NAME

addftinfo - add information to troff font files for use with groff

SYNOPSIS

addftinfo [-asc-height n] [-body-depth n] [-body-height n] [-cap-height n] [-comma-depth n] [-desc-depth n] [-fig-height n] [-x-height n] res unitwidth font
addftinfo --help
addftinfo -v
addftinfo --version

DESCRIPTION

addftinfo reads a troff font file and adds some additional font-metric information that is used by the groff system. The font file with the information added is written on the standard output. The information added is guessed using some parametric information about the font and assumptions about the traditional troff names for characters. The main information added is the heights and depths of characters. The res and unitwidth arguments should be the same as the corresponding parameters in the DESC file; font is the name of the file describing the font; if font ends with I the font will be assumed to be italic.

OPTIONS

-v prints the version number.

All other options change one of the parameters that are used to derive the heights and depths. Like the existing quantities in the font file, each value is in inches/res for a font whose point size is unitwidth. param-option must be one of:

-x-height
The height of lowercase letters without ascenders such as x.
-fig-height
The height of figures (digits).
-asc-height
The height of characters with ascenders, such as b, d or l.
-body-height
The height of characters such as parentheses.
-cap-height
The height of uppercase letters such as A.
-comma-depth
The depth of a comma.
-desc-depth
The depth of characters with descenders, such as p, q, or y.
-body-depth
The depth of characters such as parentheses.

addftinfo makes no attempt to use the specified parameters to guess the unspecified parameters. If a parameter is not specified the default will be used. The defaults are chosen to have the reasonable values for a Times font.
