Struct HdrToSdrConfig 

pub struct HdrToSdrConfig {
    pub curve: TonemapCurve,
    pub source_peak_nits: f64,
    pub target_peak_nits: f64,
    pub desat_strength: f64,
}

Configuration for HDR→SDR tonemapping.

Fields

curve: TonemapCurve

Tonemapping curve.

source_peak_nits: f64

Source peak luminance (cd/m²).

target_peak_nits: f64

Target peak luminance (cd/m²) — typically 100 for SDR.

desat_strength: f64

Desaturation strength (0.0 = none, 1.0 = full grey at peak).

Implementations

impl HdrToSdrConfig

pub fn default_1000nit() -> Self

Creates a default HDR→SDR configuration for 1000 nit source.

pub fn validate(&self) -> Result<(), HdrError>

Validates the tonemapping configuration.

Errors

Returns HdrError::OutOfRange if luminance or desaturation values are invalid.

pub fn tonemap_reinhard(&self, l: f64) -> f64

Applies the Reinhard tonemapping operator to a linear-light value.

pub fn tonemap_hable(&self, l: f64) -> f64

Applies the Hable (Uncharted 2) filmic curve.

pub fn tonemap_aces(&self, l: f64) -> f64

Applies the ACES filmic curve approximation.

pub fn apply(&self, l: f64) -> f64

Applies the configured tonemapping curve to a linear-light value.

Trait Implementations

impl Clone for HdrToSdrConfig

fn clone(&self) -> HdrToSdrConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HdrToSdrConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HdrToSdrConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for HdrToSdrConfig

fn eq(&self, other: &HdrToSdrConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for HdrToSdrConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
