| 4 | addftinfo \- add information to troff font files for use with groff | |
| 5 | .SH SYNOPSIS | |

| 7 | [ | |

| 12 | .I font | |
| 13 | .SH DESCRIPTION | |
| 14 | .B addftinfo | |
| 15 | reads a troff font file | |
| 16 | and adds some additional font-metric information | |
| 17 | that is used by the groff system. | |
| 18 | The font file with the information added is written on the | |
| 19 | standard output. | |
| 20 | The information added is guessed using | |
| 21 | some parametric information about the font | |
| 22 | and assumptions | |
| 23 | about the traditional troff names for characters. | |
| 24 | The main information added is the heights and depths of characters. | |
| 25 | The | |
| 26 | .I res | |
| 27 | and | |
| 28 | .I unitwidth | |
| 29 | arguments should be the same as the corresponding parameters | |
| 30 | in the DESC file; | |
| 31 | .I font | |
| 32 | is the name of the file describing the font; | |
| 33 | if | |
| 34 | .I font | |
| 35 | ends with | |
| 36 | .B I | |
| 37 | the font will be assumed to be italic. | |
| 38 | .SH OPTIONS | |
| 39 | Each of the options changes one of the parameters that is used | |
| 40 | to derive the heights and depths. | |
| 41 | Like the existing quantities in the font | |
| 42 | file, each | |
| 43 | .I value | |
| 44 | is in | |
| 45 | .RI inches/ res | |
| 46 | for a font whose point size is | |
| 47 | .IR unitwidth . | |
| 48 | .I param | |
| 49 | must be one of: | |
| 50 | .TP | |
| 51 | .B x-height | |
| 52 | The height of lowercase letters without ascenders such as x. | |
| 53 | .TP | |
| 54 | .B fig-height | |
| 55 | The height of figures (digits). | |
| 56 | .TP | |
| 57 | .B asc-height | |
| 58 | The height of characters with ascenders, such as b, d or l. | |
| 59 | .TP | |
| 60 | .B body-height | |
| 61 | The height of characters such as parentheses. | |
| 62 | .TP | |
| 63 | .B cap-height | |
| 64 | The height of uppercase letters such as A. | |
| 65 | .TP | |
| 66 | .B comma-depth | |
| 67 | The depth of a comma. | |
| 68 | .TP | |
| 69 | .B desc-depth | |
| 70 | The depth of characters with descenders, such as p,q, or y. | |
| 71 | .TP | |
| 72 | .B body-depth | |
| 73 | The depth of characters such as parentheses. | |
| 74 | .LP | |
| 75 | .B addftinfo | |
| 76 | makes no attempt to use the specified parameters to guess | |
| 77 | the unspecified parameters. | |
| 78 | If a parameter is not specified the default will be used. | |
| 79 | The defaults are chosen to have the reasonable values for | |
| 80 | a Times font. | |
