Drawing an arc in KineticJS

Question

I know you can draw a wedge using a Kinetic.Wedge:

  var compassArc = new Kinetic.Wedge({
    x: stage.getWidth() / 2,
    y: stage.getHeight() / 2,
    radius: 70,
    angleDeg: 60,
    fill: 'red',
    stroke: 'black',
    strokeWidth: 4,
    rotationDeg: -90
  });

This draws a "pizza slice" with a black outline around the whole thing. I just want the "crust" of the pizza, with no straight lines coming back to the center of the circle. How can I do this?

Setting the fill to null removes the red but leaves the outline.

How about creating a custom shape fot this using arc?

Please keep in mind that not to close path and not to fill strokes. if so, you will get what you want. It is a KineticJS object, so that you can drag around if you want.

Here is the working example.

var arc = new Kinetic.Shape({
    drawFunc: function(canvas) {
        var context = canvas.getContext();
        var x = stage.getWidth() / 2;
        var y = stage.getHeight()/2;
        var radius = 70;
        var startAngle = 1 * Math.PI;
        var endAngle = 0 * Math.PI;
        var context = canvas.getContext('2d');
        context.beginPath();
        context.arc(x, y, radius, startAngle, endAngle, false);
        //context.closePath();
        canvas.stroke(this);
    },
    fill: '#00D2FF',
    stroke: 'black',
    strokeWidth: 4,
    draggable:true
});
