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 .I res and .I unitwidth arguments should be the same as the corresponding parameters in the DESC file; .I font is the name of the file describing the font; if .I font ends with .B I the font will be assumed to be italic. .SH OPTIONS Each of the options changes one of the parameters that is used to derive the heights and depths. Like the existing quantities in the font file, each .I value is in .RI inches/ res for a font whose point size is .IR unitwidth . .I param must be one of: .TP .B x-height The height of lowercase letters without ascenders such as x. .TP .B fig-height The height of figures (digits). .TP .B asc-height The height of characters with ascenders, such as b, d or l. .TP .B body-height The height of characters such as parentheses. .TP .B cap-height The height of uppercase letters such as A. .TP .B comma-depth The depth of a comma. .TP .B desc-depth The depth of characters with descenders, such as p,q, or y. .TP .B body-depth The depth of characters such as parentheses. .LP .B 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. .SH "SEE ALSO" .BR font (5) .BR groff_font (@MAN5EXT@), .BR groff (@MAN1EXT@), .BR groff_char (@MAN7EXT@)
