Struct RadialGradient 

pub struct RadialGradient {
    pub inner_center: Vector2D,
    pub inner_radius: f64,
    pub outer_center: Vector2D,
    pub outer_radius: f64,
    pub stops: Vec<(f64, String)>,
}

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.

Fields

inner_center: Vector2D

The center of the inner circle of the gradient.

inner_radius: f64

The radius of the inner circle.

outer_center: Vector2D

The center of the outer circle of the gradient.

outer_radius: f64

The radius of the outer circle.

stops: Vec<(f64, String)>

The ordered list of color stops, each containing a position (0.0 to 1.0) and a CSS color string.

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_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.
