Struct Gradient 

pub struct Gradient {
    pub kind: GradientKind,
    pub extend: Extend,
    pub interpolation_cs: ColorSpaceTag,
    pub hue_direction: HueDirection,
    pub interpolation_alpha_space: InterpolationAlphaSpace,
    pub stops: ColorStops,
}

Definition of a gradient that transitions between two or more colors.

Fields

kind: GradientKind

Kind and properties of the gradient.

extend: Extend

Extend mode.

interpolation_cs: ColorSpaceTag

The color space to be used for interpolation.

The gradient’s color ramps will be interpolated linearly in this color space between the specified color stops.

This defaults to sRGB.

hue_direction: HueDirection

When interpolating within a cylindrical color space, the direction for the hue.

This is interpreted as described in CSS Color Module Level 4 § 12.4.

interpolation_alpha_space: InterpolationAlphaSpace

Alpha space to be used for interpolation

stops: ColorStops

Color stop collection.

Implementations

impl Gradient

pub fn new_linear(start: impl Into<Point>, end: impl Into<Point>) -> Gradient

Creates a new linear gradient for the specified start and end points.

pub fn new_radial(center: impl Into<Point>, radius: f32) -> Gradient

Creates a new radial gradient for the specified center point and radius.

pub fn new_two_point_radial( start_center: impl Into<Point>, start_radius: f32, end_center: impl Into<Point>, end_radius: f32, ) -> Gradient

Creates a new two point radial gradient for the specified center points and radii.

pub fn new_sweep( center: impl Into<Point>, start_angle: f32, end_angle: f32, ) -> Gradient

Creates a new sweep gradient for the specified center point, start and end angles.

pub const fn with_extend(self, mode: Extend) -> Gradient

Builder method for setting the gradient extend mode.

pub const fn with_interpolation_cs( self, interpolation_cs: ColorSpaceTag, ) -> Gradient

Builder method for setting the interpolation color space.

pub const fn with_interpolation_alpha_space( self, interpolation_alpha_space: InterpolationAlphaSpace, ) -> Gradient

Builder method for setting the interpolation alpha space.

pub const fn with_hue_direction(self, hue_direction: HueDirection) -> Gradient

Builder method for setting the hue direction when interpolating within a cylindrical color space.

pub fn with_stops(self, stops: impl ColorStopsSource) -> Gradient

Builder method for setting the color stop collection.

pub fn with_alpha(self, alpha: f32) -> Gradient

Returns the gradient with the alpha component for all color stops set to alpha.

pub fn multiply_alpha(self, alpha: f32) -> Gradient

Returns the gradient with the alpha component for all color stops multiplied by alpha.

Trait Implementations

impl Clone for Gradient

fn clone(&self) -> Gradient

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Gradient

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

Formats the value using the given formatter.

impl Default for Gradient

fn default() -> Gradient

Returns the “default value” for a type.

impl EncodeExt for Gradient

fn encode_into( &self, paints: &mut Vec<EncodedPaint>, transform: Affine, _tint: Option<Tint>, ) -> Option<Paint>

Encode the gradient into a paint.

impl<'a> From<&'a Gradient> for Brush<ImageBrush<&'a ImageData>, &'a Gradient>

fn from( gradient: &'a Gradient, ) -> Brush<ImageBrush<&'a ImageData>, &'a Gradient>

Converts to this type from the input type.

impl<I> From<Gradient> for Brush<I>

fn from(g: Gradient) -> Brush<I>

Converts to this type from the input type.

impl PartialEq for Gradient

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

Tests for self and other values to be equal, and is used by ==.

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

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