rendering intents

See the ICC.1:2022 specification from the International Color Consortium for more details about rendering intents.

The principles of ICC defined rendering intents apply with all types of image descriptions, not only those with ICC file profiles.

Compositors must support the perceptual rendering intent. Other rendering intents are optional.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Perceptual = 0

perceptual

Relative = 1

media-relative colorimetric

Saturation = 2

saturation

Absolute = 3

ICC-absolute colorimetric

RelativeBpc = 4

media-relative colorimetric + black point compensation

AbsoluteNoAdaptation = 5

ICC-absolute colorimetric without adaptation

This rendering intent is a modified absolute rendering intent that assumes the viewer is not adapted to the display white point, so no chromatic adaptation between surface and display is done. This can be useful for color proofing applications.

Trait Implementations

impl Clone for RenderIntent

fn clone(&self) -> RenderIntent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RenderIntent

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

Formats the value using the given formatter.

impl Hash for RenderIntent

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for RenderIntent

fn cmp(&self, other: &RenderIntent) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RenderIntent

fn eq(&self, other: &RenderIntent) -> 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 PartialOrd for RenderIntent

fn partial_cmp(&self, other: &RenderIntent) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<u32> for RenderIntent

type Error = ()

The type returned in the event of a conversion error.

fn try_from(val: u32) -> Result<RenderIntent, ()>

Performs the conversion.

impl Copy for RenderIntent

impl Eq for RenderIntent

impl StructuralPartialEq for RenderIntent
