About formats

EPS (Encapsulated PostScript) is a vector file format developed by Adobe Systems in collaboration with Aldus Corporation, first published in 1987. Built on Adobe's PostScript page description language, EPS wraps a self-contained PostScript program describing a single page of graphics — including vector paths, text, and embedded raster images — within a structured comment framework that provides bounding box coordinates and optional preview thumbnails. The encapsulation allows an EPS file to be placed into another document as a contained graphic element without interfering with the host document's PostScript code. For decades, EPS served as the universal exchange format in professional publishing, prepress, and print production, accepted by virtually every design, illustration, and page layout application across platforms. One key advantage is print-industry reliability — because EPS contains device-independent PostScript instructions, output is consistent across different RIPs, imagesetters, and printing presses. The format's cross-application compatibility is another strength: an EPS file created in Illustrator, CorelDRAW, or Inkscape can be placed in QuarkXPress, InDesign, or Word without requiring the originating application. While PDF has largely superseded EPS for modern workflows, the format remains widely used in stock illustration libraries, legacy publishing pipelines, and any context requiring a proven, universally supported vector exchange format.

TCR (Text Compression for Reader) is a compressed plain-text ebook format developed by Barry Childress in the early 1990s for the Psion Series 3 family of palmtop computers. The format was created for Childress's Reader3 application, a text file viewer that needed to fit large books into the Psion's extremely limited storage — typically 128 KB to 2 MB of available memory. TCR uses a dictionary-based compression scheme derived from the earlier ZVR format by Ian Giddings, replacing repeated byte sequences with single-byte tokens that reference a header dictionary. This straightforward approach achieves compression ratios of roughly 40-60% on typical English prose while requiring minimal CPU resources for decompression. The Psion Series 3 ran on a 3.84 MHz NEC V30 processor with no floating-point unit, so TCR's low computational overhead was essential for smooth page-by-page reading. A key advantage is remarkable storage efficiency for its simplicity — users could carry dozens of novels on removable SSD cards that held only a few hundred kilobytes. The format found a dedicated user community among Psion enthusiasts who built libraries of compressed literature for portable reading years before smartphones existed. Though the Psion platform faded from the market in the early 2000s, TCR files can still be opened and converted by modern ebook tools, and the format stands as an early example of purpose-built mobile reading technology from the pre-smartphone era.
