About formats

XPS (XML Paper Specification) is a fixed-layout document format developed by Microsoft, first released with Windows Vista and .NET Framework 3.0 in November 2006. Conceived as Microsoft's alternative to Adobe's PDF, XPS uses XML-based page description markup within a ZIP-based Open Packaging Conventions container. Each page is described as a FixedPage element containing paths (vector shapes with fill and stroke), glyphs (text positioned at precise coordinates), images, and canvas groupings — all specified with exact coordinates for pixel-precise rendering. The format embeds all required resources: fonts are subset and included, images are stored within the package, and the complete rendering specification travels with the document. Windows includes the XPS Document Writer as a virtual printer, allowing any application to generate XPS output through the standard print dialog. One advantage is exact visual fidelity — XPS documents render identically on any compliant viewer because every element is positioned absolutely, with no interpretation variance. Native Windows integration is another strength: XPS viewing, creation, and printing are built into Windows without additional software, and the .NET Framework provides APIs for programmatic XPS generation. While XPS did not achieve the ubiquity of PDF as a universal document format, it remains used in Windows printing infrastructure, enterprise document workflows, and scenarios where the Windows platform provides native end-to-end support.

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.
