dvipos(1)                           ConTeXt                          dvipos(1)




NAME

       dvipos - compute positions in a DVI file



SYNOPSIS

       dvipos [ OPTION... ] infile[.dvi]



DESCRIPTION

       dvipos  parses a DVI file looking for pos: specials.  It currently rec-
       ognizes  pos:pxy,  pos:pxywhd,  pos:pxyplus,  pos:begbox,   pos:endbox,
       pos:beglines,  and  pos:endlines.  It then outputs the information from
       those specials along with information that  only  a  DVI  postprocessor
       could  determine,  such  as  the  current x and y location.  The output
       looks like:
          \pospxywhd{text:54}{54}{10663sp}{8535sp}{21326sp}{34081sp}{0sp}
       and is suitable for including in a tex(1) or pdftex(1) auxilliary file,
       such  as  document.tuo,  to be read in by the next run of the tex(1) or
       similar typesetting engine.



OPTIONS

       -h, --help
              print usage.

       -W, --warning
              print warnings.

       -v, --verbose
              print verbose output.

       -d, --debug
              print dvitype(1) debugging data.

       -s, --smashchars
              regard height and depth as zero.

       -o, --output=FILE
              send all output to FILE.  Without this option,  output  goes  to
              stdout.

       -b, --bbox[=FILE]
              send bounding box to FILE (default FILE is infile.pos).

       -f, --framed[=BASE]
              request  copy  of DVI file, BASE.dvi, with bounding boxes framed
              (default  FILE  is  infile_frames.dvi).   See  the   --framesize
              option.

       -m, --mag=INT
              override tex(1) magnification by INT.

       -w, --framesize=INT
              set frame rule size by INT (default 6554 = .1pt).

       -p, --pages=X:Y
              set page ranges from X to Y.



USAGE

       dvipos  is run mostly behind the scenes by ConTeXt's texexec(1) between
       runs of tex(1) or pdftex(1), in order to provide information to and get
       information  about positional graphics.  These graphics are provided by
       the MetaFun interface to mpost(1).  dvipos is not used (or  needed)  in
       PDF-output  mode but is needed for DVI-output mode.  pdftex(1) starting
       with version 1.40 can produce position information even in DVI mode, so
       once  the  ConTeXt  macros take advantage of this feature, the need for
       dvipos will fade.

       Until then, here is a typical use of dvipos:
          dvipos notes.dvi
       The position information that is output is collected by  texexec(1)  to
       include in the notes.tuo auxilliary file to use in the next run.




EXAMPLES

       Extract positions from doc.dvi, with output to doc.loc:
              dvipos -o doc.loc doc.dvi

       Same as above, but also send bbox information to doc.pos:
              dvipos -b -o doc.loc doc.dvi

       Instead send bbox information to /tmp/debug.pos:
              dvipos -b=/tmp/debug.pos -o doc.loc doc.dvi



SEE ALSO

       dvips(1), dvitype(1), mpost(1), pdftex(1), tex(1), texexec(1).

       For  more  about  positional graphics, see the MetaFun documentation on
       the ConTeXt wiki <http://wiki.contextgarden.net/MetaFun>.



BUGS

       If you specify a file for the -b option, you must join the  option  and
       name with = rather than (the more common) space:
          dvipos -b=/tmp/debug.pos notes.dvi
       works, but
          dvipos -b /tmp/debug.pos notes.dvi
       does not.
