Struct rgb::alt::GrayAlpha

#[repr(C)]
pub struct GrayAlpha<T, A = T>(pub T, pub A);

A pixel for grayscale value + alpha components (rgb crate v0.8)

Through a Deref hack it renames the fields from .0 and .1 to .v (value) and .a (alpha)

Tuple Fields

0: T

Grayscale Component

This field has been renamed to .v

1: A

Alpha Component. This field has been renamed to .a.

Implementations

impl<T: Copy> GrayAlpha_v08<T>

pub fn value(self) -> T

Reads the .0 field

This function isn’t necessary, but it is forwards-compatible with the next major version of the RGB crate.

pub fn value_mut(&mut self) -> &mut T

Exposes the .0 field for writing

This function isn’t necessary, but it is forwards-compatible with the next major version of the RGB crate.

impl<T: Copy> GrayAlpha_v08<T>

pub const fn new(value: T, alpha: T) -> Self

Creates a new GrayAlpha_v08 pixel type from its components.

Alternatively, you can use struct literal syntax to create the new pixel type:

use rgb::GrayAlpha_v08;

let pixel = GrayAlpha_v08 {0 : value, 1 : alpha};

Provide a mutable view of only Gray component (leaving out alpha).

impl<T: Copy, A: Clone> GrayAlpha<T, A>

pub fn with_alpha(&self, a: A) -> Self
