About formats

XV is an alternate file extension for the VIFF (Visualization Image File Format) developed by Khoral Research as part of the Khoros scientific image processing environment, which originated at the University of New Mexico around 1990. The .xv extension and the .viff extension refer to the same underlying format — a container with a 1024-byte header encoding image dimensions, data type (from single-bit to double-precision float and complex numbers), color space, band count, and optional spatial location metadata, followed by color map data and pixel values. The XV extension became common on systems where Khoros was installed alongside other X Window System tools, and in some research communities .xv was preferred over .viff as a shorter alternative. Khoros itself was a pioneering visual programming system where scientists assembled image processing pipelines by wiring together processing nodes in a graphical canvas — an approach that predated and influenced similar environments in MATLAB, LabVIEW, and commercial remote sensing packages. One advantage of the VIFF/XV format is its ability to store data at scientific precision levels — floating-point and complex number pixel values preserve measurement accuracy that would be lost in photographic formats limited to 8-bit or 16-bit integers, making it valuable for spectral analysis, computational physics output, and satellite imagery. The multi-band architecture provides another strength, allowing a single file to hold dozens of spectral channels from multispectral or hyperspectral sensors without splitting data across multiple files. XV files are supported by ImageMagick and can be converted to modern image formats for visualization or publication.

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.
