Animate a Fill Circle using Canvas
问题 Basically I want to be able to Fill a Circle using canvas, but it animate to a certain percentage. I.e only have the circle fill up 80% of the way. My canvas knowledge isn't amazing, Here is an image i made in photoshop to display what i want. I want the circle to start empty and then Fill up to say 70% of the circle. Is this possible with Canvas, if so? can anyone shed some light on how to do it? Here is a fiddle of what I've managed http://jsfiddle.net/6Vm67/ var canvas = document
