Abstract
This document describes the TIFF (Tag Image File Format)
representation of image data specified by the ITU-T Recommendations
for black-and-white and color facsimile. This file format
specification is commonly known as TIFF-FX. It formally defines
minimal, extended and lossless JBIG modes (Profiles S, F, J) for
black-and-white fax, and base JPEG, lossless JBIG and Mixed Raster
Content modes (Profiles C, L, M) for color and grayscale fax. These
modes or profiles correspond to the content of the applicable ITU-T
Recommendations. Files formatted according to this specification use
the image/tiff MIME Content Type.
