Struct Color

Source

pub struct Color {}

Expand description

A utility struct for color-related operations.

Implementations§

Source §

impl Color

Source

pub fn luminance_from_rgba(rgba: &[u8; 4]) -> f64

Calculates the luminance of an RGBA color.

§Arguments

rgba - A reference to a 4-element array representing a color in RGBA format (0–255 range).

§Returns

A f64 value representing the luminance (brightness) of the color, normalized to the 0.0–1.0 range.

§Example

use typistapp::color::Color;

let luminance = Color::luminance_from_rgba(&[255, 255, 255, 255]);
assert!(luminance > 0.9);

Source

pub fn convert_rgb_to_yuv(r: f64, g: f64, b: f64) -> [f64; 3]

Converts an RGB color to YUV color space.

§Arguments

r - Red component (0.0–1.0).
g - Green component (0.0–1.0).
b - Blue component (0.0–1.0).

§Returns

A [f64; 3] array where the elements represent the Y (luminance), U, and V components respectively.

Source

pub fn luminance_from_yuv(yuv: &[f64; 3]) -> f64

Extracts the luminance component (Y) from a YUV color.

§Arguments

yuv - A reference to a 3-element array representing a YUV color.

§Returns

A f64 value representing the luminance.
