NAME

psi − postscript interpreter

SYNOPSIS

­psi [ ­option ...  ] [ ­file ]

DESCRIPTION

­Psi reads postscript input from ­file or from standard input and simulates the resulting pages in an 8½(1) window. The options are

-pn Display page ­n. 

­-r Display the image at full scale, with the bottom left corner positioned 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. 

Fonts are implemented with size-24 bitmap fonts.  Available fonts are Symbol, Times-Roman, Times-Italic, Times-Bold, Helvetica, Helvetica-Oblique, Helvetica-Bold. 

When the ‘cherries’ icon is displayed, use mouse button 3 to move forward (more) or quit (done).  Button 2 exits the program completely. 

EXAMPLE

troff -ms memo | lp -dstdout -H | psi

Format a memo, convert it to postscript, and display it. 

FILES

­psi.err error messages

DIAGNOSTICS

Error comments are placed on file psi.err. 

Symbols that lack bitmaps are replaced by ‘?’ and an error is reported. 

BUGS

Unimplemented postscript features are rotated images or imagemasks, half tone screens, multiple path clipping, and charpath.
