About formats

TIFF (Tagged Image File Format) is a flexible raster image format originally developed by Aldus Corporation (later acquired by Adobe) in October 1986 for desktop publishing and scanning applications. The format uses a tagged data structure where the image file header points to one or more Image File Directories (IFDs), each containing a set of tags that describe the image's dimensions, color space, compression, resolution, and other properties. This extensible architecture means TIFF can accommodate virtually any image type: 1-bit bilevel, grayscale, indexed color, RGB, CMYK, CIE L*a*b*, and beyond, at any bit depth from 1 to 64 bits per sample. TIFF supports multiple compression methods including none (uncompressed), LZW, DEFLATE, JPEG, and CCITT Group 3/4 fax compression, as well as multi-page documents, tiled storage for efficient random access to large images, and floating-point pixel values for HDR content. One advantage is professional-grade flexibility — TIFF handles the full range of image types encountered in publishing, prepress, medical imaging, geospatial analysis, and scientific research, where specialized color spaces and high bit depths are required. Lossless archival quality is another core strength: TIFF with no compression or LZW/DEFLATE preserves every pixel value exactly, making it the standard archival format for libraries, museums, and any institution that requires guaranteed long-term image fidelity. TIFF is supported by every major image editing, scanning, and publishing application across all platforms.

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.
