About formats

WMF (Windows Metafile) is a vector graphics format created by Microsoft, introduced with Windows 3.0 in May 1990 as the platform's native format for recording and replaying graphical operations. A WMF file captures a sequence of GDI (Graphics Device Interface) drawing commands — lines, rectangles, ellipses, polygons, text, and bitmap blits — in the order they were issued, serializing screen or printer output into a replayable file. The format uses a 16-bit coordinate space and organizes records as a linear stream of function calls with their parameters, preceded by a header specifying the bounding rectangle and resolution. WMF became deeply integrated into the Windows ecosystem as the default format for clip art collections, Office document graphics, and clipboard vector interchange during the 1990s — Microsoft Office shipped with thousands of WMF clip art images that defined a visual era of desktop publishing. One advantage is pervasive compatibility: virtually every Windows application from the past three decades can render WMF content, making it one of the most widely supported vector formats in existence. The lightweight recording model is another strength — WMF files are compact and render quickly because they replay native system drawing calls rather than interpreting a complex graphics language. While 16-bit limitations and lack of transparency and Bezier curves led Microsoft to develop EMF as a 32-bit replacement, WMF files remain ubiquitous in legacy documents and across current Windows software.

VIFF (Visualization Image File Format) is a scientific image format developed by Khoral Research (originally at the University of New Mexico), first appearing around 1990 with the Khoros visual programming environment for image processing and data visualization. VIFF files use a 1024-byte header followed by optional color map data, and the image data itself, with the header containing detailed specifications: data storage type (bit, byte, short, integer, float, double, complex), data encoding (none, CCITT Group 3/4), color space model (none, generic, RGB, HSI, CMYK, and others), and support for multi-band (multi-channel) images with arbitrary numbers of bands. The format accommodates one-dimensional signals, two-dimensional images, three-dimensional volumes, and location data (sparse pixel coordinates), making it versatile beyond simple image storage. VIFF was designed for the Khoros/VisiQuest visual dataflow programming environment, where users constructed image processing pipelines by connecting processing nodes in a graphical canvas — an approach that influenced later systems like AVS, MATLAB Simulink, and LabVIEW. One advantage is scientific data fidelity: VIFF supports the full range of numeric types used in scientific computing (including complex numbers and double-precision floats), stores multi-band datasets natively, and carries calibration metadata — making it suitable for remote sensing, medical imaging, and spectral analysis applications where generic image formats lose information. The format's connection to the Khoros visual programming paradigm provides another notable dimension — VIFF was the standard I/O format for one of the most influential early visual programming environments for scientific image analysis. VIFF files can be read by ImageMagick and legacy Khoros/VisiQuest installations.
