Struct jascpal::Palette

pub struct Palette { /* fields omitted */ }

A Palette.

Implementations

impl Palette

pub fn new() -> Self

Create an empty palette.

pub fn read_from(input: impl Read) -> Result<Self, ReadPaletteError>

Read a palette from an input stream.

pub fn write_to(&self, output: impl Write) -> Result<(), Error>

Write a palette to an output stream.

pub fn into_inner(self) -> Vec<Color>

Return the colours in a Vec so it can be manipulated.

It can later be wrapped back into a Palette instance using Palette::from(vec).

pub fn colors(&self) -> &[Color]

Return the colours as a slice.

pub fn colors_mut(&mut self) -> &mut Vec<Color>

Return the colours as a mutable vector.

pub fn len(&self) -> usize

Returns the number of colours in this palette.

pub fn is_empty(&self) -> bool

Returns true if this palette contains 0 colours.

pub fn add(&mut self, color: Color)

Add a colour at the end of the palette.

pub fn to_bytes(&self) -> Vec<u8>

Serialize the palette to a byte vector.
