CanvasRenderingContext2D: createConicGradient() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨April 2023⁩.

The CanvasRenderingContext2D.createConicGradient() method of the Canvas 2D API creates a gradient around a point with given coordinates.

This method returns a conic CanvasGradient. To be applied to a shape, the gradient must first be assigned to the fillStyle or strokeStyle properties.

Note: Gradient coordinates are global, i.e., relative to the current coordinate space. When applied to a shape, the coordinates are NOT relative to the shape's coordinates.

Syntax

createConicGradient(startAngle, x, y)

Parameters

startAngle: The angle at which to begin the gradient, in radians. The angle starts from a line going horizontally right from the center, and proceeds clockwise.
x: The x-axis coordinate of the center of the gradient.
y: The y-axis coordinate of the center of the gradient.

Return value

CanvasGradient: A conic CanvasGradient.

This example initializes a conic gradient using the createConicGradient() method. Five color stops between around the center coordinate are then created. Finally, the gradient is assigned to the canvas context, and is rendered to a filled rectangle.

HTML

html

<canvas id="canvas" width="240" height="240"></canvas>

JavaScript

const canvas = document.getElementById("canvas");
const ctx = canvas.getContext("2d");

// Create a conic gradient
// The start angle is 0
// The center position is 100, 100
const gradient = ctx.createConicGradient(0, 100, 100);

// Add five color stops
gradient.addColorStop(0, "red");
gradient.addColorStop(0.25, "orange");
gradient.addColorStop(0.5, "yellow");
gradient.addColorStop(0.75, "green");
gradient.addColorStop(1, "blue");

// Set the fill style and draw a rectangle
ctx.fillStyle = gradient;
ctx.fillRect(20, 20, 200, 200);
