SYNOPSIS
/var/spool/hylafax/bin/pdf2fax
[

DESCRIPTION
pdf2fax
takes Portable Document Format (PDF) input and generates a
TIFF
Class F image file suitable for facsimile transmission.
It is usually invoked by the HylaFAX scheduler process,
faxq(8C).
PDF imaging is typically done using the
freely available
Ghostscript
software.
pdf2fax
is actually a link (symbolic or otherwise) to the script
appropriate for the PDF imaging tool.
The link is setup when the
faxsetup(8C)
script is run to configure a HylaFAX server machine for use.
Input files containing PDF may be specified on the
command line.
If none are given, then
pdf2fax
will read from standard input.
By default,
pdf2fax
will generate a 98 line/inch output document whose
page width is 1728 pixels and page length is 297 mm
(a standard A4 page at low resolution).
Horizontal resolution is always 204 dpi.
Command line options may be used to select alternate
vertical resolution and page dimensions.
If no filename is given,
pdf2fax
writes its output to a file named
pdf.fax;
the
-o
option can be used to specify an alternate filename.
By default, output is compressed using the standard
Group 3 1D-encoding scheme, with
EOL
codes padded to byte boundaries.
If the
-2
option is specified, output is encoded with the optional
Group 3 2D-encoding scheme (EOL
codes are still padded to byte boundaries).
Note that
bin/pdf2fax
is usually just a link to a shell script that invokes the
appropriate PDF
RIP
to do the work.
OPTIONS
The following operations are recognized:
- -1
-
Write Group 3 1D-encoded data to the output file.
- -2
-
Write Group 3 2D-encoded data to the output file.
- -m pages
-
Set the maximum number of pages that are permitted in the
output file.
If more pages are present in the input document then
abort processing.
- -o file
-
Write output to the specified
file
instead of the default
pdf.fax
filename.
- -w width
-
Set the output page
width,
in pixels.
By default, pages are 1728 pixels wide.
- -l length
-
Set the output page
length
in millimeters.
By default, pages are 297 millimeters long.
- -r vres
-
Set the vertical resolution,
in lines/inch, at which to image the PDF.
RUNTIME ENVIRONMENT
Before user-supplied PDF is passed
to the PDF interpreter, a limited number of
operators are defined.
These operators are operators commonly found in a
LaserWriter printer and (sometimes) generated by Macintosh-based
applications.
The default Display PDF-based execution
environment includes support for the following fonts:
AvantGarde-Book Helvetica-Bold Palatino-BoldItalic
AvantGarde-BookOblique Helvetica-BoldOblique Palatino-Italic
AvantGarde-Demi Helvetica-Narrow Palatino-Roman
AvantGarde-DemiOblique Helvetica-Narrow-Bold StoneSerif
Bookman-Demi Helvetica-Narrow-BoldOblique Symbol
Bookman-DemiItalic Helvetica-Narrow-Oblique Tekton
Bookman-Light Helvetica-Oblique Times-Bold
Bookman-LightItalic Lithos-Bold Times-BoldItalic
Courier NewCenturySchlbk-Bold Times-Italic
Courier-Bold NewCenturySchlbk-BoldItalic Times-Roman
Courier-BoldOblique NewCenturySchlbk-Italic ZapfChancery-MediumItalic
Courier-Oblique NewCenturySchlbk-Roman ZapfDingbats
Helvetica Palatino-Bold
Note that this is the same set of fonts supported by the
DPS
extension to the X server.
The default Ghostscript-based environment is more uncertain;
consult the Ghostscript documentation for information on
what fonts are available.
BUGS
Output from the Display PDF version of this command
is encoded according to the Display PDF binary encoding
protocol.
Ghostscript-based versions of this program fail to exit with
non-zero status when an invalid PDF document is processed;
this makes it problematic for the HylaFAX queue manager to
determine when a problem arises when preparing a job for
transmission.
