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.

PGM (Portable Graymap) is the grayscale member of the Netpbm image format family, created by Jef Poskanzer in 1988 as part of the Pbmplus toolkit for Unix systems. PGM stores single-channel intensity images where each pixel holds a gray value from 0 (black) to a user-specified maximum (typically 255 for 8-bit or 65535 for 16-bit). The format exists in ASCII (magic number P2), where pixel values are written as decimal text numbers separated by whitespace, and binary (magic number P5), where values are stored as raw bytes. Both variants begin with a header specifying the magic number, width, height, and maximum gray value. PGM was designed as the grayscale intermediate in Netpbm's convert-process-convert pipeline philosophy: source images from any format are converted to PGM, processed using Netpbm's extensive command-line tool library, then converted to the target format. One advantage is format transparency — the ASCII variant makes image data directly readable by humans and trivially processable by text tools like awk and grep, invaluable for debugging and education. The scientific and computer vision community's adoption is another strength: PGM's straightforward single-channel representation makes it a natural format for image analysis algorithms, and many academic papers and course materials use PGM examples. The format is supported by ImageMagick, GIMP, and countless image processing libraries, and remains standard input for many research tools and benchmarks.
