XIFF (eXtended Image File Format, Xerox Image File Format[1]), also known as XIF (eXtended Image Format, Xerox Image Format[2]) and also DigiPaper/XIF[3][4], and apparently also Xerox DIFF, is a raster graphics format associated with ScanSoft and Xerox. It is a compound image format, similar in concept to Mixed Raster Content or JPM.

XIFF is probably considered to be proprietary, though the MIME type registration indicates that there was a specification at the (long dead) URL http://www.xerox.com/xis/xiff/.[5]

Also used as the file format for Fax software such as the FaxWave service.[6]

ScanSoft has a long and complicated history. It was a part of Xerox around the time XIFF was developed, and since 2005 is a part of Nuance Communications.

[edit] Format details

XIFF is an extension of TIFF. There is extension data starting at offset 8, which is not referenced by any TIFF tag. Also related to the TIFF-F[7] specification.[8]

XIFF is possibly related to TIFF-FX mixed raster content subtype (See RFC 2301 & RFC 2531).

A TIFF viewer that does not support XIFF will likely either not display certain elements at all, or display them as separate pages.

[edit] File Identification

XIFF 3.0 Header begins with the standard TIFF header, at offset 8 for 10 bytes contains either "XEROX DIFF", or " eXtended " for version 2 & 3 respectively. At offset 18 there is one byte to indicate version, followed by another byte at offset 19 to indicate a revision number. See page 25 of XIFF 3.0 spec [9] and this forensic book [10]

[edit] Disambiguation

  • Not related to the XIFF instant messaging library.
  • Not related to XLIFF (XML Localisation Interchange File Format). (It's apparently a common typo to write "XIFF" instead of "XLIFF".)

See also the XIF disambiguation page.
