-=head1 NAME
-
-Tk::Animation - Display sequence of Tk::Photo images
-
-=for pm Tk/Animation.pm
-
-=for category Tk Image Classes
-
-=head1 SYNOPSIS
-
- use Tk::Animation
- my $img = $widget->Animation('-format' => 'gif', -file => 'somefile.gif');
-
- $img->add_frame(@images);
-
- $img->start_animation;
- $img->start_animation( $period );
-
- $img->next_image;
- $img->prev_image;
- $img->set_image( 0 .. $#frames );
-
- $img->pause_animation;
- $img->resume_animation( $period );
-
- $img->fast_forward( $multiplier );
- $img->fast_reverse( $multiplier );
-
- $img->stop_animation;
-
- $img->set_disposal_method( $boolean );

-=head1 DESCRIPTION
-
-In the simple case when C<Animation> is passed a GIF89 style GIF with
-multiple 'frames', it will build an internal array of C<Photo> images.
-
-The C<add_frame> method adds images to the sequence. It is provided
-to allow animations to be constructed from separate images.
-All images must be C<Photo>s and should all be the same size.
-
-C<start_animation($period)> then initiates a C<repeat> with specified
-I<$period> to sequence through these images. As for raw C<repeat>
-I<$period> is in milliseconds, for a 50Hz monitor it should be at
-least 20ms. If I<$period> is omitted it is determined from the GIF
-metadata (see below), or if this is not possible it defaults to 100
-milliseconds.
-
-C<stop_animation> cancels the C<repeat> and resets the image to the first
-image in the sequence.
-
-For fine-grained control C<next_image> and C<prev_image> move one frame forward
-or backward. C<set_image> randomly positions the animation to a particular frame.
-
-C<pause_animation> pauses the movie and C<resume_animation> continues from the
-pause point.
-
-C<fast_forward> and C<fast_reverse> speed through the movie either
-forwards or backwards. $multiplier specifies how much faster the
-animation moves.
-
-If L<Image::Info> is installed, then the repeat period time and
-disposal method of GIF animations are determined from the GIF metadata
-directly. Otherwise the disposal method must be set manually by using
-C<set_disposal_method> (1 for blanking the previous images, 0 for
-leaving the previous images as is). The repeat period time may be
-given in the C<start_animation> method.
-
-=head1 NOTES
-
-C<set_disposal_method> was formerly known as C<blank> method, but the
-naming of this method was a mistake.
-
-If the disposal method is not set correctly, either by
-C<set_disposal_method> or by determining from the GIF metadata, then
-the following may happen: By default Animation leaves the previous
-movie frame in the animation photo. Many times overlaying subsequent
-frames produces a composite that looks blurred.
-
-=head1 BUGS
-
-This module should not depend on a module which is not declared as a
-dependency (Image::Info).
-
-The delays between images may vary in a GIF animation. This cannot be
-handled by this module yet.
-
-The handling of the various disposal methods is not correct.
