DT2DV(1) General Commands Manual DT2DV(1)


dt2dv - convert a DTL text representation of a TeX DVI file to a binary DVI file


dt2dv [-debug] [-group] [-si] [-so] [input-DTL-file] [output-DVI-file]

In the absence of the -si and -so options, both file arguments are required in the order input-DTL-file output-DVI-file. But also see the OPTIONS section below. No default file extensions are supplied.


dt2dv converts a text representation of a TeX DVI file, usually produced by the companion dv2dt(1) utility, back to a binary DVI file. DTL (DVI Text Language) files can be edited, with care, and then restored to DVI form for processing by any TeX DVI driver program. In DTL files, font directory names and font names are preceded by a length field, which must be updated if the names are modified.

dvitype(1) can also display a textual representation of DVI files, but in some implementations at least, it cannot be used in batch mode, and its output is not well-suited for conversion back to a DVI file.

The format of TeX DVI files is fully described in Donald E. Knuth, TeX: The Program, Addison-Wesley (1986), ISBN 0-201-13437-3, as well as in the dvitype(1) literate program source code. Brief descriptions of the DTL and DVI formats are given in dv2dt(1).


Turn on detailed debugging output.
Expect each DTL command to be in parentheses.
Read all DTL commands from standard input.
Write all DVI commands to standard output.
