Recommendation:
 
  The IESG recommends that the Internet Draft "A File Format for the
  Exchange of Images in the Internet" <draft-ietf-netfax-netimage-03> be
  published as a Proposed Standard.  This document is the product of the
  Network Fax Working Group of the IETF.
 
Abstract:

  This document defines a file format for the exchange of lossless black
  and white images, such as FAX, within the Internet.

Technical Summary:

  The protocol requires that:

  o The file format should be TIFF-B with multi-page files
    supported.  Images should be encoded as one TIFF strip
    per page.

  o 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".

  o 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).
