NAME
    hpftodit - create font description files for use with groff -Tlj4

SYNOPSIS
    hpftodit [ -sv ] [ -in ] tfm_file map_file font

    It is possible  to have whitespace between the -i command line option
    and its parameter.

DESCRIPTION
    hpftodit creates a font file for use with groff -Tlj4 from an HP tagged
    font metric file. tfm_file is the name of the tagged font metric file
    for the font. map_file is a file giving the groff names for characters
    in the font; this file should consist of a sequence of lines of the
    form:

    n c1 c2 ...

    where n is a decimal integer giving the MSL number of the character,
    and c1, c2,... are the groff names of the character. font is the name
    of the groff font file. The groff font file is written to font.

    The -s option should be given if the font is special (a font is special
    if troff should search it whenever a character is not found in the cur-
    rent font.) If the font is special, it should be listed in the  fonts
    command in the  DESC file; if it is not special, there is no need to
    list it, since troff can automatically mount it when it's first used.

    If the -i option is used, hpftodit will automatically generate an
    italic correction, a left italic correction and a subscript correction
    for each character (the significance of these parameters  is explained
    in groff_font(5)).

OPTIONS
    -v   Print the version number.

    -s   The font  is special. The effect of this option is to add the
    special command to the font file.

    -in  Generate an italic correction for each character  so that the
    character's width plus the character's italic correction is
    equal to n design units plus the amount by which the right edge
    of the character's bounding is to the right of the character's
    origin. If this would result in a negative italic correction,
    use a zero italic correction instead.  There are 8782 design
    units per em for Intellifont fonts.

    Also generate a subscript correction equal to the product of the
    tangent of the slant of the font and four fifths of the x-height
    of the font. If this would result in a  subscript correction
    greater than the italic correction, use a subscript correction
    equal to the italic correction instead.

    Also generate a left italic correction for each character  equal
    to n design units plus the amount by which the left edge of the
    character's bounding box is to the left of the character's ori-
    gin. The left italic correction may be negative.

    This option is normally needed only with italic (or oblique)
    fonts.

FILES
    /usr/share/groff/1.18.1/font/devlj4/DESC

    /usr/share/groff/1.18.1/font/devlj4/F
    Font description file for font F.

BUGS
    This program was written without the benefit of complete, official doc-
    umentation on the tagged font metric format. It is therefore likely
    that it will fail to work on tfm files that are dissimilar to those for
    the internal fonts on the Laserjet 4, with which it was tested:

    TrueType tfm files are not supported.
