About formats

VIPS is the native file format of the libvips image processing library, originally developed by John Cupitt and Kirk Martinez at the National Gallery in London during the VASARI project (1989-1993) for high-resolution digitization and analysis of paintings. The VIPS format stores large images in a simple, memory-mappable layout: a header containing image dimensions, number of bands (channels), data type (8/16/32-bit integer, float, double, complex), color interpretation, resolution, and offset metadata, followed by the raw pixel data in band-interleaved format. This straightforward layout allows the operating system's virtual memory manager to map the file directly into address space, enabling libvips to process images much larger than available RAM by paging portions in and out as needed — a technique called demand-driven evaluation. VIPS files support images with any number of bands at any of the supported numeric types, accommodating everything from standard RGB photographs to hyperspectral datasets with hundreds of bands. One advantage is large-image performance: libvips's architecture processes images in small tiles evaluated on demand, meaning a 100,000 x 100,000 pixel image can be cropped, resized, sharpened, and saved without loading the entire image into memory — a capability that makes VIPS the engine behind image processing services handling millions of web images. The format's scientific heritage is another strength — the VASARI project required analyzing paintings at ultra-high resolution with multispectral imaging, and the VIPS format's support for arbitrary band counts and floating-point precision reflects these computational imaging origins. VIPS files are primarily used with the libvips library (available for C, Python, Ruby, and other languages) and can be converted to other formats via vips command-line tools or ImageMagick.

FAX is a generic image file extension associated with facsimile transmission formats standardized by the ITU-T (formerly CCITT), with the underlying Group 3 compression standard ratified in 1980. FAX files typically contain monochrome (1-bit, black and white) image data compressed using the Modified Huffman (MH) encoding defined in ITU-T Recommendation T.4, which assigns variable-length codes to run lengths of consecutive white or black pixels along each scanline. The standard resolution for Group 3 fax is 204x98 dpi (normal mode) or 204x196 dpi (fine mode), reflecting the capabilities of thermal and laser fax machines of the era. FAX files encountered digitally are often raw Group 3 encoded bitstreams or TIFF wrappers with CCITT Group 3 compression (TIFF compression tag 3). The Group 3 encoding scheme is highly efficient for typical business documents — pages with mostly white space and black text — achieving compression ratios of 10:1 to 20:1 compared to uncompressed bitmaps. One advantage is universal fax system compatibility: Group 3 encoding is the mandatory baseline for all fax machines worldwide, meaning FAX files contain data in exactly the format transmitted over telephone lines, preserving the original fax data without transcoding losses. The format's role in business communications history provides another dimension — billions of fax transmissions using this encoding moved legal documents, medical records, and business correspondence for decades, and archived FAX files represent an important documentary record. FAX images can be viewed and converted using LibreOffice, ImageMagick, GIMP, and standard document management systems.
