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.

PFM (Portable Float Map) is a floating-point raster image format devised by Paul Debevec around 2001, designed to store high-dynamic-range image data with the simplicity of the Netpbm family of formats. PFM extends the PBM/PGM/PPM philosophy — minimal header, raw data, no compression — to 32-bit IEEE floating-point samples, providing direct access to HDR pixel values without the encoding overhead of formats like OpenEXR or the limited range of Radiance HDR's RGBE encoding. The file structure is deliberately minimal: a two-character magic number ('Pf' for grayscale, 'PF' for color), width and height on the next line, a scale/endianness indicator (negative for little-endian, positive for big-endian, with magnitude indicating scale factor), and then the raw 32-bit float data for each pixel. PFM files store one float per pixel for grayscale or three floats (RGB) per pixel for color, with no compression, alpha channel, or metadata support. The format emerged from the HDR imaging research community where Debevec's work on image-based lighting and light stage capture required a simple, unambiguous way to store linear floating-point radiance values that could be easily exchanged between research tools. One advantage is absolute simplicity for HDR data: PFM can be read and written in a few lines of code in any language that supports IEEE floats, with no library dependencies — ideal for research prototyping and quick data exchange between custom tools. The format's widespread adoption in the computer vision and computational photography research community is another practical strength — optical flow benchmarks (Middlebury), depth estimation datasets, and radiance field captures commonly use PFM. The format is supported by ImageMagick, OpenCV, HDR Shop, and Luminance HDR.
