NAME

       vwidth - make troff width table for a font

SYNOPSIS

       vwidth fontfile pointsize > ftxx.c
       cc -c ftxx.c mv ftxx.o /usr/share/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 necessary 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/share/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/share/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.
