Provided Methods

fn duplicate(&self) -> Option<Color>

Creates a copy of self.

Returns

A new copy of self.

fn components(&self, format: &mut Value) -> Vec<f64>

Get the component values of the color in format.

format

A Babl pointer

Returns

The color components If value format not supported return NULL and components_length set to 0.

fn rgba(&self) -> (f64, f64, f64, f64)

Retrieves the current set color as linear light non premultipled RGBA data, any of the return pointers can be omitted.

Returns

red

red return location.

green

green return location.

blue

blue return location.

alpha

alpha return location.

fn set_components(&self, format: &mut Value, components: &[f64])

Set the color using the component values as format.

format

A Babl pointer

components

fn set_rgba(&self, red: f64, green: f64, blue: f64, alpha: f64)

Set color as linear light non premultipled RGBA data

red

red value

green

green value

blue

blue value

alpha

alpha value

fn string(&self) -> Option<GString>
