53 | <p><i>Fax2tiff</i> creates a <small>TIFF</small> file | |
54 | containing <small>CCITT</small> Group 3 or Group 4 encoded | |
55 | data from one or more files containing | |
56 | ‘‘raw’’ Group 3 or Group 4 encoded | |
57 | data (typically obtained directly from a fax modem). By | |
58 | default, each row of data in the resultant | |
59 | <small>TIFF</small> file is 1-dimensionally encoded and | |
60 | padded or truncated to 1728 pixels, as needed. The resultant | |
61 | image is a set of low resolution (98 lines/inch) or medium | |
62 | resolution (196 lines/inch) pages, each of which is a single | |
63 | strip of data. The generated file conforms to the | |
64 | <small>TIFF</small> Class F ( <small>FAX</small> ) | |
65 | specification for storing facsimile data. This means, in | |
66 | particular, that each page of the data does <b>not</b> | |
67 | include the trailing <i>return to control</i> ( | |
68 | <small>RTC</small> ) code; as required for transmission by | |
69 | the <small>CCITT</small> Group 3 specifications. The old, | |
70 | ‘‘classic’’, format is created if | |
71 | the <b>−c</b> option is used. (The Class F format can | |
72 | also be requested with the <b>−f</b> option.)</p> | |
73 | <!-- INDENTATION --> | |
74 | <p>The default name of the output image is <i>fax.tif</i>; | |
75 | this can be changed with the <b>−o</b> option. Each | |
76 | input file is assumed to be a separate page of facsimile | |
77 | data from the same document. The order in which input files | |
78 | are specified on the command line is the order in which the | |
79 | resultant pages appear in the output file.</p> | |
