Struct WaveformLayout 

pub struct WaveformLayout {
    pub origin_x: f32,
    pub baseline_y: f32,
    pub bar_width: f32,
    pub bar_gap: f32,
    pub max_height: f32,
    pub color: [f32; 4],
    pub metric: BarMetric,
    pub mode: WaveformDisplayMode,
}

Layout parameters shared by every bar in one waveform.

All values use the caller’s chosen unit system (NDC, pixels, …).

Fields

origin_x: f32

x of the first bar’s left edge.

baseline_y: f32

Reference y line for WaveformDisplayMode.

bar_width: f32

Width of one bar (excluding gap). Must be > 0.

bar_gap: f32

Horizontal spacing between adjacent bar left edges, on top of bar_width. May be 0 for touching bars.

max_height: f32

Bar height when the metric is 1.0. Must be > 0.

color: [f32; 4]

Per-bar RGBA color.

metric: BarMetric

Whether to read peak or rms from each bucket.

mode: WaveformDisplayMode

Anchored vs mirrored.

Implementations

impl WaveformLayout

pub fn ndc_default() -> Self

Reasonable defaults for an NDC [-1, +1] mono waveform centered vertically: gray bars 0.02 wide, gap 0.005, max height 0.4, anchored at y = 0. Tweak from here.
