About formats

PS is the standard extension for files written in PostScript, the page description language created by Adobe Systems and first shipped in 1984 with the Apple LaserWriter. A PostScript file is a complete program that describes the precise appearance of a page — text, vector graphics, curves, fills, and even embedded raster images — using a stack-based interpreted language with full programming constructs. When sent to a PostScript-compatible printer or interpreter (such as Ghostscript), the program executes and produces rendered output. PostScript introduced cubic Bezier curves as the standard representation for smooth outlines, a mathematical model that became the foundation for virtually all subsequent vector graphics and font technology including PDF, SVG, and OpenType. The language also serves as a font format: Type 1 PostScript fonts encode glyph outlines as PostScript programs with hinting instructions for sharp rendering at low resolutions, while Type 3 fonts use the full language to define arbitrarily complex glyphs. One advantage is device independence — a PostScript file produces identical output whether rendered on a 300 dpi desktop printer, a high-resolution imagesetter, or a software rasterizer, because it describes shapes mathematically rather than as pixel grids. The human-readable text format provides another practical strength: PS files can be inspected, debugged, and modified with any text editor, and they can be generated programmatically by any software without requiring specialized libraries. PostScript files are widely handled by Ghostscript, Adobe Acrobat, preview applications, and numerous publishing and graphics tools.

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.
