Chkdvifont is a utility to check DVI and other T E X font-related formats (such as TFM, VF, GF and PK) and print information of those fonts. There are 3 modes;

Option -d: force DVI mode

Option -t: force TFM/OFM mode

Option -p: force other FONT mode

By default, the mode is guessed from the file extension.

(1) If you want to know what font is used in sample.dvi,

   $ chkdvifont sample.dvi
   dvi file name                   = sample.dvi
   comment                         = TeX output 2007.11.24:0632
   factor converting to 10^{-5}m   = 25400000/473628672
   magnification                   = 1000
   maximum width                   = 26083328 scaled points = 398 points
   maximum height+depth            = 11099063 scaled points = 169 points
   maximum stack depth             = 4
   number of pages                 = 13
   page size                       = 14.0 cm x  6.0 cm
   page size magnificated          = 14.0 cm x  6.0 cm

   Font 14
       checksum                    = 44D3ED74
       design size                 =  1132462 scaled points = 17 points
       space size                  =  1630536 scaled points = 24 points
       magnification               = +magstep2
       font name                   = cmr17

   Font 7
       checksum                    = 4BF16079
       design size                 =   655360 scaled points = 10 points
       space size                  =   655360 scaled points = 10 points
       font name                   = cmr10

(2) If you want to know the brief summary of jis.tfm,

   $ chkdvifont jis.tfm
   "jis" is a jfm file :  0  ->   5
   checksum                = 00000000
   design size             = 10485760 2^{-20} points = 10 points

(3) If you want to know what font is referred to by jis.vf,

   $ chkdvifont jis.vf
   "jis.vf" is in VF format
   checksum                = 00000000
   design size             = 10485760 2^{-20} points = 10 points

   Mapped Font 1
           font dsize      = 10485760 2^{-20} points = 10 points
           font at         =  0.962216
           font name       = rml

Listing the fonts used in a DVI file (as shown in the first example) is almost equivalent to dvifontlist in TeX-Guy package <http://www-masu.ist.osaka-u.ac.jp/%7Ekakugawa/TeX-Guy/> and a script dviinfox <https://ctan.org/pkg/dviinfox>. I don't know any alternatives for obtaining information about TFM, OFM, VF and other font formats.

The program chkdvifont (original name "chkfont") is derived from the DVIOUT package (DVI previewer for Windows) by Toshio OSHIMA ("SHIMA"), Yoshiki OTOBE, and Kazunori ASAYAMA. Current version is maintained by Japanese T E X Development Community <https://texjp.org>.
