was acquired by Gemstar-TV Guide International in 2000, which discontinued the device line in 2003. While RB files are largely a historical curiosity today, they can be converted to modern formats using ebook management tools, and the format remains significant as a pioneering chapter in the evolution of digital reading.
