13 pdf2fax takes Portable Document Format (PDF) input and generates a TIFF
14 Class F image file suitable for facsimile transmission. It is usually
15 invoked by the HylaFAX scheduler process, faxq(8C). PDF imaging is
16 typically done using the freely available Ghostscript software.
17 pdf2fax is actually a link (symbolic or otherwise) to the script appro‐
19 priate for the PDF imaging tool. The link is setup when the
20 faxsetup(8C) script is run to configure a HylaFAX server machine for
21 use.
22 Input files containing PDF may be specified on the command line. If
24 none are given, then pdf2fax will read from standard input.
25 By default, pdf2fax will generate a 98 line/inch output document whose
27 page width is 1728 pixels and page length is 297 mm (a standard A4 page
28 at low resolution). Horizontal resolution is always 204 dpi. Command
29 line options may be used to select alternate vertical resolution and
30 page dimensions.
31 If no filename is given, pdf2fax writes its output to a file named
33 pdf.fax; the -o option can be used to specify an alternate filename.
34 By default, output is compressed using the standard Group 3 1D-encoding
36 scheme, with EOL codes padded to byte boundaries. If the -2 option is
37 specified, output is encoded with the optional Group 3 2D-encoding
38 scheme (EOL codes are still padded to byte boundaries).
39 This script can modify outgoing facsimile, such as watermarking, To do
41 this create a shell script etc/FaxModify in the spooling area that
42 alters the document.
43 Note that bin/pdf2fax is usually just a link to a shell script that
45 invokes the appropriate PDF RIP to do the work.
46
48 The following operations are recognized:
49 -1 Write Group 3 1D-encoded data to the output file.
51 -2 Write Group 3 2D-encoded data to the output file.
53 -3 Write Group 4 MMR-encoded data to the output file.
55 -color Write color data to an output file (possibly a separate file
57 if Group 3 or Group 4 data is also being output).
58 -i jobid How the server references the associated Job ID number
60 -m pages Set the maximum number of pages that are permitted in the
62 output file. If more pages are present in the input document
63 then abort processing.
64 -o file Write output to the specified file instead of the default
66 pdf.fax filename.
67 -w width Set the output page width, in pixels. By default, pages are
69 1728 pixels wide.
70 -l length Set the output page length in millimeters. By default, pages
72 are 297 millimeters long.
73 -r vres Set the vertical resolution, in lines/inch, at which to image
75 the PDF.
76
78 Before user-supplied PDF is passed to the PDF interpreter, a limited
79 number of operators are defined. These operators are operators com‐
80 monly found in a LaserWriter printer and (sometimes) generated by Mac‐
81 intosh-based applications.
82 The default Display PDF-based execution environment includes support
84 for the following fonts:
85 AvantGarde-Book Helvetica-Bold Palatino-BoldItalic
86 AvantGarde-BookOblique Helvetica-BoldOblique Palatino-Italic
87 AvantGarde-Demi Helvetica-Narrow Palatino-Roman
88 AvantGarde-DemiOblique Helvetica-Narrow-Bold StoneSerif
89 Bookman-Demi Helvetica-Narrow-BoldOblique Symbol
90 Bookman-DemiItalic Helvetica-Narrow-Oblique Tekton
91 Bookman-Light Helvetica-Oblique Times-Bold
92 Bookman-LightItalic Lithos-Bold Times-BoldItalic
93 Courier NewCenturySchlbk-Bold Times-Italic
94 Courier-Bold NewCenturySchlbk-BoldItalic Times-Roman
95 Courier-BoldOblique NewCenturySchlbk-Italic ZapfChancery-MediumItalic
96 Courier-Oblique NewCenturySchlbk-Roman ZapfDingbats
97 Helvetica Palatino-Bold
98 Note that this is the same set of fonts supported by the DPS extension
99 to the X server.
100 The default Ghostscript-based environment is more uncertain; consult
102 the Ghostscript documentation for information on what fonts are avail‐
103 able.
104
106 Output from the Display PDF version of this command is encoded accord‐
107 ing to the Display PDF binary encoding protocol.
108 Ghostscript-based versions of this program fail to exit with non-zero
110 status when an invalid PDF document is processed; this makes it prob‐
111 lematic for the HylaFAX queue manager to determine when a problem
112 arises when preparing a job for transmission.
