<abstract>
<t>This document defines a standard file format for the exchange of fax-like black and white images within the Internet.  It is a product of the Network Fax Working Group of the Internet Engineering Task Force (IETF).</t>
<t>The standard is:</t>
<t>** The file format should be TIFF-B with multi-page files supported.  Images should be encoded as one TIFF strip per page.</t>
<t>** Images should be compressed using MMR when possible.  Images may also be MH or MR compressed or uncompressed.  If MH or MR compression is used, scan lines should be "byte-aligned".</t>
<t>** For maximum interoperability, image resolutions should either be 600, 400, or 300 dpi; or else be one of the standard Group 3 fax resolutions (98 or 196 dpi vertically and 204 dpi horizontally).</t>
<t>Note that this specification is self contained and an implementation should be possible without recourse to the TIFF references, and that only the specific TIFF documents cited are relevant to this specification.  Updates to the TIFF documents do not change this specification.</t>
<t>Experimentation with this file format specified here is encouraged.</t></abstract></front>
