CanvasGradient class - dart:html library (original) (raw)

An opaque canvas object representing a gradient.

Created by calling the methodsCanvasRenderingContext2D.createLinearGradient orCanvasRenderingContext2D.createRadialGradient on aCanvasRenderingContext2D object.

Example usage:

var canvas = new CanvasElement(width: 600, height: 600);
var ctx = canvas.context2D;
ctx.clearRect(0, 0, 600, 600);
ctx.save();
// Create radial gradient.
CanvasGradient gradient = ctx.createRadialGradient(0, 0, 0, 0, 0, 600);
gradient.addColorStop(0, '#000');
gradient.addColorStop(1, 'rgb(255, 255, 255)');
// Assign gradients to fill.
ctx.fillStyle = gradient;
// Draw a rectangle with a gradient fill.
ctx.fillRect(0, 0, 600, 600);
ctx.save();
document.body.children.add(canvas);
