Tk::Animation - Display sequence of Tk::Photo images
use Tk::Animation my $img = $widget->Animation('-format' => 'gif', -file => 'somefile.gif'); $img->add_frame(@images); $img->start_animation($period); $img->stop_animation;
In the simple case when Animation is passed a GIF89 style GIF with multiple 'frames', it will build an internal array of Photo images.
Animation
Photo
The add_frame method adds images to the sequence. It is provided to allow animations to be constructed from separate images. All images must be Photos and should all be the same size.
add_frame
start_animation($period) then initiates a repeat with specified $period to sequence through these images. As for raw repeat $period is in milli-seconds, for a 50Hz monitor it should be at least 20mS.
start_animation($period)
repeat
stop_animation cancels the repeat and resets the image to the first image in the sequence.
stop_animation
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.
