NAME
       chkdvifont - CHecK DVI/tfm/font file and report information of FONTs

SYNOPSIS
       chkdvifont [-s] [-c] [-{f|F}<font_data_file>] [-d] dvi_file_name

       chkdvifont [-s] [-c] [-{f|F}<font_data_file>] [-t] tfm_file_name

       chkdvifont [-s] [-c] [-{f|F}<font_data_file>] [-p] font_file_name

DESCRIPTION
       Chkdvifont is a utility to check DVI and other TeX 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.

EXAMPLE
       (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.
