Struct LayerHandle 

pub struct LayerHandle<'a, C> { /* private fields */ }

Provides a safe abstraction for modifying a layer configuration.

Implementations

impl<'a, C: Interpolate + Copy> LayerHandle<'a, C>

pub fn new(layer: &'a mut LayerConfig<C>) -> Self

Creates a new layer handle for the given layer configuration.

pub fn opacity(self, opacity: u8) -> Self

Sets the layer opacity.

Depending on the render target, a background color hint may need to be set to see the effect of the opacity.

See: [hint_background]

pub fn hint_background(self, color: C) -> Self

Sets a background color hint for the layer.

This is used to simulate alpha blending by interpolating the background color with the specified color based on the layer’s alpha value.

pub fn transform(self, transform: &LinearTransform) -> Self

pub fn offset(self, offset: Point) -> Self

pub fn scale(self, scale: ScaleFactor) -> Self

pub fn clip(self, clip_rect: &Rectangle) -> Self
