CHKDVIFONT(1)

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.
