Struct Cicp

pub struct Cicp {
    pub primaries: CicpColorPrimaries,
    pub transfer: CicpTransferCharacteristics,
    pub matrix: CicpMatrixCoefficients,
    pub full_range: CicpVideoFullRangeFlag,
}

Fields

primaries: CicpColorPrimaries

Defines the exact color of red, green, blue primary colors.

transfer: CicpTransferCharacteristics

The electro-optical transfer function (EOTF) that maps color components to linear values.

matrix: CicpMatrixCoefficients

A matrix between linear values and primary color representation.

For an RGB space this is the identity matrix.

full_range: CicpVideoFullRangeFlag

Whether the color components use all bits of the encoded values, or have headroom.

For compute purposes, image only supports CicpVideoFullRangeFlag::FullRange and you get errors when trying to pass a non-full-range color profile to transform APIs such as DynamicImage::apply_color_space or CicpTransform::new.

Implementations

impl Cicp

pub const SRGB: Cicp

The sRGB color space, BT.709 transfer function and D65 whitepoint.

pub const SRGB_LINEAR: Cicp

SRGB primaries and whitepoint with linear samples.

pub const DISPLAY_P3: Cicp

The Display-P3 color space, a wide-gamut choice with SMPTE RP 432-2 primaries.

Note that this modern Display P3 uses a D65 whitepoint. Use the primaries SmpteRp431 for the previous standard. The advantage of the new standard is the color system shares its whitepoint with sRGB and BT.2020.

Trait Implementations

impl Clone for Cicp

fn clone(&self) -> Cicp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cicp

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

Formats the value using the given formatter.

impl From<CicpRgb> for Cicp

fn from(cicp: CicpRgb) -> Cicp

Converts to this type from the input type.

impl Hash for Cicp

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 PartialEq for Cicp

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