问题,请看图。图1,fill绘制扇形,用closePath()收口,如何去除边线颜色。//用fill绘制扇形
c.beginPath();
c.fillStyle = "coral";
c.moveTo(200, 300);
c.arc(200, 300, 200, Math.PI * 7 / 6, Math.PI * 11 / 6);
c.closePath();
c.fill();
c.beginPath();
c.fillStyle = "blanchedalmond";
c.moveTo(200, 300);
c.arc(200, 300, 100, Math.PI * 7 / 6, Math.PI * 11 / 6);
c.closePath();
c.fill()
//用stroke绘制扇形
c.beginPath();
c.strokeStyle = "coral";
c.lineWidth = 100;
c.arc(600, 300, 150, Math.PI * 11 / 6, Math.PI * 7 / 6, true);
c.stroke();
