Immutable capture description shared by its paired scene boundaries.

Fields

blur_quality: LayerBlurQuality

Working resolution policy for subtree blur.

blur_radius: ScaledPixels

Gaussian support radius in device pixels, in [0,64].

blend_mode: LayerBlendMode

Destination blend for the completed group.

bounds: Bounds<ScaledPixels>

Source sampling rectangle, including any halo; bounded by the viewport/parent.

clip: Option<Bounds<ScaledPixels>>

Visible output clip, applied after filtering. None uses the source bounds.

opacity: f32

Opacity of the completed group, including inherited opacity exactly once.

saturation: f32

Capture-domain saturation in [0,2], with 0 grayscale and 1 unchanged.

brightness: f32

Capture-domain brightness multiplier in [0,2].

contrast: f32

Capture-domain contrast in [0,2], centered on straight RGB 0.5.

invert: f32

Inversion strength in [0,1], with 0 unchanged and 1 complemented RGB.

program: Arc<SceneShaderProgram>

Shared capture/composition shader. Metal wide captures set viewport.w to 2 for extended linear-P3 filtering; 1 retains bounded P3, and 0 encoded sRGB.

Trait Implementations

impl Debug for LayerCapture

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
