XIFF (eXtended Image File Format), also known as XIF (eXtended Image Format), is a raster graphics format associated with ScanSoft corporation. It is a compound image format, similar in concept to Mixed Raster Content or JPM.
We haven't located any details about XIFF format, except that it is an extension of TIFF. Some sources say it is proprietary, though the MIME type registration indicates that there was a specification at the (long dead) URL http://www.xerox.com/xis/xiff/.
ScanSoft has a long and complicated history. It was once a part of Xerox, and is currently (since 2005) a part of Nuance Communications.
