Variants

DeviceGray

DeviceRGB

DeviceCMYK

Lab

CIE Lab* with its white point and /Range.

Fields

wp: [f64; 3]

range: [f64; 4]

Indexed

Fields

base: Box<ColorSpace>

hival: usize

lookup: Vec<u8>

Separation

Separation / DeviceN: n tints through a function into alt.

Fields

n: usize

alt: Box<ColorSpace>

tint: Option<Function>

is_none: bool

/None: paints nothing.

is_all: bool

/All: paints every colorant — black at full tint.

Pattern(Option<Box<ColorSpace>>)

A pattern colour space, with the base space of an uncoloured (type 2) tiling pattern’s colour operands.

Implementations

impl ColorSpace

pub fn components(&self) -> usize

pub fn initial(&self) -> Vec<f64>

The initial colour when the space is selected (cs): black, or all colorants at 1.0 for Separation/DeviceN.

pub fn default_decode(&self, bpc: u32) -> Vec<f64>

The default /Decode range of image samples in this space for bpc bits: [0 1] per component, [0 2ᵇᵖᶜ−1] for Indexed, the /Range for Lab.

pub fn parse( doc: &Document, obj: &Object, res: Option<&Dictionary>, ) -> Option<ColorSpace>

Resolve a colour space object; res is the resources dictionary named spaces are looked up in.

pub fn to_rgb(&self, v: &[f64]) -> Option<[f64; 3]>

Component values → RGB in [0, 1]. None for /Separation /None (nothing is painted).

Trait Implementations

impl Clone for ColorSpace

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColorSpace

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

Formats the value using the given formatter.
