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. McIntyre, et. al.
