use Tk::Animation
my $img = $widget->Animation('-format' => 'gif', -file => 'somefile.gif');</PRE>

$img->start_animation($period);

<H1><A NAME="description">DESCRIPTION</A></H1>
<P>In the simple case when <CODE>Animation</CODE> is passed a GIF89 style GIF with
multiple 'frames', it will build an internal array of <CODE>Photo</CODE> images.</P>
<P><CODE>start_animation($period)</CODE> then initiates a <CODE>repeat</CODE> with specified <EM>$period</EM>
to sequence through these images.</P>
<P><CODE>stop_animation</CODE> cancels the <CODE>repeat</CODE> and resets the image to the first
image in the sequence.</P>
<P>The <CODE>add_frames</CODE> method adds images to the sequence. It is provided
to allow animations to be constructed from separate images.
All images must be <CODE>Photo</CODE>s and should all be the same size.</P>
<P>
<HR>
<H1><A NAME="bugs">BUGS</A></H1>
<P>The 'period' should probably be a property of the Animation object
rather than specified at 'start' time. It may even be embedded
in the GIF.</P>
