WARNING

    advi -safer file.dvi

Active-DVI plays the DVI files that is displays: during presentation advi can launch arbitrary commands that were incorporated into the LaTeX source of the DVI file to animate the presentation. Hence, when playing a DVI file from some untrusted source, you must use the -safer option that prevents the execution of embedded commands:

For instance, if you choose advi as your default application to view DVI files, the safe entry for your .mailcap file is

    application/x-dvi; advi -safer %s

It is also recommended to check before visualisation the list of embedded commands that a suspicious DVI file could execute by calling

    advi -n file.dvi

Presentation

Active-DVI is a DVI previewer and presenter written in Objective Caml (http://caml.inria.fr/ocaml/) with some eye candy effects for presentation, support for interactive demonstrations, and embedding of arbitrary applications within the presentation (hence the Active adjective of the presenter :).

Active-DVI is largely based on Mldvi written by Alexandre Miquel (http://www.pps.jussieu.fr/~miquel/).

Version: 2.0.0 available at http://advi.inria.fr/

Comparitble with the pgf package and beamer class.
Encapsulated Postscript File inclusion (using graphics package)
Effects for presentation (pause, delay, text color change)
Embedded applications for interactive demonstration
Pictures visualization via gpic specials

    advi [OPTIONS...] DVIFILE

where OPTIONS are:

  -crop                 Crop the window to the best size (default)
  -nocrop               Disable cropping
  -nomargins            Suppress horizontal and vertical margins
  -hmargin DIMEN        Horizontal margin  (default: 1cm)

  -safer                Safer mode: external applications are not launched
  -scalestep REAL       Scale step for '<' and '>' (default sqrt (sqrt (sqrt 2.0)))

Geometry GEOM is specified in pixels, using the standard format for specifying geometries (i.e: "WIDTHxHEIGHT[+XOFFSET+YOFFSET]").

Dimensions (for options -hmargin' and -vmargin') are specified as numbers optionally followed by two letters representing units.

When no units are given, dimensions are treated as numbers of pixels.

  `pt' (point), `pc' (pica), `in' (inch), `bp' (big point),
  `cm' (centimeter), `mm' (millimeter), `dd' (didot point),
  `cc' (cicero) and `sp' (scaled point).

Note that dimensions are specified w.r.t the original TeX document, and do not correspond to what is actually shown on the screen, which can be displayed at a different resolution than specified in the original TeX source.

KEYSTROKES

Advi recognizes the following main keystrokes when typed in its window. (See the documentation for the complete list of bindings.) Each may optionally be preceded by a number, called ARG below, whose interpretation is keystroke dependant. If ARG is unset, its value is 1, unless specified otherwise.

Advi maintains an history of previously visited pages organized as a stack. Additionnally, the history contains mark pages which are stronger than unmarked pages.

Survival command kit

  ?     info        - This quick info and key bindings help.
  q     quit        - End of show.
  space continue    - Move forward (arg pauses forward if any, or do as
                      return otherwise).
  ^X-^C quit        - End of show.

Moving between pages

  n     next        - Move arg physical pages forward, leaving the
                      history unchanged.
  p     previous    - Move arg physical pages backward, leaving the
                      history unchanged.
  ,     begin       - Move to the first page.
  .     end         - Move to the last page.
  g     go          - If arg is unset move to the last page. If arg is
                      the current page do nothing. Otherwise, push the
                      current page on the history as marked, and move to
                      physical page arg .

Moving between pauses

  N  next pause     - Move arg pauses forward (equivalent to continue).
  P  previous pause - Move arg pauses backward.

Adjusting the page size

  ^X-^F set         - Adjust the size of the page to fit the entire
        fullscreen    screen.
  ^F    toggle      - Adjust the size of the page to fit the entire

                      is a toggle).
  <     smaller     - Scale down the resolution by scalestep (default
                      (((2)^1/2)^1/2)^1/2).
  >     bigger      - Scale up the resolution by scalestep (default
                      (((2)^1/2)^1/2)^1/2).
  #     fullpage    - Remove margins around the page and change the
                      resolution accordingly.
  c     center      - Center the page in the window, and resets the
                      default resolution.

Moving the page in the window

  h     page left   - Moves one screen width toward the left of the

                      already displayed
  l     page right  - Moves one screen width toward the right of the
                      page. Does nothing if the right part of the page
                      is already displayed
  j     page down   - Moves one screen height toward the bottom of the

                      is one, and if the top of the page is already
                      displayed.

  ^left  move page  - A black line draws the page borders; moving the
  button              mouse then moves the page in the window.
  ^C    toggle      - Toggles center-on-cursor flag, which when sets
        center on     moves the screen  automatically so that the cursor
        cursor        appears on the screen.

  ^L    redisplay   - Redisplay the current page to the first pause of
                      the page.
  a  active/passive - toggle advi effects (so that reloading is silent).

Using the navigation history stack

  return  forward   - Push the current page on the history stack, and
                      move forward n physical pages.
  tab    mark+next  - Push the current page on the history as marked,
                      and move forward n physical pages.
  backspace back    - Move arg pages backward according to the history.
                      The history stack is poped, accordingly.
  escape  find mark - Move arg marked pages backward according to the
                      history. Do nothing if the history does no contain
                      any marked page.

Writing and drawing on the page

  s     write       - Give a pencil to scratch, typing characters on the

  S     draw        - Give a spray can to scratch, drawing on the page.
  ?     info        - While in scratch mode, press ? for more info.

Using the laser pointer

Saving the current page

  ^X-^S save page   - Save the current page as an image file.

Dealing with caches

  f     load fonts  - Load all the fonts used in the document. By

  F     make fonts  - Does the same as f, and precomputes the glyphs of
                      all the characters used in the document. This
                      takes more time than loading the fonts, but the
                      pages are drawn faster.
  C     clear       - Erase the image cache.

EYE CANDY MACROS

Using the LaTeX style advi.sty provided with the package, you can embed some Active-DVI specials into your TeX documents. Advi interprets those specials to provide some eye candy features for your presentation:

    `\wait{sec}`

    \advirecord[play]{this}{material}

    \adviplay[color]{this}

Please look at doc/manula.dvi for more information. Look in directory test for examples (try advi test/*.dvi). Advanced examples are in directory examples. (See examples/seminar/clock/tools.dvi, examples/prosper/LL/ll.dvi, examples/prosper/Join/join.dvi.)
