Struct RadialGradient 

pub struct RadialGradient { /* private fields */ }

A radial gradient defined by inner and outer circles and a list of color stops.

Used to create smooth color transitions radiating outward from a center point for fill or stroke operations on the canvas.

Implementations

impl RadialGradient

Implements construction and canvas gradient creation for RadialGradient.

pub fn create( inner_center: Vector2D, inner_radius: f64, outer_center: Vector2D, outer_radius: f64, stops: Vec<(f64, String)>, ) -> RadialGradient

Creates a new radial gradient from inner and outer circles and color stops.

Arguments

• Vector2D - The inner circle center.
• f64 - The inner circle radius.
• Vector2D - The outer circle center.
• f64 - The outer circle radius.
• Vec<(f64, String)> - The color stops as (position, color) pairs.

Returns

• RadialGradient - The new gradient.

pub fn to_canvas_gradient( &self, context: &CanvasRenderingContext2d, ) -> Option<CanvasGradient>

Creates a CanvasGradient from this gradient definition on the given context.

Arguments

• &CanvasRenderingContext2d - The canvas context.

Returns

• Option<CanvasGradient> - The canvas gradient, or None if creation failed.

Trait Implementations

impl Clone for RadialGradient

fn clone(&self) -> RadialGradient

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RadialGradient

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

Formats the value using the given formatter.

impl PartialEq for RadialGradient

fn eq(&self, other: &RadialGradient) -> 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.
