ANIMATION(1)

NAME
Tk::Animation - Display sequence of Tk::Photo images

SYNOPSIS
  use Tk::Animation
  my $img = $widget->Animation('-format' => 'gif', -file => 'somefile.gif');
  $img->add_frames(@images);
  $img->start_animation($period);
  $img->stop_animation;

DESCRIPTION
In the simple case when "Animation" is passed a GIF89 style GIF with multiple 'frames', it will build an internal array of "Photo" images.

The "add_frames" method adds images to the sequence. It is provided to allow animations to be constructed from separate images. All images must be "Photo"s and should all be the same size.

"start_animation($period)" then initiates a "repeat" with specified $period to sequence through these images. As for raw "repeat" $period is in milli-seconds, for a 50Hz monitor it should be at least 20mS.

"stop_animation" cancels the "repeat" and resets the image to the first image in the sequence.

BUGS
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.
