📋 SYNOPSIS

dvitype dvi_name[.dvi]

📖 DESCRIPTION

This manual page is not meant to be exhaustive. The complete documentation for this version of TeX can be found in the info file or manual Web2C: A TeX implementation.

The dvitype program translates a DVI (DeVice Independent) file output by (for example) tex(1) or gftodvi(1), to a file that humans can read. It also serves as a DVI file-validating program (i.e., if dvitype can read it, it's correct) and as an example of a DVI-reading program for future device drivers.

The output file can include all commands, just the important ones, or none at all (in which case only errors are reported). A subinterval of pages may be selected for transliteration; the magnification and resolution of the ``output device'' may be changed; and so on. All options are specified with an on-line dialog.

The .dvi extension is supplied if omitted from dvi_name. The output goes to stdout.

⚙️ OPTIONS

🖥️ -dpi=REAL

Set resolution to REAL pixels per inch; default 300.0.

🔍 -magnification=NUMBER

Override existing magnification with NUMBER.

📄 -max-pages=NUMBER

Process NUMBER pages; default one million.

🔊 -output-level=NUMBER

Verbosity level, from 0 to 4; default 4.

📌 -page-start=PAGE-SPEC

Start at PAGE-SPEC, for example `2' or `5.*.-2'.

🔣 -show-opcodes

Show numeric opcodes (in decimal).

🌍 ENVIRONMENT

The environment variable TEXFONTS is used to search for the TFM files used in the DVI file. See tex(1) for the details of the searching. If TEXFONTS is not set, it uses the system default.
