Tk::Animation - Display sequence of Tk::Photo images
use Tk::Animation my $img = $widget->Animation('-format' => 'gif', -file => 'somefile.gif'); $img->add_frames(@images); $img->start_animation($period); $img->stop_animation;
In the simple case when
Animation is passed a GIF89 style GIF with multiple 'frames', it will build an internal array of
add_frames method adds images to the sequence. It is provided to allow animations to be constructed from separate images. All images must be
Photos and should all be the same size.
start_animation($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.
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.
