Struct tiny_skia::PremultipliedColor

pub struct PremultipliedColor { /* private fields */ }

A premultiplied RGBA color value, holding four floating point components.

Guarantees

• All values are in 0..=1 range.
• RGB components are <= A.

Implementations

impl PremultipliedColor

pub fn red(&self) -> f32

Returns color’s red component.

• The value is guarantee to be in a 0..=1 range.
• The value is <= alpha.

pub fn green(&self) -> f32

Returns color’s green component.

• The value is guarantee to be in a 0..=1 range.
• The value is <= alpha.

pub fn blue(&self) -> f32

Returns color’s blue component.

• The value is guarantee to be in a 0..=1 range.
• The value is <= alpha.

pub fn alpha(&self) -> f32

Returns color’s alpha component.

• The value is guarantee to be in a 0..=1 range.

pub fn demultiply(&self) -> Color

Returns a demultiplied color.

pub fn to_color_u8(&self) -> PremultipliedColorU8

Converts into PremultipliedColorU8.

Trait Implementations

impl Clone for PremultipliedColor

fn clone(&self) -> PremultipliedColor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PremultipliedColor

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

Formats the value using the given formatter.

impl PartialEq for PremultipliedColor

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
