Struct RecordedBackdrop 

pub struct RecordedBackdrop {
    pub image: ImageData,
    pub bounds: Rect,
    pub blur_px: f64,
    pub sampling: Sampling,
    pub cell_px: f64,
    pub refraction: Refraction,
    pub legible: Legible,
    pub layer: u32,
    pub below: Scene,
    pub ground: AlphaColor<Srgb>,
}

One surface drawn in the blurred material while a recording was active, in the recording’s coordinates.

Fields

image: ImageData

The placeholder the scene draws for the blurred backdrop.

bounds: Rect

The surface’s bounds.

blur_px: f64

Blur standard deviation in recording pixels.

sampling: Sampling

How the sample is filtered after the blur.

cell_px: f64

The cell’s side in recording pixels, for crate::part_paint::Sampling::Blocky.

refraction: Refraction

How the backdrop is bent, in recording pixels.

legible: Legible

The range what shows through is compressed into.

layer: u32

The layer of the scene the surface was drawn into (see layer_scene).

below: Scene

What that scene held before the surface, with the layers still open there ended: a balanced scene of its own.

ground: AlphaColor<Srgb>

The opaque panel ground the material tints with.

Implementations

impl RecordedBackdrop

pub fn into_region( self, rect: Rect, scale: f64, below: impl FnOnce(Scene) -> Scene, ) -> BackdropRegion

This surface’s backdrop as a region of a target that draws it at rect, scale target pixels per recording pixel, over below (handed what the recording saw below the surface). The one mapping from a recording to a region, so a field the pass reads is never left behind on the way.

pub fn reach(&self) -> f64

How far outside its bounds the surface’s blurred pixels depend on what is drawn: the kernel’s reach, and what the halved passes’ texels add to it (at most a quarter of the deviation, twice over, once a texel is that large).

Trait Implementations

impl Clone for RecordedBackdrop

fn clone(&self) -> RecordedBackdrop

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
