Bezier curve listen to know the name may draw a graceful curve, but up is the control point, it is how to control it, and thought the graphics are always associated with this control point is not on hold in a hurry, every minute to get.
Beisier quadratic Bezier curves and cubic Bezier curves, micro letter applet is used (other probably almost)
quadratic Bezier curve:
CanvasContext.quadraticCurveTo(number cpx, number cpy, number x, number y)
Cubic Bezier curves:
CanvasContext.bezierCurveTo(number cp1x, number cp1y, number cp2x, number cp2y, number x, number y)
Details can be viewed using the official document:

If I want to draw a heart, how do?
First try quadratic Bezier curve tools
do not seem too perfect, then try cubic Bezier curve tool
perfect! ! !
Next, pass several parameters which will be able to function

Tool is very simple, just to write code convenience, Buchengjingyi.
