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
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
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
Start displaying at a given page or at a given link reference
The file is reloading on signal SIGUSR1
Active areas (execute an action when the mouse is over)
Background colors and images
Alpha blending for images

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.
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
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 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 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.
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.
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
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.
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. 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
^X-l toggle laser - Toggle the laser beam to point 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
