ps2fax - image POSTSCRIPT for facsimile transmission by

_p_s_2_f_a_x takes POSTSCRIPT input and generates a TIFF Class F
image file suitable for facsimile transmission. It is
usually invoked by the _H_y_l_a_F_A_X scheduler process,
_f_a_x_q(${MANNUM1_8}). On Silicon Graphics' IRIX systems,
this application is based on Adobe's Display POSTSCRIPT
software. On other machines POSTSCRIPT imaging is typi
cally done using the freely available _G_h_o_s_t_s_c_r_i_p_t soft
ware.
_p_s_2_f_a_x is actually a link (symbolic or otherwise) to the
script appropriate for the POSTSCRIPT imaging tool. The
link is setup when the _f_a_x_s_e_t_u_p(${MANNUM1_8}) script is
run to configure a _H_y_l_a_F_A_X server machine for use.
Input files containing POSTSCRIPT may be specified on the
command line. If none are given, then _p_s_2_f_a_x will read
from standard input.
By default, _p_s_2_f_a_x 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). Hori
zontal resolution is always 204 dpi. Command line options
may be used to select alternate vertical resolution and
page dimensions.
If no filename is given, _p_s_2_f_a_x writes its output to a
file named ppss..ffaaxx; the --oo 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 bound
aries. If the --22 option is specified, output is encoded
with the optional Group 3 2D-encoding scheme (EOL codes
are still padded to byte boundaries).
Note that bbiinn//ppss22ffaaxx is usually just a link to a shell
script that invokes the appropriate POSTSCRIPT RIP to do
the work.

The following operations are recognized:
--11 Write Group 3 1D-encoded data to the output
file.
--22 Write Group 3 2D-encoded data to the output
file.
--mm _p_a_g_e_s Set the maximum number of pages that are permit
ted in the output file. If more pages are pre
sent in the input document then abort process
ing.
--oo _f_i_l_e Write output to the specified _f_i_l_e instead of
the default ppss..ffaaxx filename.
--ww _w_i_d_t_h Set the output page _w_i_d_t_h, in pixels. By
default, pages are 1728 pixels wide.
--ll _l_e_n_g_t_h Set the output page _l_e_n_g_t_h in millimeters. By
default, pages are 297 millimeters long.
--rr _v_r_e_s Set the vertical resolution, in lines/inch, at
which to image the POSTSCRIPT.

Before user-supplied POSTSCRIPT is passed to the
POSTSCRIPT interpreter, a limited number of operators are
defined. These operators are operators commonly found in
a LaserWriter printer and (sometimes) generated by Macin
tosh-based applications.
The default Display POSTSCRIPT-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 uncer
tain; consult the Ghostscript documentation for informa
tion on what fonts are available.

Output from the Display POSTSCRIPT version of this command
is encoded according to the Display POSTSCRIPT binary
encoding protocol.
No prebuilt bitmap fonts are currently available for the
DPS-based imager; this would greatly improve legibility at
low resolutions, as the rendering of outline fonts at 98
lpi is particularly poor.
Both DPS- and Ghostscript-based versions of this program
fail to exit with non-zero status when an invalid
POSTSCRIPT document is processed; this makes it problem
atic for the _H_y_l_a_F_A_X queue manager to determine when a
problem arises when preparing a job for transmission.
