NAME

tc − photoypesetter simulator

SYNOPSIS

tc [ −t ] [ −s N ] [ −p L ] [ file ]

DESCRIPTION

Tc interprets its input (standard input default) as device codes for a Graphic Systems phototypesetter (cat).  The standard output of tc is intended for a Tektronix 4015 (a 4014 terminal with ASCII and APL character sets).  The sixteen typesetter sizes are mapped into the 4014’s four sizes; the entire TROFF character set is drawn using the 4014’s character generator, using overstruck combinations where necessary.  Typical usage:

troff −t file | tc

At the end of each page tc waits for a newline (empty line) from the keyboard before continuing on to the next page.  In this wait state, the command e will suppress the screen erase before the next page; s N will cause the next N pages to be skipped; and ! line will send line to the shell. 

The command line options are:

−t Don’t wait between pages; for directing output into a file. 

−sN Skip the first N pages. 

−pL Set page length to L.  L may include the scale factors p (points), i (inches), c (centimeters), and P (picas); default is picas. 

′−l w′ Multiply the default aspect ratio, 1.5, of a displayed page by l/w.

BUGS

Font distinctions are lost. 
tc’s character set is limited to ASCII in just one size.
The aspect ratio option is unbelievable.
