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. - -=cut - |
