<A HREF=../index.html>Portable Presenter</A> currently has only
one style of dynamics: the default.<BR>
<P>
The <A HREF=../formatter/index.html>formatter</A> provides the
user with a way to specify dynamics on part of text and images.
The formatter passes these strings to this module, which interprets
the string into a <A HREF=../program/index.html>program</A> which
can be run when the <A HREF=../slideview/index.html>slide-view</A>
is being displayed.
<H2>Options</H2>
The Dynamic/Default style-element contains the following options:
<DL>
<DT><B>-appear =></B> <EM>description</EM>
<DD>How the slide elements are shown by default.<BR>
The default is "<CODE>phase 0 appear</CODE>".
<P>
<DT><B>-appearTime =></B> <EM>seconds</EM>
<DD>When <CODE>from</CODE> or <CODE>to</CODE> do not carry a time
specification.
<P>
<DD>
</DL>
<H2><A NAME=syntax>Syntax</A></H2>
The exact syntax is one string containing:<BR>
<CODE>[phase-spec][after <I>secs</I>][from|to <I>dir</I> [<I>secs</I>]][appear|disappear]</CODE>
<P>
<UL>
<LI>The <B><FONT COLOR=green>phase</FONT></B>-specification can be
<DL>
<DT><B>phase </B><I>number</I> or
<B>phase </B><I>number</I><B>-</B>
<DD>Show from the specified phase of the slide onwards.
<DT><B>phase -</B><I>number</I>
<DD>Show until (including) the specified phase.
<DT><B>phase </B><I>number1</I><B>-</B><I>number2</I>
<DD>Show from phase number1 till phase number2.
</DL>
<P>
A presentation of one <A HREF=../slideview/index.html>slide-view</A>
of a slide can contain a few phases. You enter a next phase of a
<A HREF=../slide/index.html>slide</A> (all its slide-views) by pressing
the space-bar.
<P>
<LI>With <B><FONT COLOR=green>after</FONT></B>, you specify
the number of seconds from the start of the specified phase until the
appearance or disappearance of the item.
<P>
<LI>The <B><FONT COLOR=green>from</FONT></B> and
<B><FONT COLOR=green>to</FONT></B> cause text and images
to move over the screen in a certain direction. As direction can
be used any from n, ne, e, se, s, sw, w, nw.<BR>
The time tells how many seconds are to be used, which defaults to
the value of -appearTime.
<P>
<LI><B><FONT COLOR=green>appear</FONT></B> and
<B><FONT COLOR=green>disappear</FONT></B> are usually implied
by the other statements.
</UL>
<H2><A NAME=example>Examples</A></H2>
The <A HREF=../formatter/index.html>formatter</A> in use calls this
module to translate a string into a program. For instance, if you use
the <A HREF=../formatter/markup.html>markup</A>, you can specify:
<PRE>
<A SHOW="after 5 from ne">some text</A>
</PRE>
which results in a call for this module with the string
"<CODE>after 5 from ne</CODE>". This module translates this into a
command for the <A HREF=../program/index.html>program</A>, which will
result in the effect that
<UL>
<LI>the text "<CODE>some text</CODE>" will be shown
<LI>in phase 0 (default),
<LI>after 5 seconds,
<LI>entering the screen from north-east,
<LI>in <CODE>-appearTime</CODE> seconds (default).
</UL>
<P>
Other examples:
<PRE>
phase 2-3
phase -4 after 2.3 to s 8.45
phase 3 disappear
</PRE>
