Struct druid::piet::image_crate::Rgb
pub struct Rgb<T>(pub [T; 3]);
Expand description
RGB colors.
For the purpose of color conversion, as well as blending, the implementation of Pixel
assumes an sRGB
color space of its data.

T: Primitive + Enlargeable,
impl<T> Pixel for Rgb<T>where T: Primitive + Enlargeable,
§const CHANNEL_COUNT: u8 = 3u8
const CHANNEL_COUNT: u8 = 3u8
The number of channels of this pixel type.
§fn channels_mut(&mut self) -> &mut [T] ⓘ
fn channels_mut(&mut self) -> &mut [T] ⓘ
Returns the components as a mutable slice
§const COLOR_MODEL: &'static str = "RGB"
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)
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>
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(slice: &[T]) -> &Rgb<T>
fn from_slice(slice: &[T]) -> &Rgb<T>
Returns a view into a slice. Read more
