NAME
       vwidth - make troff width table for a font

SYNOPSIS
       vwidth fontfile pointsize > ftxx.c
       cc -c ftxx.c mv ftxx.o /usr/lib/font/ftxx

DESCRIPTION
       Vwidth  translates from the width information stored in the vfont style
       format to the format expected by troff.  Troff wants an object file  in
       a.out(5)  format.  (This fact does not seem to be documented anywhere.)
       Troff should look directly in the font file but it doesn’t.

       Vwidth should be used after editing a font with fed(1).  It is not nec‐
       essary  to  use  vwidth unless you have made a change that would affect
       the width tables.  Such changes include numerically editing  the  width
       field,  adding  a new character, and moving or copying a character to a
       new position.  It is not always necessary to use vwidth if the physical
       width  of  the glyph (e.g. the number of columns in the bit matrix) has
       changed, but if it has changed much the logical width  should  probably
       be changed and vwidth run.

       Vwidth  produces  a  C  program  on  its standard output.  This program
       should be run through the C compiler and the object (that  is,  the  .o
       file)  saved.   The resulting file should be placed in /usr/lib/font in
       the file ftxx where is a one or two letter code  that  is  the  logical
       (internal  to  troff)  font name.  This name can be found by looking in
       the file /usr/lib/fontinfo/fname* where fname is the external  name  of
       the font.

BUGS
       Produces  the C file using obsolete syntax that the portable C compiler
       complains about.
