Struct rgb::Gray

#[repr(C)]
pub struct Gray<T>(pub T);

Available on non-crate feature unstable-experimental only.

A Grayscale pixel (rgb crate v0.8)

Tuple Fields

0: T

Grayscale Component. This field will be renamed to v.

Implementations

impl<T: Copy> Gray_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.

pub fn with_alpha(self, add_alpha_value: T) -> GrayAlpha_v08<T>

Add alpha component to this pixel

impl<T: Copy> Gray_v08<T>

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

Creates a new Gray_v08 pixel type from its components.

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

use rgb::Gray_v08;

let pixel = Gray_v08 {0 : value};
