Expand description

What a backdrop blur paints: the frost, the lens over it, and its tint. A struct rather than arguments so a new knob does not change every caller.

Fields§

§blur_radius: Pixels

Gaussian sigma applied to the snapshot. Zero skips the blur entirely.

§lens: Pixels

How deep the lens profile reaches in from the rim. Zero paints flat.

§reach: Pixels

The furthest the rim may drag the backdrop. The dome’s tilt runs to vertical at the rim, so the displacement needs a bound of its own.

§magnify: f32

Displacement amplitude; signed, so its sign picks the direction.

§dispersion: f32

Per-channel spread of the displacement — the chromatic fringe.

§gain: f32

Slope of out = gain * saturated(backdrop) + tint.

§saturation: f32

How far the backdrop’s chroma is pushed from its own grey, before the gain drops the level. 1 passes it through.

§tint: Hsla

Its offset, added.

§edge: f32

How much white the lit rim adds, 0..1.

§edge_width: Pixels

How far in that light falls off to nothing.

§edge_aa: Pixels

Width of the coverage ramp at the shape’s boundary. Zero is a hard edge.
