Struct slint::platform::software_renderer::PremultipliedRgbaColor

pub struct PremultipliedRgbaColor {
    pub red: u8,
    pub green: u8,
    pub blue: u8,
    pub alpha: u8,
}

Expand description

A color whose component have been pre-multiplied by alpha

The renderer operates faster on pre-multiplied color since it caches the multiplication of its component

PremultipliedRgbaColor can be constructed from a Color with the From trait. This conversion will pre-multiply the color components

impl<T> Downcast for Twhere T: Any,

§

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

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.

§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

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

§

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.

§

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.
