About formats

DST (Tajima) is a machine embroidery file format created by Tajima Industries, one of the world's leading manufacturers of commercial embroidery equipment. The format encodes stitch data as a sequence of relative coordinate movements, with each stitch record containing a horizontal offset, vertical offset, and a command flag indicating the stitch type — normal stitch, jump (move without stitching), color change, or stop. DST files use a compact binary encoding where each stitch occupies three bytes, making the format efficient for storing complex multi-color designs with tens of thousands of stitches. The coordinate system uses 0.1 mm increments with a maximum single-stitch length of 12.1 mm in any direction. DST has become the de facto standard in the commercial embroidery industry — virtually every embroidery machine from any manufacturer can read DST files, making it the most widely supported embroidery format in existence. One advantage is universal machine compatibility: a DST file will run reliably on Tajima, Barudan, SWF, Brother, and Melco machines alike, eliminating format conversion concerns. The minimal file structure is another strength — files are compact, load instantly even on older machine controllers with limited memory, and their simplicity makes them resistant to corruption during transfer. While DST lacks embedded metadata like thread color names and design previews, this limitation is offset by the format's unmatched portability across the global embroidery industry.

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.
