<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> |
