Struct Presenter

Source

pub struct Presenter { /* private fields */ }

Expand description

GPU side of showing 2D frames: one pipeline per filter pass, the frame texture, the intermediate image of two-pass filters and two uniforms with the sizes (for the pass into the output, and for a first pass into mid).

Implementations§

Source §

impl Presenter

Source

pub fn new(gpu: &Gpu) -> Presenter

Source

pub fn draw( &mut self, gpu: &Gpu, encoder: &mut CommandEncoder, view: &TextureView, size: (u32, u32), frame: VideoFrame<'_>, opts: Present, )

Draw a w×h RGBA frame at display aspect aspect (None: square pixels) letterboxed into view, an output of size pixels.

impl<T> Downcast for T
where T: Any,

Source §

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

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
