Expand description

Represents one colour, with optimisations in the cases there is no alpha, or all three components are equal (that is, grey).

Variants

Rgba(u8, u8, u8, u8)

Contains all four components.

Tuple Fields of Rgba

0: u81: u82: u83: u8

Rgb(u8, u8, u8)

Completely opaque RGB.

Tuple Fields of Rgb

0: u81: u82: u8

Grey(u8, u8)

All three colours are equal.

Tuple Fields of Grey

0: u81: u8

GreyNoAlpha(u8)

Completely opaque grey.

Tuple Fields of GreyNoAlpha

0: u8

Implementations

[src]

impl Colour

[src]

pub fn is_opaque(&self) -> bool

Returns whether a colour is opaque, that is no alpha value is present.

[src]

pub fn to_rgb(&self) -> (u8, u8, u8 )

Converts this colour to its rgb components.

Safety: it must be called only on opaque colours.

[src]

pub fn to_rgba(&self) -> (u8, u8, u8, u8 )

Converts this colour to its rgba components.
