NAME¶

dvitype, odvitype - translate a dvi file for humans to read

SYNOPSIS¶

dvitype dvi_file[.dvi]

DESCRIPTION¶

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-processing program for future device drivers.

The output from dvitype 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, the magnification and resolution of the ``output device'' may be changed, and so on.

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

The odvitype program does the same job for Omega/Aleph's output, modified to support their .ofm font format.

OPTIONS¶

See tex(1) for details of command-line parsing.

-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).

The standard -help and -version options are also supported.

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.
