[−]
[src]
pub struct RGBA { pub red: u8, pub green: u8, pub blue: u8, pub alpha: u8, }
A color with red, green, blue, and alpha components, in a byte each.
Fields
red: u8
The red component.
green: u8
The green component.
blue: u8
The blue component.
alpha: u8
The alpha component.
Methods
impl RGBA
[src]
fn from_floats(red: f32, green: f32, blue: f32, alpha: f32) -> Self
Constructs a new RGBA value from float components. It expects the red, green, blue and alpha channels in that order, and all values will be clamped to the 0.0 ... 1.0 range.
fn transparent() -> Self
Returns a transparent color.
fn new(red: u8, green: u8, blue: u8, alpha: u8) -> Self
Same thing, but with u8
values instead of floats in the 0 to 1 range.
fn red_f32(&self) -> f32
Returns the red channel in a floating point number form, from 0 to 1.
fn green_f32(&self) -> f32
Returns the green channel in a floating point number form, from 0 to 1.
fn blue_f32(&self) -> f32
Returns the blue channel in a floating point number form, from 0 to 1.
fn alpha_f32(&self) -> f32
Returns the alpha channel in a floating point number form, from 0 to 1.
