🚀 Quick Reference

Use Case	Command	Description
🔍 Check DVI fonts	chkdvifont sample.dvi	List all fonts used in a DVI file
📊 Get TFM info	chkdvifont jis.tfm	Show checksum and design size of a TFM font
🧩 Get VF mappings	chkdvifont jis.vf	Show mapped fonts and design sizes in a VF
🖥️ Force DVI mode	chkdvifont -d file	Override extension detection to DVI mode
📏 Force TFM mode	chkdvifont -t file	Override extension detection to TFM mode
🔤 Force FONT mode	chkdvifont -p file	Override extension detection to FONT mode

⚙️ 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.
