About formats

WMZ is a compressed variant of the Windows Metafile (WMF) format, introduced by Microsoft with Office 2000 in 1999. A WMZ file is simply a WMF file compressed using the gzip algorithm (RFC 1952), reducing the file size for more efficient storage and embedding within Office documents, web pages, and other containers. The underlying WMF format stores vector graphics as a sequence of GDI (Graphics Device Interface) function calls — commands that draw lines, curves, polygons, text, and bitmaps — recorded in a device-independent format that can be replayed at any resolution. WMZ preserves this vector nature: when decompressed, the file produces a standard WMF that renders through the Windows GDI subsystem using the same drawing primitives as on-screen display, ensuring visual fidelity across different output devices and resolutions. WMZ files are commonly found embedded in Microsoft Office documents (Word, Excel, PowerPoint), HTML email messages generated by Outlook, and web content produced by Office's Save as Web Page feature. The format is also used for clip art and template graphics distributed with Office installations. One advantage is space efficiency: gzip compression typically reduces WMF file sizes by 60-80%, meaningful when many small graphics are embedded in a single document or web page. The format's deep integration with the Microsoft Office ecosystem is another practical strength — WMZ graphics render natively in all Office applications without additional software, and can be extracted, decompressed, and converted using tools like LibreOffice, ImageMagick, Inkscape, and standard gzip utilities.

PBM (Portable Bitmap) is the monochrome (black and white, 1-bit) member of the Netpbm family of image formats, created by Jef Poskanzer in 1988 as part of the Pbmplus toolkit for Unix systems. The format exists in two variants: ASCII (magic number P1), where each pixel is represented as a text character '0' (white) or '1' (black) separated by whitespace, and binary (magic number P4), where pixels are packed eight per byte for compact storage. Both variants begin with a plain-text header specifying the magic number, image width and height, and optional comments. PBM was designed as the simplest possible image format — a bridge format for converting between the many incompatible raster formats that proliferated across different Unix systems and applications during the 1980s. The Netpbm philosophy was to convert any source format to PBM/PGM/PPM as an intermediate step, then convert to the target format, using the portable formats as a universal exchange layer. One advantage is extreme simplicity — the ASCII variant can be literally typed by hand in a text editor, and both variants are trivial to parse and generate in any programming language without external libraries. The format's role as a universal image processing intermediate is another strength: hundreds of Netpbm command-line tools accept PBM input, enabling complex image manipulation pipelines through Unix pipes. PBM remains used in computer science education, OCR preprocessing, and any context where a dead-simple monochrome image representation is needed.
