Struct image::Rgb

#[repr(C)]
pub struct Rgb<T>(pub [T; 3]);

RGB colors.

For the purpose of color conversion, as well as blending, the implementation of Pixel assumes an sRGB color space of its data.

Tuple Fields

0: [T; 3]

impl<T> Index<usize> for Rgb<T>

type Output = T

The returned type after indexing.

fn index(&self, _index: usize) -> &T

Performs the indexing (container[index]) operation.

impl<T> IndexMut<usize> for Rgb<T>

fn index_mut(&mut self, _index: usize) -> &mut T

Performs the mutable indexing (container[index]) operation.

impl<T: PartialEq> PartialEq for Rgb<T>

fn eq(&self, other: &Rgb<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: Primitive + Enlargeable> Pixel for Rgb<T>

type Subpixel = T

The scalar type that is used to store each channel in this pixel.

const CHANNEL_COUNT: u8 = 3u8

The number of channels of this pixel type.

fn channels(&self) -> &[T]

Returns the components as a slice.

fn channels_mut(&mut self) -> &mut [T]

Returns the components as a mutable slice

const COLOR_MODEL: &'static str = "RGB"

A string that can help to interpret the meaning each channel See gimp babl.

fn channels4(&self) -> (T, T, T, T)

👎Deprecated since 0.24.0: Use channels() or channels_mut()

Returns the channels of this pixel as a 4 tuple. If the pixel has less than 4 channels the remainder is filled with the maximum value

fn from_channels(a: T, b: T, c: T, d: T) -> Rgb<T>

👎Deprecated since 0.24.0: Use the constructor of the pixel, for example Rgba([r,g,b,a]) or Pixel::from_slice

Construct a pixel from the 4 channels a, b, c and d. If the pixel does not contain 4 channels the extra are ignored.

fn from_slice_mut(slice: &mut [T]) -> &mut Rgb<T>

Returns mutable view into a mutable slice.

fn to_rgb(&self) -> Rgb<T>

where F: FnMut(T) -> T,

Apply the function f to each channel of this pixel.

fn apply<F>(&mut self, f: F)

where F: FnMut(T) -> T,

Apply the function f to each channel of this pixel.

fn map_with_alpha<F, G>(&self, f: F, g: G) -> Rgb<T>

where F: FnMut(T) -> T, G: FnMut(T) -> T,

Apply the function f to each channel except the alpha channel. Apply the function g to the alpha channel.
