}

Object-safe full-frame animation decoder.

Wraps AnimationFrameDecoder for dyn dispatch. Produced by DynDecodeJob::into_animation_frame_decoder.

Downcasting

Use as_any() to downcast back to the concrete codec type for format-specific animation controls.

Required Methods

fn as_any(&self) -> &dyn Any

Downcast to the concrete frame decoder type.

fn as_any_mut(&mut self) -> &mut dyn Any

Downcast to the concrete frame decoder type (mutable).

fn into_any(self: Box<Self>) -> Box<dyn Any>

Consume and downcast to the concrete frame decoder type.

fn info(&self) -> &ImageInfo

Image metadata, available after construction.

fn frame_count(&self) -> Option<u32>

Number of frames, if known without decoding.

fn loop_count(&self) -> Option<u32>

Animation loop count from the container.

fn render_next_frame_owned( &mut self, stop: Option<&dyn Stop>, ) -> Result<Option<OwnedAnimationFrame>, BoxedError>

Render the next frame as an owned copy.

fn render_next_frame_to_sink( &mut self, stop: Option<&dyn Stop>, sink: &mut dyn DecodeRowSink, ) -> Result<Option<OutputInfo>, BoxedError>

Render the next frame directly into a caller-owned sink.
