-
- =head1 SYNOPSIS
-
- use Tk::Animation
- my $img = $widget->Animation('-format' => 'gif', -file => 'somefile.gif');
-
- $img->add_frame(@images);
-
- $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->blank( $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 $period is omitted 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.
-
- By default Animation leaves the previous movie frame in the animation
- photo. Many times overlaying subsequent frames produces a composite
- that looks blurred. The C<blank> method is used to blank the
- animation photo before displaying new frames. The default is 0 for
- backward compatibility.
-
- =head1 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.
