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

       The  program  dvispc  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>.
       For  more  information, please refer to dvispc-en.txt (in English) and dvispc-ja.txt (in Japanese) on our
       GitHub repository, <https://github.com/texjporg/tex-jp-build> (under source/texk/dviout-util directory).

                                                                                                       DVISPC(1)

Dvispc is a utility to modify/edit TeX DVI file with the following features:

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

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

           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-independent 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.

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

dviselect(1), dvidvi(1), dvips(1), dvipdfmx(1)

       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.
