Struct ProPhoto 

pub struct ProPhoto;

ProPhoto ROMM RGB transfer function per ISO 22028-2:2013.

Power-law gamma 1.8 with a small linear segment near black. Used in camera raw and professional photo workflows.

Implementations

impl ProPhoto

pub const GAMMA: f32 = 1.8

Decoding gamma exponent.

pub const LINEAR_SLOPE: f32 = 16.0

Slope of the linear toe.

pub const LINEAR_THRESHOLD: f32

Linear light value at which the curve transitions to the power-law segment.

pub const ENCODED_THRESHOLD: f32

Encoded signal value at which the curve transitions to the power-law segment.

Trait Implementations

impl Clone for ProPhoto

fn clone(&self) -> ProPhoto

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProPhoto

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

Formats the value using the given formatter.

impl<F: Float> Decode<F> for ProPhoto

fn decode(x: F) -> F

Convert an encoded signal value to a linear-light value.

impl Default for ProPhoto

fn default() -> ProPhoto

Returns the “default value” for a type.

impl<F: Float> Encode<F> for ProPhoto

fn encode(x: F) -> F

Convert a linear-light value to an encoded signal value.

impl PartialEq for ProPhoto

fn eq(&self, other: &ProPhoto) -> 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.
