ADDFTINFO Linux Command

What is Linux addftinfo Command?


addftinfo COMMAND:

The ADDFTINFO command adds information to troff font files for use with groff. This command reads a troff font file and adds some additional font-metric information used by the groff system and writes the updated font file on the standard output. The information added to the font file is about the parametric information and assumptions about the traditional troff names about the fonts, such as 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.


addftinfo [-v] [-param value] ... resolution unitwidth font


-v prints the version number.

All other options changes one of the parameters that is 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 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.
