About formats

WPS is the document format of Microsoft Works, an integrated productivity suite first released in 1987 that bundled a word processor, spreadsheet, and database in a single affordable application. The WPS format stores word processing documents in a compact binary structure that encodes text content, character and paragraph formatting, page layout, headers, footers, and embedded images. Microsoft positioned Works as a consumer-grade alternative to the more expensive and feature-rich Microsoft Office, pre-installing it on millions of OEM personal computers throughout the 1990s and 2000s. This widespread bundling made WPS one of the most commonly encountered document formats in the consumer PC market, even though many users were unaware they were not using "full" Microsoft Word. The format supports basic word processing features including fonts, text alignment, indentation, bulleted and numbered lists, tables, and page formatting, but lacks advanced capabilities like tracked changes, macros, and complex styles found in DOC. One advantage was accessibility — Microsoft Works cost a fraction of Office's price and came free with many PCs, providing capable word processing to millions of home users and students who did not need enterprise features. Microsoft discontinued Works in 2009, recommending migration to Word or the free Office Online tools. WPS files remain present in personal document archives from that era and can be opened by LibreOffice and older versions of Microsoft Office.
Developer: Microsoft
Initial release: 1987
PGX is a simple single-component raster image format defined as part of the JPEG 2000 standard (ISO/IEC 15444) for use in conformance testing and verification of JPEG 2000 codec implementations. Introduced around 2000 alongside the JPEG 2000 specification itself, PGX files store a single image component (one color channel or grayscale plane) with a text header followed by raw pixel data, providing an unambiguous reference representation against which encoder and decoder outputs can be compared sample by sample. The header is a single ASCII line specifying endianness (ML for big-endian, LM for little-endian), signedness (+ for unsigned, - for signed), bit depth (1 to 32 bits), width, and height. The pixel data follows as raw binary values, each occupying the minimum number of bytes needed for the specified bit depth, with one value per pixel. For multi-component images (like RGB), each component is stored in a separate PGX file. The format's deliberate simplicity — no compression, no metadata, no multi-channel support — ensures there are no ambiguities in interpretation that could mask codec bugs. One advantage is verification precision: PGX's uncompressed, exactly-specified representation allows bit-exact comparison of decoded JPEG 2000 output against reference images, essential for certifying that a codec implementation conforms to the standard. The format's role in the JPEG 2000 conformance testing framework means it is implemented by every serious JPEG 2000 codec (OpenJPEG, Kakadu, etc.) and used in the official ISO conformance test suite. PGX files can also be processed by ImageMagick and various JPEG 2000 development tools.
