Enum RenderingIntent 

pub enum RenderingIntent {
    Perceptual,
    RelativeColorimetric,
    Saturation,
    AbsoluteColorimetric,
}

ICC rendering intent controlling out-of-gamut color mapping.

When converting colors between profiles with different gamuts, the rendering intent determines how colors outside the destination gamut are handled. Each intent makes a different trade-off between accuracy and aesthetics.

Examples

use appthere_color::RenderingIntent;

let intent = RenderingIntent::Perceptual;
assert_eq!(intent, RenderingIntent::Perceptual);

Variants

Perceptual

Perceptual intent — optimizes for pleasing visual appearance.

Compresses the entire source gamut to fit within the destination gamut, preserving the relationships between colors. Best for photographic images where visual quality matters more than exact color matching.

RelativeColorimetric

Relative colorimetric intent — matches in-gamut colors exactly.

Maps the source white point to the destination white point and maps in-gamut colors exactly. Out-of-gamut colors are clipped to the nearest reproducible color. Best for proofing and logo colors.

Saturation

Saturation intent — maximizes color vividness.

Maps saturated source colors to saturated destination colors, prioritizing vividness over accuracy. Best for business graphics and charts where impact matters more than fidelity.

AbsoluteColorimetric

Absolute colorimetric intent — preserves exact colorimetry.

Like relative colorimetric but does not adjust for the destination white point. Colors are reproduced with absolute fidelity, including the media white point simulation. Best for exact color matching and substrate simulation in proofing.

Implementations

impl RenderingIntent

pub fn to_moxcms(self) -> RenderingIntent

Converts this rendering intent to the corresponding moxcms intent.

Examples

use appthere_color::RenderingIntent;

let intent = RenderingIntent::Perceptual;
let moxcms_intent = intent.to_moxcms();

pub fn from_moxcms(intent: RenderingIntent) -> Self

Creates a rendering intent from the corresponding moxcms intent.

Examples

use appthere_color::RenderingIntent;

let intent = RenderingIntent::from_moxcms(moxcms::RenderingIntent::Perceptual);
assert_eq!(intent, RenderingIntent::Perceptual);

Trait Implementations

impl Clone for RenderingIntent

fn clone(&self) -> RenderingIntent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RenderingIntent

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

Formats the value using the given formatter.

impl Default for RenderingIntent

fn default() -> Self

Returns RenderingIntent::Perceptual as the default.

impl<'de> Deserialize<'de> for RenderingIntent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for RenderingIntent

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

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 PartialEq for RenderingIntent

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