Enum Scale 

pub enum Scale {
    Natural,
    Auto,
    Fixed(f64),
}

How a frame’s scalar field is mapped onto the colormap’s [0, 1] / [-1, 1] input range.

render_frame picks between the first two. The third exists for animation: auto-contrast is computed per frame, so a sequence rendered that way re-scales on every frame and the brightness visibly pumps. Holding one extent across the sequence is what makes an exported video readable.

Variants

Natural

Read values at their natural scale — f32 reprs in [0, 1] / [-1, 1], integer counts /255.

Auto

Stretch to this frame’s own robust extent (auto-contrast).

Fixed(f64)

Stretch to a caller-supplied extent, shared across however many frames the caller renders. Values beyond it clamp to the end of the colormap. A non-positive extent falls back to Scale::Natural, so a calibration pass over blank frames cannot black out a whole video.
