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:
advi -safer file.dvi
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: 1.10
available at http://advi.inria.fr/
CURRENTLY SUPPORTED FEATURES:
=============================
+ 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
+ Display of inlined Postscript using gs
+ Font antialiasing that takes background colors into account
+ Page display is interrupted on user input
+ Resizing the page adjusts the magnification

INVOCATION
==========
The invocation is
advi [OPTIONS...] DVIFILE
where OPTIONS are:
-safer Safer mode: external applications are not launched
-geometry GEOM Sets the (maximum) geometry GEOM
-g GEOM Same as -geometry GEOM
-crop Crop the window to the best size (default)
-nocrop Disable cropping
-nomargins Suppress horizontal and vertical margins
-hmargin DIMEN Horizontal margin (default: 1cm)
-vmargin DIMEN Vertical margin (default: 1cm)
-A Set Postscript antialias
-bg Draw in the background
-fullwidth Adjust size to width
-html STRING Make advi start at html reference of name STRING
-nogs Turn off dipslay of inlined Postscript
-nopauses Swictch pauses off
-page INT Make advi start at page INT
-pager STRING Command to call the pager
-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.
Currently supported units are the standard TeX units as specified in
the TeXbook (D. Knuth, Addison-Wesley, (C) 1986):
`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
fullscreen screen or reset the page to the default size (this
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
page. Does nothing if the left part of the page is
already displayed
l page righ t - 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
page. Jumps to the top of next page, if there is
one, and if the bottom of the page is already
displayed.
k page up - Moves one screen height toward the top of the
page. Jumps to the bottom previous page, if there
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.
Switching views
---------------
w switch - Switch view between master and client (if any).
W sync - Goto page of client view corresponding to page of
master view.
^W autoswitch - Toggle autoswitch flag.
Redisplay commands
------------------
r redraw - Redraw the current page to the current pause.
R reload - Reload the file and redraw the current page.
^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
----------------------------------
eturn 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.
Table of contents
-----------------
T Thumbnails - Process thumbnails.
t toc - Display thumbnails if processed, or floating table
of contents if available, or else do nothing.
Writing and drawing on the page
-------------------------------
s write - Give a pencil to scratch, typing characters on the
page.

^G laser off - When laser is on turn it off.
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
default, fonts are loaded only when needed.
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}
Delay the rendering at the point of the document for sec
seconds. Wait forever (i.e. stops) if parameter sec is omitted.
\advirecord[play]{this}{material}
Define an "advi tag" named ``this'' to refer to the text
enclosed in the following brackets. The tag can be later on
to play or replay the text. By default, [material] is not
display, unless option [play] is set.
\adviplay[color]{this}
Replay the material previously bound to {this}. If [color] is
provided changes the drawing color to [color] before displaying.
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.
