'''VIFF''', or '''Khoros Visualization image''', is a raster image file format. It is a fairly complex format, supporting a variety of image types, color spaces, compression schemes, etc.

== Format ==
VIFF files begin with a 1024-byte fixed header.

== Identification ==
Files start with bytes <code>0xAB 0x01</code>.

 '''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 format (which we'll call VIFF 1.0) was called "xvimage" by Khoros 2.x, and a new "VIFF" (2.0) format was introduced.

Note that this "xvimage" format is not related to the [http://www.trilon.com/xv/ XV image viewer], and presumably is not related to the [[Wikipedia:XvImage|XvImage X Window System format]].
