Struct Rgba

pub struct Rgba { /* private fields */ }

Rgba represents the colors red, green, blue, alpha. Alpha represents the transparency of the image while red, green and blue represent the intensity of the colors.

Alpha is managed between 0 - 100 Red Green and Blue is managed between 0 - 255

Implementations

impl Rgba

pub fn white() -> Rgba

Create the color white

pub fn black() -> Rgba

Create the color black

pub fn rgb(red: u8, green: u8, blue: u8) -> Rgba

Create a color by specifying red, green and blue

pub fn bgr(blue: u8, green: u8, red: u8) -> Rgba

Create a color by specifying blue, green and red

pub fn bgra(blue: u8, green: u8, red: u8, alpha: u8) -> Rgba

Create a color by specifying blue, green, red and alpha

pub fn rgba(red: u8, green: u8, blue: u8, alpha: u8) -> Rgba

Create a color by specifying red, green, blue and alpha

pub fn recolor_to(&mut self, other: &Self)

Change the current color to the other color

pub fn is_transparent(&self) -> bool

Check if the alpha value is less then 100 (Visible)

pub fn get_red(&self) -> u8

get the amount of red in the pixel

pub fn get_green(&self) -> u8

get the amount of green in the pixel

pub fn get_blue(&self) -> u8

get the amount of blue in the pixel

pub fn get_alpha(&self) -> u8

get the amount of alpha in the pixel

impl Rgba

Methods used to manipulate the rgba color in a certain way

pub fn color_to_gray(&mut self)

Convert pixel color to gray scale

pub fn linear_interpolation( lhs: &Rgba, lhs_factor: f32, rhs: &Rgba, rhs_factor: f32, ) -> Result<Rgba, &'static str>

Blur 2 color’s together

By passing in different factors, you can effect how much one color will effect the other.

@param {&Rgba} first color to linear_interpolation @param {f32} factor how much the first color will effect the outcome @param {&Rgba} second color to linear_interpolation @param {f32} factor how much the second color will effect the outcome @return {Rgba} new color of the 2 colors blurred together

pub fn cubic_interpolate( p0: &Rgba, p1: &Rgba, p2: &Rgba, p3: &Rgba, factor: f32, ) -> Rgba

Use cubic interpolation on 4 colors between range [0, 1] then find x as a factor that is between [0, 1] (ex. 0.5)

Trait Implementations

impl Clone for Rgba

fn clone(&self) -> Rgba

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Rgba

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

Formats the value using the given formatter.

impl Display for Rgba

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

Formats the value using the given formatter.

impl PartialEq for Rgba

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