Struct HeadlessOptions 

pub struct HeadlessOptions {
    pub dpr: f32,
    pub ticks: Option<u64>,
}

Options specific to the rendered headless mode. Sizing comes from RunOptions::size / lumen.toml [window] size exactly like the windowed path, so it is not duplicated here.

Fields

dpr: f32

Device pixel ratio for the offscreen target. Viewport.size stays logical (like the windowed path); the render texture - and thus every screenshot - is logical x dpr physical pixels.

ticks: Option<u64>

Some(n): run exactly n ticks back-to-back, then take the graceful-close path and return. None: run until SIGINT/SIGTERM.
