Struct SdrToHdrConfig 

pub struct SdrToHdrConfig {
    pub target_peak_nits: f64,
    pub source_peak_nits: f64,
    pub highlight_gain: f64,
    pub midtone_boost: f64,
}

Configuration for SDR→HDR inverse tonemapping.

Fields

target_peak_nits: f64

Target peak luminance for the HDR output (cd/m²).

source_peak_nits: f64

Source peak luminance of the SDR content (cd/m²).

highlight_gain: f64

Highlight expansion gain (1.0 = linear, >1.0 = brighter highlights).

midtone_boost: f64

Mid-tone boost factor (subtle lift to mid-tones).

Implementations

impl SdrToHdrConfig

pub fn default_1000nit() -> Self

Creates a default SDR→HDR config targeting 1000 nit output.

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

Validates the inverse tonemapping configuration.

Errors

Returns HdrError::OutOfRange if any value is outside valid range.

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

Applies inverse tonemapping to an SDR linear-light value.

Returns the expanded HDR value in cd/m².

Trait Implementations

impl Clone for SdrToHdrConfig

fn clone(&self) -> SdrToHdrConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SdrToHdrConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SdrToHdrConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SdrToHdrConfig

fn eq(&self, other: &SdrToHdrConfig) -> 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 SdrToHdrConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
