Implementations

impl ImageAnimationState

pub fn new(image: Arc<RasterImage>, last_update_time: f64) -> Self

pub fn image_key(&self) -> Option<ImageKey>

pub fn duration_to_next_frame(&self, now: f64) -> Duration

pub fn update_frame_for_animation_timeline_value(&mut self, now: f64) -> bool

check whether image active frame need to be updated given current time, return true if there are image that need to be updated. false otherwise.
