About formats

DOC is the binary document format of Microsoft Word), the word processor first released in October 1983 for MS-DOS and later becoming the dominant document creation tool worldwide. The format stores documents as OLE2 compound document files — a binary container with multiple internal streams holding text content, formatting information, embedded objects, macros, and metadata. The text stream uses a complex system of formatting runs, section descriptors, paragraph and character property tables, and style definitions to represent arbitrarily complex document layouts including columns, headers, footnotes, tables, floating images, tracked changes, and mail merge fields. The format evolved substantially through Word versions, with Word 97 establishing the binary structure that remained standard through Word 2003 and created the .doc files most commonly encountered today. One advantage is near-universal compatibility — DOC files can be opened by virtually every word processor and document viewer across all platforms, from Microsoft Office to LibreOffice, Google Docs, and Apple Pages. The format's rich feature support is another strength: DOC handles complex layouts, embedded OLE objects, VBA macros, and revision tracking that power enterprise document workflows. Although Microsoft introduced the XML-based DOCX format with Office 2007, DOC remains heavily present in existing document archives and continues to be produced by organizations maintaining compatibility with older Word installations.

PNM (Portable Any Map) is an umbrella designation within the Netpbm family that encompasses all three classic portable map formats: PBM (Portable BitMap for monochrome), PGM (Portable GrayMap for grayscale), and PPM (Portable PixMap for color). Created by Jef Poskanzer in 1988 as part of the Pbmplus toolkit, PNM is not a distinct format with its own magic number but rather a collective name indicating that any of the three underlying formats may be used. When software reads a PNM file, it examines the magic number (P1/P4 for PBM, P2/P5 for PGM, P3/P6 for PPM) and processes accordingly; when software writes a PNM file, it selects the most appropriate subformat based on the image content. This convention allows Netpbm processing pipelines to pass images between tools without requiring the user to track which specific format is in use — every tool in the chain accepts PNM input and produces PNM output, with the actual format chosen automatically. The Netpbm toolkit provides hundreds of command-line utilities for image manipulation: scaling, rotation, color adjustment, compositing, format conversion, quantization, and analysis — all operating on PNM as the common interchange format. One advantage is pipeline composability: Netpbm tools can be chained with Unix pipes (e.g., pnmflip | pnmscale | ppmquant | ppmtogif) to build complex image processing operations from simple primitives, following the Unix philosophy of small, focused tools. The format family's cross-platform availability and language support is another strength — virtually every image processing library in every programming language can read and write PNM variants. PNM files are supported by ImageMagick, GIMP, and all major image tools.
