Enum conrod_core::color::Color

pub enum Color {
    Rgba(f32, f32, f32, f32),
    Hsla(f32, f32, f32, f32),
}

Color supporting RGB and HSL variants.

Variants

Rgba(f32, f32, f32, f32)

Red, Green, Blue, Alpha - All values' scales represented between 0.0 and 1.0.

Hsla(f32, f32, f32, f32)

Hue, Saturation, Lightness, Alpha - all values scales represented between 0.0 and 1.0.

Implementations

impl Color

pub fn complement(self) -> Color

Produce a complementary color. The two colors will accent each other. This is the same as rotating the hue by 180 degrees.

pub fn luminance(&self) -> f32

Calculate and return the luminance of the Color.

pub fn plain_contrast(self) -> Color

Return either black or white, depending which contrasts the Color the most. This will be useful for determining a readable color for text on any given background Color.

pub fn to_hsl(self) -> Hsla

Extract the components of a color in the HSL format.

pub fn to_rgb(self) -> Rgba

Extract the components of a color in the RGB format.

pub fn to_fsa(self) -> [f32; 4]

Extract the components of a color in the RGB format within a fixed-size array.

pub fn to_byte_fsa(self) -> [u8; 4]

Same as to_fsa, except r, g, b and a are represented in byte form.

pub fn with_luminance(self, l: f32) -> Color

Return the same color but with the given luminance.

pub fn alpha(self, alpha: f32) -> Color

Return the same color but with the alpha multiplied by the given alpha.

pub fn with_alpha(self, a: f32) -> Color

Return the same color but with the given alpha.

pub fn highlighted(self) -> Color

Return a highlighted version of the current Color.

pub fn clicked(&self) -> Color

Return a clicked version of the current Color.

pub fn invert(self) -> Color

Return the Color's invert.

pub fn red(&self) -> f32

Return the red value.

pub fn green(&self) -> f32

Return the green value.

pub fn blue(&self) -> f32

Return the blue value.

pub fn set_red(&mut self, r: f32)

Set the red value.

pub fn set_green(&mut self, g: f32)

Set the green value.

pub fn set_blue(&mut self, b: f32)

Set the blue value.
