[][src]Struct rustbitmap::bitmap::rgba::Rgba

pub struct Rgba { /* fields omitted */ }

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

Methods

impl Rgba[src]

pub fn white() -> Rgba[src]

Create the color white

pub fn black() -> Rgba[src]

Create the color black

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

Create a color by specifying red, green and blue

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

Create a color by specifying blue, green and red

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

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

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

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

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

Change the current color to the other color

pub fn is_transparent(&self) -> bool[src]

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

pub fn get_red(&self) -> u8[src]

get the amount of red in the pixel

pub fn get_green(&self) -> u8[src]

get the amount of green in the pixel

pub fn get_blue(&self) -> u8[src]

get the amount of blue in the pixel

pub fn get_alpha(&self) -> u8[src]

get the amount of alpha in the pixel

impl Rgba[src]

Methods used to manipulate the rgba color in a certain way

pub fn color_to_gray(&mut self)[src]

Convert pixel color to gray scale

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

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
[src]

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