Enum QuantizeMethod 

pub enum QuantizeMethod {
    CustomPalette(PaletteInColorSpace),
    Wu,
    Kmeans(KmeansOptions),
}

The set of supported color quantization methods.

If the kmeans feature is enabled, then support will be added for that method. Otherwise, only Wu’s color quantization method and custom palettes are supported.

See the descriptions on each enum variant for more information.

Variants

CustomPalette(PaletteInColorSpace)

Quantize an image into a custom color palette.

This method will simply map each pixel to its closest color in the palette.

Wu

Wu’s color quantizer (Greedy Orthogonal Bipartitioning).

This method is quick and gives good or at least decent results.

See the wu module for more details.

Kmeans(KmeansOptions)

Color quantization using k-means clustering.

This method is slower than Wu’s color quantizer but gives more accurate results.

See the kmeans module for more details.

Implementations

impl QuantizeMethod

pub const fn kmeans() -> Self

Create a new QuantizeMethod::Kmeans with the default KmeansOptions.

Trait Implementations

impl Clone for QuantizeMethod

fn clone(&self) -> QuantizeMethod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuantizeMethod

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

Formats the value using the given formatter.

impl From<KmeansOptions> for QuantizeMethod

Available on crate feature kmeans only.

fn from(options: KmeansOptions) -> Self

Converts to this type from the input type.

impl From<PaletteBuf<Oklab>> for QuantizeMethod

fn from(palette: PaletteBuf<Oklab>) -> Self

Converts to this type from the input type.

impl From<PaletteBuf<Rgb<Srgb, u8>>> for QuantizeMethod

fn from(palette: PaletteBuf<Srgb<u8>>) -> Self

Converts to this type from the input type.

impl From<PaletteInColorSpace> for QuantizeMethod

fn from(palette: PaletteInColorSpace) -> Self

Converts to this type from the input type.

impl PartialEq for QuantizeMethod

fn eq(&self, other: &QuantizeMethod) -> 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 TryFrom<Vec<Oklab>> for QuantizeMethod

type Error = CreatePaletteBufError<Oklab>

The type returned in the event of a conversion error.

fn try_from(colors: Vec<Oklab>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Vec<Rgb<Srgb, u8>>> for QuantizeMethod

type Error = CreatePaletteBufError<Rgb<Srgb, u8>>

The type returned in the event of a conversion error.

fn try_from(colors: Vec<Srgb<u8>>) -> Result<Self, Self::Error>

Performs the conversion.
