Struct pastel::ColorScale

source · [−]

pub struct ColorScale { /* private fields */ }

Expand description

The representation of a color scale. The first ColorStop (position 0.0) defines the left end color. The last ColorStop (position 1.0) defines the right end color.

Implementations

source

impl ColorScale

source

pub fn empty() -> Self

Create an empty ColorScale.

source

pub fn add_stop(&mut self, color: Color, position: Fraction) -> &mut Self

Add a Color at the given position.

source

pub fn sample(
 &self,
 position: Fraction,
 mix: &dyn Fn(&Color, &Color, Fraction) -> Color
) -> Option<Color>

Get the color at the given position using the mixing function.

Note:

No color is returned if position isn’t between two color stops or the ColorScale is empty.
