Struct ril::L

pub struct L(pub u8);

Represents an L, or luminance pixel that is stored as only one single number representing how bright, or intense, the pixel is.

This can be thought of as the “unit channel” as this represents only a single channel in which other pixel types can be composed of.

Tuple Fields

0: u8

The luminance value of the pixel, between 0 and 255.

Implementations

impl L

pub const fn new(l: u8) -> Self

Creates a new L pixel with the given luminance value.

pub const fn value(&self) -> u8

Returns the luminance value of the pixel.

Trait Implementations

impl Clone for L

fn clone(&self) -> L

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for L

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for L

fn default() -> L

Returns the “default value” for a type.

impl From<BitPixel> for L

fn from(bit: BitPixel) -> Self

Converts to this type from the input type.

impl From<Dynamic> for L

fn from(pixel: Dynamic) -> Self

Converts to this type from the input type.

impl From<L> for BitPixel

fn from(l: L) -> Self

Converts to this type from the input type.

impl From<L> for Dynamic

fn from(pixel: L) -> Self

Converts to this type from the input type.

impl From<L> for Rgb

fn from(L: L) -> Self

Converts to this type from the input type.

impl From<L> for Rgba

fn from(L: L) -> Self

Converts to this type from the input type.

impl From<Rgb> for L

fn from(_: Rgb) -> Self

Converts to this type from the input type.

impl From<Rgba> for L

fn from(rgba: Rgba) -> Self

Converts to this type from the input type.

impl PartialEq<L> for L

fn eq(&self, other: &L) -> bool

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

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

This method tests for !=.

impl Pixel for L

type Data = [u8; 1]

fn inverted(&self) -> Self

Returns the inverted value of this pixel.

fn from_pixel_data(data: PixelData) -> Result<Self>

Creates this pixel from raw data.

fn as_pixel_data(&self) -> PixelData

Creates raw pixel data from this pixel type.

fn as_bytes(&self) -> Self::Data

Turns this pixel into bytes.

fn merge_with_alpha(self, other: Self, alpha: u8) -> Self

Merges this pixel with the given overlay pixel, where the alpha of the overlay pixel is known. This is used in anti-aliasing.

fn from_dynamic(dynamic: Dynamic) -> Self

Creates this pixel from any dynamic pixel…dynamically at runtime. Different from the From/Into traits.

fn luminance(&self) -> u8 where
    Self: Into<L>, 

The luminance of the pixel.

fn merge(self, other: Self) -> Self

Merges this pixel with the given overlay pixel, taking into account alpha.

fn overlay(self, other: Self, mode: OverlayMode) -> Self

Overlays this pixel with the given overlay pixel, abiding by the given overlay mode.

fn overlay_with_alpha(self, other: Self, mode: OverlayMode, alpha: u8) -> Self

Overlays this pixel with the given overlay pixel, abiding by the given overlay mode with the given alpha.
