Example
Draw a rectangle and fill with a radial/circular gradient:
JavaScript:
var c=document.getElementById("myCanvas");
var
ctx=c.getContext("2d");
var grd=ctx.createRadialGradient(75,50,5,90,60,100);
grd.addColorStop(0,"red");
grd.addColorStop(1,"white");
// Fill with gradient
ctx.fillStyle=grd;
ctx.fillRect(10,10,150,100);

Definition and Usage
The createRadialGradient() method creates a radial/circular gradient object.
The gradient can be used to fill rectangles, circles, lines, text, etc.
Tip: Use this object as the value to the strokeStyle or fillStyle properties.
Tip: Use the addColorStop() method to specify different colors, and where to position the colors in the gradient object.
JavaScript syntax: | context.createRadialGradient(x0,y0,r0,x1,y1,r1); |
