roundRect method
The CanvasRenderingContext2D.roundRect()
method of the Canvas 2D API
adds a rounded rectangle to the current path.
The radii of the corners can be specified in much the same way as the CSS
border-radius
property.
Like other methods that modify the current path, this method does not directly render anything. To draw the rounded rectangle onto a canvas, you can use the CanvasRenderingContext2D.fill or CanvasRenderingContext2D.stroke methods.
