Implementations

impl SixelDither

pub const fn new() -> Self

Creates a new SixelDither.

pub fn create(ncolors: i32) -> Result<Self>

Creates a new SixelDither with the provided number of colors.

pub fn get(builtin_dither: BuiltinPalette) -> Result<Self>

Creates a new SixelDither from a predefined palette.

pub fn initialize( &mut self, data: &[u8], width: usize, height: usize, palette_config: PaletteConfig, ) -> Result<()>

Initializes the SixelDither.

pub fn apply_palette( &mut self, pixels: &[u8], width: usize, height: usize, ) -> Result<Vec<u8>>

Apply the palette to the SixelDither.

impl SixelDither

pub fn make_palette(&mut self, data: &[u8]) -> Result<Vec<u8>>

Creates a color palette.

pub fn quant_apply_palette(&mut self, data: &mut [u8]) -> Result<Vec<u8>>

Applies color palette into the specified pixel buffers.

Trait Implementations

impl Clone for SixelDither

fn clone(&self) -> SixelDither

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SixelDither

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

Formats the value using the given formatter.

impl Default for SixelDither

fn default() -> SixelDither

Returns the “default value” for a type.

impl PartialEq for SixelDither

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