advi

NAME

advi -- a DVI previewer and presenter with some eye candy effects for presentation.

The advi program is a viewer for DVI files that also recognizes a new class of special's targeted to presentations via laptop computers: various visual effects can easily be incorporated to the presentation, via a companion advi.sty LaTeX package. If the input dvifile is a DVI file that has been compressed with gzip(1) or bzip2(1) it will be automatically decompressed.

advi is also a full-fledged graphical presenter that provides a wealth of effects via embedded applications. Embedded applications are arbitrary Unix programs that are launched on demand during the presentation; an embedded application may display its material on a devoted area of the slide, leading for example to live and/or interactive demos during the presentation.

CURRENTLY SUPPORTED FEATURES:

- Encapsulated Postscript File inclusion (using graphics package)

- Effects for presentation (pause, delay, text color change)

- Embedded applications for interactive demonstration

- Pictures visualization via gpic(1) specials

- Display of inlined Postscript using gs(1)

- 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

- Hyperlinks to other pages or slides

- Active areas (execute an action when the mouse is over)

- Background colors and images

- Alpha blending for images

- Bubbles, active anchors, annotations

- Init files to set up options

- Safety policy for embedded application

- Scratching (interactive drawing and writing on slides during presentation)

- Floating table of contents (either as hyperlinks on a regular LaTeX table of contents or as small images set up on a page)

- Transitions (slide animations when changing pages)

- Text movements

- Integrated ``Laser pointer'' feature to point to the slide

Notice that advi needs the kpsewhich(1) tool in order to find and recompile PK fonts. (This program is part of the `kpathsea' library provided by many TeX distributions.)

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 keystrokes when typed in its window. Some of them may optionally be preceded by a number, called ARG below, whose interpretation is keystroke dependent. If ARG is unset, its value is 1.

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

?: Quick info and key bindings help.

q: Quits the program.

^X-^C (Control-X Control-C): Quits the program.

^X-^F (Control-X Control-F): Turn to full screen mode.

^F (Control-F): Toggle to switch from full screen to normal mode and converse.

^<button> (Control + left mouse button): Allow moving the page into the window (useful in full screen mode).

return: If ARG is non zero, push the current page on the history stack, and move forward ARG physical pages.

n: Move ARG physical pages forward, leaving the history unchanged.

p: Move ARG physical pages backward, leaving the history unchanged.

<tab>: Push the current page on top of the history as a marked page, do no move.

<space>: Move to the next pause if any, or do as return otherwise.

<backspace>: Move ARG pages backward according to the history. The history stack is popped, accordingly.

<escape>: Move ARG marked pages backward according to the history. Do nothing if the history does no contain any marked page.

g: 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 a marked page, and move to the physical page ARG.

,: Move to the first page.

.: Move to the last page.

c: Center the page in the window and resets the default resolution.

<: Scale the resolution by 1/scalestep (default 1/sqrt (sqrt (sqrt 2.0))).

>: Scale the resolution by scalestep (default sqrt (sqrt (sqrt 2.0))).

f: Load all the fonts used in the documents. By default, fonts are loaded only when needed.

F: Does the same as `f', and precomputes the glyphs of all characters used in the document. This takes more time than loading the fonts, but the pages are drawn faster.

r: Redraw the current page.

R: Reload the file and redraw the current page.

C: Erase the image cache.

T: Process thumbnails (graphical table of contents for the show).

t: Display thumbnails if processed or floating table of contents, or do nothing.

^X-l (Control-X l): Toggle on or off the laser pointer.

s: Turn on the write scratching mode (to interactively write on the slide). When in scratching mode press ? to get help.

S: Turn on the draw scratching mode (to interactively draw on the slide). When in scratching mode press ? to get help.

^X-^S (Control-X Control-S): Save an image of the current state of the slide. The default image file name is shot <n> where <n> is the next available integer number such that no previously saved slide image is overwritten. The default image format is PNG which is the extension of the image file.

A click on an hyperlink, push the current page on this history as marked (unless the target page is the current page) and move to the target page. If the target is visible, it highlights the target.

Moreover, the user can drag the currently displayed page in the window in order to change its relative position. (This is useful when the page is displayed at a resolution such that it cannot fit in the window.)

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. For the casual user, the advi-slides.sty package gives a truly simple way to write a show for advi (see in the examples directory or the documentation inside the advi-slides.sty file for more information).

\adviwait: Active-DVI stops rendering at the point of the document and wait a user key stroke.

\adviwait{sec}: Delay the rendering at the point of the document for sec seconds.

\advirecord[play]{this}{material}: Define an "advi tag" named ``this'' to refer to the text enclosed in the following brackets. The tag can be used to change the color of the text later.

\advirecord{this}{material}: Same as \advirecord[play]{this}{material}, but does not render the text at this point. You can display the text later, using the \adviplay macro.

\adviplay{this}: Display the texts associated with the tag ``this''.

\adviplay[col]{this}: Display the texts associated with the tag ``this'', using the color ``col''.

The directory examples contains a lot of presentations. Please look also at test/demo*.{tex|dvi} and test/macros.{tex|dvi} for a rather comprehensive demonstration of Active-DVI capabilities.
