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/.

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.

Contents

Format details

XIFF is an extension of TIFF. There is extension data starting at offset 8, which is not referenced by any TIFF tag.

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.

File Identification

Evidence suggests there is an ASCII signature at offset 8. The signature can be either "XEROX DIFF", or " eXtended "[5] (with the leading and trailing space).

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.
