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


       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 [output_text_file]

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


       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,

              {color push  Black}
              {color pop}
              {color push rgb 1 0 0}
              {color pop}
              {color push  Black}
              {color pop}

       This  feature  is  equivalent  to  a  program  dvispecials in TeX-Guy package <http://www-> and dvii -s <>.

       (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.


       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:

       Other specials might be supported in the future if needed.

       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 <>.
