NAME
psi - postscript interpreter
SYNOPSIS
psi [ option ... ] [ file ]
DESCRIPTION
Psi reads Postscript input from file or from standard input and simu-
lates the resulting pages in a mux(9.1) layer. The program remains in
the layer at exit; further invocations of psi in that layer avoid down-
load time.
The options are
-pn Display page n, where n is determined from the %%Page comments
in the file. If these are not present, page selection will not
work.
-R Pages in the file are in reverse order. This flag must be used
on such files for the -p option to work.
-r Display the image at full scale, with the bottom left corner po-
sitioned at the bottom left corner of the window. (By default,
the image is scaled to fit the window, maintaining the aspect
ratio of a printer.)
-a x y
Display the image at full scale with position x,y of the image
placed at the bottom left corner of the window.
Psi works on either a Teletype 5620, 630 or 730 terminal as determined
by the environment variable TERM.
Fonts are implemented with size-24 bitmap fonts. Those available are
Symbol, Courier, Times-Roman, Times-Italic, Times-Bold, Times-
BoldItalic, Helvetica, Helvetica-Oblique, Helvetica-Bold, Helvetica-
BoldOblique. Fonts Courier-Bold, Courier-Oblique, and Courier-
BoldOblique are mapped to Courier. Other postscript fonts, including
type1, may be used if they are supplied before they're referenced.
When the `cherries' icon is displayed, use mouse button 3 to move for-
ward (more), to a particular page (page), or quit (done). Button 2 ex-
its the program completely.
EXAMPLES
troff -ms memo | lp -dstdout -H | psi
troff -ms memo | dpost | psi
Two equivalent ways to format a memo, convert it to PostScript,
and display it.
For best results with TeX documents, use dvips with the -Tjerq, -Tgnot,
or -D 100 option to get fonts of the proper resolution and run psi with
the -r or -a flag to prevent psi from scaling.

DIAGNOSTICS
A `dead mouse' icon signals an error; error comments are placed on file
Symbols that lack bitmaps are replaced by `?' and an error is re-
ported.
BUGS
A psi layer imitates not mux. Among other difficulties, it will not be
reusable if downloaded across the network.
Unimplemented PostScript features are rotated images and half tone
screens. Imagemasks may only be rotated by multiples of 90 degrees,
not by arbitrary angles.
Skipping pages may cause operators to be undefined.
