NAME
       dvispc - Modify a DVI file to be page-independent in specials

SYNOPSIS
       dvispc [-c] [-bvz] input_dvi_file [output_dvi_file]

       dvispc -d input_dvi_file

       dvispc -s [-p..] input_dvi_file [output_text_file]

       dvispc   -a   [-ltv]   [-J..]   [-p..]   [-r..]   input_dvi_file  [out-
       put_text_file]

       dvispc -x[..]  [-ltv] [-r..]  [input_text_file] output_dvi_file

DESCRIPTION
       Dvispc is a utility to modify/edit TeX DVI file with the following fea-
       tures:

           Mode option -c (default):
               correct  an  input  DVI to be page-independent in specials (de-
       fault)

           Mode option -d:
               dry run to check if an input DVI is  page-independent  in  spe-
       cials

           Mode option -s:
               show all specials in the input DVI

           Mode option -a:
               translate DVI into a Text (like dv2dt in dtl)

           Mode option -x:
               translate Text into a DVI (like dt2dv in dtl)

       (1)  The  main feature of dvispc is the first one, to make a page-inde-
       pendent DVI file.

       A "pure" DVI file must be actually page-independent.  However in recent
       years,  DVI  files with lots of \special's (color, annotation etc.) are
       commonly used, and they are not always page-independent. In such  case,
       for  example,  dviselect  or  dvidvi fails to preserve \special's (e.g.
       page color might be lost).

       The program dvispc corrects such page-"dependent" DVI files to be page-
       independent,  which  can be safely processed by dviselect or dvidvi and
       then properly converted to other formats such as PostScript and PDF.

       (2) To know whether such a correction is needed or not, dvispc -d  will
       suffice.

       (3) The mode -s lists all specials found in the input DVI as-is, with a
       preceding number which denotes the page where it appears.  For example,

              [1]
              {color push  Black}
              {color pop}
              {color push rgb 1 0 0}
              {color pop}
              [2]
              {color push  Black}
              {color pop}

       This feature is equivalent to a program dvispecials in TeX-Guy  package
       <http://www-masu.ist.osaka-u.ac.jp/%7Ekakugawa/TeX-Guy/>  and  dvii  -s
       <https://ctan.org/pkg/dvii>.

       (4) The mode -a and -x correspond to dv2dt and dt2dv in the dtl (=  DVI
       Text  Language)  package respectively. By default dvispc -a formats the
       output text in its own style, but DTL-compatible  format  is  available
       with -t option. Also, dvispc -x can accept DTL-compatible text input.

SUPPORTED SPECIALS
       Currently dvispc supports the followings:

           dvips-compatible specials
               color push, color pop, background
           dvipdfm(x) specials
               pdf:bcolor, pdf:ecolor, pdf:bgcolor, pdf:bann, pdf:eann
           tpic specials:
               pn

       Other specials might be supported in the future if needed.
