VIFF, or Khoros Visualization image, is a raster image file format associated with the Khoros data analysis and visualization software. It is a fairly complex format, supporting a variety of image types, color spaces, compression schemes, etc.
Apparently, there are at least two Khoros formats named VIFF. Khoros 1.x's VIFF (1.0) format was called "xvimage" by Khoros 2.x, and a new "VIFF" (2.0) format was introduced.

History
Khoros was originally developed at the University of New Mexico. The first public beta release was in 1990, and the first official release was in 1991. Somehow (in 1992?) it came to be owned by a company named Khoral. In 1996, it was split into two products: Khoros Pro and Advanced Khoros. In 2004, Khoros Pro was sold to Accusoft and renamed VisiQuest.
Format
VIFF 1.0 files begin with a 1024-byte fixed header.
Identification
VIFF 1.0 files start with bytes ab 01.
Some or all VIFF 2.0 files start with 08 13 57 9a.
Software
- ImageMagick (format named "VIFF" or "XV")
- Khoros
Sample files

- input.viff (PerlMagick test file)
