61 this file should consist of a sequence of lines of the form: 62 .IP 63 .I 64 n c1 c2 \fR.\|.\|. 65 .LP 66 where 67 .I n 68 is a decimal integer giving the position of the character in the font, 69 and 70 .IR c1 , 71 .IR c2 ,.\|.\|. 72 are the groff names of the character. 73 If a character has no groff names but exists in the tfm file, 74 then it will be put in the groff font file as an unnamed character. 75 .I font 76 is the name of the groff font file. 77 The groff font file is written to 78 .IR font . 79 .LP 80 The 81 .B \-s 82 option should be given if the font is special 83 (a font is 84 .I special 85 if 86 .B troff 87 should search it whenever 88 a character is not found in the current font.) 89 If the font is special, 90 it should be listed in the 91 .B fonts 92 command in the DESC file; 93 if it is not special, there is no need to list it, since 94 .B troff 95 can automatically mount it when it's first used. 96 .LP 97 To do a good job of math typesetting, groff requires 98 font metric information not present in the tfm file. 99 The reason for this is that \*(tx has separate math italic fonts 100 whereas groff uses normal italic fonts for math. 101 The additional information required by groff is given by the 102 two arguments to the 103 .B math_fit 104 macro in the Metafont programs for the Computer Modern fonts. 105 In a text font (a font for which 106 .B math_fitting 107 is false), Metafont normally ignores these two arguments. 108 Metafont can be made to put this information in the gf file 109 by loading the following definition after 110 .B cmbase 111 when creating 112 .BR cm.base : 113 .IP 114 .nf 115 .ft B 116 def ignore_math_fit(expr left_adjustment,right_adjustment) = 117 special "adjustment"; 118 numspecial left_adjustment*16/designsize; 119 numspecial right_adjustment*16/designsize; 120 enddef; 121 .fi 122 .ft R 123 .LP 124 For the EC font family, load the following definition after 125 .B exbase 126 (it is probably easiest to patch 127 .B exbase.mf 128 locally): 129 .IP 130 .nf 131 .ft B 132 def ignore_math_fit(expr left_adjustment,right_adjustment) = 133 ori_special "adjustment";
