.lg 0
.SH SYNOPSIS
.B psifile
[
.I option ...
] [
.I file
]
.br
.B mhssend
.I phone_number
.I file
.SH DESCRIPTION
.I Psifile
reads Postscript input from
.I file
or from standard input
and produces a file containing an image of the page.
The format of the output file is specified by the following options:
.TF /make/it
.TP
.B -fax
runs at 200 dpi and produces g31 fax in the multipage fax format called
.BR mhs ,
putting its output in file
.B fax\fI$$\fP.mhs
by default. If a phone number is supplied,
the output file is pushed to
.B /tmp
on fama
and
.B mhssend
is run to send the fax.
.TP
.BI -P " phone_no"
specifies the destination phone number for
.BR -fax .
.TP
.B -g4
runs at 300 dpi and produces a fax g4 file called
.B psi.out.g4
by default that
can be displayed on the gnots with
.IR rbits .
.TP
.B -bm
produces
.IR bitfile (9.5)
output in file
.B psi.out
by default.
.I -bm
is useful for debugging postscript programs because
it has better diagnostics than the printers.
.PP
Other options are
.TF /this/is
.TP
.B -s
assumes the file is in
.B mhs
format and sends it to the phone number provided with
.B -P
above.
.TP
.BI -o " name"
use
.I name
as the basename of the output file.
.TP
.BI -p " page"
only output postscript page number
.I page
as determined by
.B %%Page
comments in the file.
.sp
.PP

.sp
.PP
For best results with TeX documents, run
.B dvips
with the
.B -Tfax
or
.B "-D 200"
option to get fonts of the proper resolution.
.SH EXAMPLES
.TP
.L
troff -ms memo | lp -dstdout -H | psifile -fax -P 4223

and half tone screens.
Imagemasks may only be rotated by multiples of 90 degrees,
not by arbitrary angles.
