DESCRIPTION

16       Chkdvifont is a utility to check DVI and other TeX font-related formats
17       (such as TFM, VF, GF and PK) and  print  information  of  those  fonts.
18       There are 3 modes;
19
20       Option -d: force DVI mode
21
22       Option -t: force TFM/OFM mode
23
24       Option -p: force other FONT mode
25
26       By default, the mode is guessed from the file extension.

EXAMPLE

29       (1) If you want to know what font is used in sample.dvi,
30
31                $ chkdvifont sample.dvi
32                dvi file name                   = sample.dvi
33                comment                         = TeX output 2007.11.24:0632
34                factor converting to 10^{-5}m   = 25400000/473628672
35                magnification                   = 1000
36                maximum width                   = 26083328 scaled points = 398
37            points
38                maximum height+depth            = 11099063 scaled points = 169
39            points
40                maximum stack depth             = 4
41                number of pages                 = 13
42                page size                       = 14.0 cm x  6.0 cm
43                page size magnificated          = 14.0 cm x  6.0 cm
44
45                Font 14
46                    checksum                    = 44D3ED74
47                    design  size                 =  1132462 scaled points = 17
48            points
49                    space size                  =  1630536 scaled points =  24
50            points
51                    magnification               = +magstep2
52                    font name                   = cmr17
53
54                Font 7
55                    checksum                    = 4BF16079
56                    design  size                 =   655360 scaled points = 10
57            points
58                    space size                  =   655360 scaled points =  10
59            points
60                    font name                   = cmr10
61
62
63       (2) If you want to know the brief summary of jis.tfm,
64
65                $ chkdvifont jis.tfm
66                "jis" is a jfm file :  0  ->   5
67                checksum                = 00000000
68                design size             = 10485760 2^{-20} points = 10 points
69
70
71       (3) If you want to know what font is referred to by jis.vf,
72
73                $ chkdvifont jis.vf
74                "jis.vf" is in VF format
75                checksum                = 00000000
76                design size             = 10485760 2^{-20} points = 10 points
77
78                Mapped Font 1
79                        font dsize      = 10485760 2^{-20} points = 10 points
80                        font at         =  0.962216
81                        font name       = rml
82
83
84       Listing the fonts used in a DVI file (as shown in the first example) is
85       almost  equivalent  to  dvifontlist  in  TeX-Guy  package  <http://www-
86       masu.ist.osaka-u.ac.jp/%7Ekakugawa/TeX-Guy/>   and  a  script  dviinfox
87       <https://ctan.org/pkg/dviinfox>.  I don't know any alternatives for ob‐
88       taining information about TFM, OFM, VF and other font formats.
