Struct GradientStops 

Source 
pub struct GradientStops {
    pub start: ColorStop,
    pub middle: Vec<GradientStop>,
    pub end: ColorStop,
}
Expand description

Stops in a gradient.

Use stops! to create a new instance, you can convert from arrays for simpler gradients.

Fields§

§start: ColorStop

First color stop.

§middle: Vec<GradientStop>

Optional stops between start and end.

§end: ColorStop

Last color stop.

Implementations§

Source§

impl GradientStops

Source

pub fn new(start: impl Into<Rgba>, end: impl Into<Rgba>) -> GradientStops

Gradients stops with two colors from start to end.

Source

pub fn from_colors<C>(colors: &[C]) -> GradientStops
where C: Into<Rgba> + Copy,

Gradient stops from colors spaced equally.

The stops look like a sequence of positional only color stops but the proportional distribution is pre-calculated.

If less than 2 colors are given, the missing stops are filled with transparent color.

Source

pub fn from_stripes<C, T>(colors: &[C], transition: T) -> GradientStops
where C: Into<Rgba> + Copy, T: Into<Factor>,

Gradient stops from colors forming stripes of same length.

The transition parameter controls relative length of the transition between two stripes. 1.0 or 100.pct() is the length of a stripe, set to 0.0 to get hard-lines.

Source

pub fn from_stops<C>(stops: &[C]) -> GradientStops
where C: Into<ColorStop> + Copy,

Gradient stops from color stops.

If less than 2 colors are given, the missing stops are filled with transparent color.

Source

pub fn set_alpha<A>(&mut self, alpha: A)
where A: Into<RgbaComponent>,

Set the alpha of all colors in the gradient.

Source

pub fn layout_linear( &self, axis: LayoutAxis, extend_mode: ExtendMode, line: &mut PxLine, render_stops: &mut Vec<GradientStop>, )

Computes the linear gradient in the current LAYOUT context.

The axis value selects the layout axis the offsets layout on.

The render_stops content is replaced with stops with offset in the 0..=1 range.

The line points are moved to accommodate input offsets outside the line bounds.

Source

pub fn layout_radial( &self, axis: LayoutAxis, extend_mode: ExtendMode, render_stops: &mut Vec<GradientStop>, )

Computes the layout for a radial gradient.

The render_stops content is replace with stops with offset in the 0..=1 range.

Source

pub fn len(&self) -> usize

Number of stops.
