chkdvifont - CHecK DVI/tfm/font file and tell informations of FONTs

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

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.

(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^-5m = 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 TeX Development Community https://texjp.org.
