DVIPOS
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 recognizes 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) auxiliary 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 auxiliary 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 ⟨ URL: https://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.
