1. Abstract

This document references the Tag Image File Format (TIFF) to define

the F profile of TIFF for facsimile (TIFF-F) as a file format that

may be used for the storage and interchange of facsimile images.

2. TIFF Definition

TIFF (Tag Image File Format) Revision 6.0 is defined in detail within

[TIFF].

A brief review of concepts used in TIFF is included in this document

as background information, but the reader is directed to the original

TIFF specification [TIFF] to obtain specific technical details.

2.1 Baseline TIFF and Applications

TIFF provides a method to describe and store raster image data. A

primary goal of TIFF is to provide a rich environment within which

implementations can exchange image data. [TIFF] characterizes

Baseline TIFF as being the core of TIFF, the essentials that all

mainstream TIFF developers should support in their products.

Applications of TIFF are defined by using Baseline TIFF as a starting

point and then defining "extensions" to TIFF that are used for the

specific "application", as well as specifying any other differences

from Baseline TIFF.

3. TIFF-F Definition

3.1 Introduction

Though it has been in common usage for many years, TIFF-F has

previously never been documented in the form of a standard. An

informal TIFF-F document was originally created by a small group of

fax experts led by Joe Campbell. The existence of TIFF-F is noted in

[TIFF] but it is not defined. This document defines the F

application of [TIFF]. For ease of reference, the term TIFF-F will be

used throughout this document as a shorthand for "F Profile of TIFF

for Facsimile". TIFF-F files are intended for use with the

image/tiff MIME media content-type which includes support for the

"application" parameter (e.g., application=faxbw).
