About formats

G4 is a monochrome image format based on the ITU-T Group 4 facsimile coding standard (Recommendation T.6), ratified by the CCITT in 1984 as an improvement over Group 3 for use on error-free digital networks like ISDN rather than analog telephone lines. G4 files contain 1-bit image data compressed using exclusively two-dimensional Modified Modified READ (MMR) coding, where each scanline is encoded as a set of differences (changing elements) relative to the line above it. By eliminating the one-dimensional coding fallback and the end-of-line synchronization markers required by Group 3, G4 achieves 20-50% better compression ratios on typical document pages while producing a simpler, more regular bitstream. The format is most commonly encountered as a compression method within TIFF files (TIFF compression tag 4), where it became the standard archival format for scanned documents in enterprise document management, government records, and legal imaging systems. G4 compression is specified at 200, 300, or 400 dpi depending on the scanning application, with 300 dpi being the most common for archival-quality document imaging. One advantage is exceptional compression efficiency for document content: G4's two-dimensional prediction exploits the strong vertical correlation in text and line art pages, typically compressing a 300 dpi letter-size page to 30-50 KB — roughly half the size of equivalent Group 3 encoding. The format's entrenchment in document management infrastructure is another strength — G4 TIFF is the mandated format for many government digital records systems, court filing systems, and corporate archives, supported by every enterprise imaging platform.

AW is the document format of Applix Words, the word processor component of the Applix office suite (later renamed Anyware Office) developed by Applix, Inc. for Unix and Linux workstations. The suite targeted enterprise Unix environments during the 1990s, providing word processing, spreadsheet, graphics, and presentation capabilities on platforms like Solaris, HP-UX, AIX, and Linux where Microsoft Office was unavailable. AW files store formatted text documents with support for character and paragraph styling, page layout, tables, headers and footers, and embedded graphics. The format uses a proprietary binary structure optimized for the Applix application's internal document model. Applix Words gained particular visibility in the Linux community during the late 1990s when it was bundled with several commercial Linux distributions as their default word processor before OpenOffice.org became widely available. One advantage was native Unix platform support — Applix provided professional word processing capabilities on Unix workstations at a time when few commercial alternatives existed. The format's tight integration with other Applix suite components enabled cross-referencing between word processing documents, spreadsheets, and presentations. Applix was acquired by Cognos in 2003, and the office suite was discontinued. AW files are primarily encountered today in archived documents from Unix enterprise environments of the 1990s and early 2000s.
