Struct normal_map::PowerMapF64

pub struct PowerMapF64 { /* fields omitted */ }

Exponential mapping where the normalized value is raised to the supplied exponent.

Please note if you use Unit::Decibels, then the decibels will be linearly mapped, not the raw amplitude.

Implementations

impl PowerMapF64

pub fn new(min: f64, max: f64, exponent: f64, unit: Unit) -> Self

Create a new PowerMapF64 for exponential mapping where the normalized value is raised to the supplied exponent.

Please note if you use Unit::Decibels, then the decibels are what will be mapped, not the raw amplitude.

Arguments

• min - the minimum of the range
• max - the maximum of the range
• exponent - the exponent to raise the normalized value to
• unit - the type of unit

Panics

• Panics when exponent = 0.0.

pub fn normalize(&self, value: f64) -> f64

Map an f64 value to the normalized range [0.0, 1.0].

pub fn normalize_array(&self, in_values: &[f64], out_normalized: &mut [f64])

Map an array of f64 values to the normalized range [0.0, 1.0].

Values will be processed up to the length of the shortest array.

pub fn denormalize(&self, normalized: f64) -> f64

Un-map a normalized value to the corresponding f64 value.

pub fn denormalize_array(&self, in_normalized: &[f64], out_values: &mut [f64])

Un-map an array of normalized values to the corresponding f64 value.

Values will be processed up to the length of the shortest array.
